Foreword
One of the Agencys key aims, as set out in our Strategic Plan for 2005-10,
is to enable consumers to make informed choices
For consumers with food allergies or food intolerances, this is particularly
important, as eating even a small amount of the food to which they are
sensitive can make them very ill and in some cases, cause potentially fatal
anaphylactic reactions.
Recent changes in food labelling legislation have led to significant
improvements in the labelling of allergenic ingredients in foods, but this
legislation does not address concerns about possible allergen crosscontamination. Whilst some food producers and retailers are already
using various forms of advisory labelling to warn consumers about such
risks, consumers are concerned about the possible overuse of such
labelling and find the variety of phrases used confusing.
After being approached by industry, the Agency therefore decided to
produce best practice guidance on how to manage food allergens during
food production and the process for deciding whether or not advisory
labelling is appropriate. This guidance builds on information that has
already been produced by a number of industry organisations.
After consulting our stakeholders, we decided this guidance should be
voluntary. We hope that it will help enforcement officers advise
businesses on best practice but it should not be used as an enforcement
tool.
I would like to express my sincere thanks to all the stakeholders who
helped us in this task. Their input and expertise has helped produce a
document that will be of great benefit to both the food industry and to
the consumers who buy their products.

1. Introduction
1.1
Why is this Guidance needed?
A key aim of the Food Standards Agency is to enable consumers to make

informed choices. For those consumers with food allergies and food
intolerances, it is vital that they are fully informed about the nature and
contents of the foods they are buying.
There is evidence that the number of people who have adverse reactions
to foods such as cows milk, tree nuts, and peanuts is increasing1,2,3. People
with food allergies, and the people shopping for them, need clear
labelling of both allergenic ingredients and identification of possible
cross-contamination4 with allergens, in order to make informed food
choices.
There is general agreement between the food industry, consumer
support groups and enforcement bodies that excessive use of advisory
warning labels about the possible presence of allergens, not only
unnecessarily restricts consumer choice, but also devalues the impact of
the warning labels. Unlike the situation for deliberate ingredients, there
are currently no statutory controls governing labelling for the possible
low level presence of allergens due to the cross-contamination of foods
along the food supply chain.
The Agency, after being approached by the food industry and consulting
our stakeholders, decided it would be helpful to produce voluntary best
practice guidance to ensure allergen labelling could be as effective as
possible.
Advisory labelling should only be used when, following a thorough risk
assessment, there is a demonstrable and significant risk of allergen crosscontamination.
There is currently no consensus on the levels of allergens required to
provoke allergic reactions in consumers sensitive to various foods. This
document therefore sets out a qualitative approach to allergen
management and risk assessment. We anticipate revising this document
when further scientific evidence exists to enable quantitative allergen
management levels to be set.

In this document the term cross-contamination is used to describe accidental contact with an
allergenic food. This does not imply that the food is unwholesome or unhygienic.
1.2 Who is this Guidance intended for?

This document provides voluntary best practice advice to help food
producers and retailers assess the risks of cross-contamination of a food
product with an allergenic food or food ingredient and then to determine
whether or not advisory labelling is appropriate. It is intended to give a
generic overview of an approach to take in managing allergens and
providing advisory labelling. The overall approach described in this
guidance is relevant to any size of food business, although some of the
management techniques described will not be appropriate for smaller
businesses. A leaflet aimed at small and micro businesses has been
produced (for availability please see 1.3 below). In addition, the guidance
will be helpful for enforcement bodies, who advise food businesses on
best practice; however it should not be used as an enforcement tool.
Consumers with a food allergy, or those who buy for someone with a
food allergy, need to read and understand food labels in order to buy
food that is safe for them. It is important that consumers with food
allergies and food intolerances understand the meaning of any advisory
labelling used on a product in conjunction with the rest of the
information provided on the label, so that they can make appropriate
food choices. The Food Standards Agency provides guidance to help
consumers understand food labels, for example, via our
http://www.eatwell.gov.uk website.

2. Background and Purpose

2.1 Food Allergies and Intolerances
True food allergies are reproducible adverse reactions to a particular
food that involve the immune system. Virtually all known food allergens
are proteins; they can be present in the food in large amounts and often
survive food-processing conditions. Allergic reactions are characterised
by the rapid release of chemicals in the body that cause symptoms,
which can occur within minutes or may take an hour or more after
ingestion of the allergen. Whilst almost any food protein can cause an
allergic reaction in some people, the most common food allergens in
Europe are listed in the current allergen labelling legislation, these are:
cereals containing gluten wheat, rye, barley, oats, spelt, kamut;
crustaceans;
egg;
fish;
peanuts;
milk;
nuts Almond (Amygdalus communis L.), Hazelnut (Corylus avellana),
Walnut (Juglans regia), Cashew (Anacardium occidentale),
Pecan nut (Carya illinoiesis (Wangenh.) K. Koch), Brazil nut
(Bertholletia excelsa), Pistachio nut (Pistacia vera), Macadamia
nut and Queensland nut (Macadamia ternifolia);
soya;
sesame;
celery;
mustard; and
sulphur dioxide and sulphites.
Sulphur dioxide and sulphites are included in the EU list of allergens
because they can cause adverse reactions in some people. Those
affected generally already have asthma or other allergies and exposure
can trigger an asthma attack.
The proportion of the population with true food allergy is approximately
1-2% of adults and about 5-8% of children, which equates to about 1.5
million people in the UK. Very small amounts of an allergen, sometimes
less than one milligram (one thousandth of a gram), can trigger a reaction
which can be severe and on rare occasions fatal.
Coeliac disease is not an allergy, it is a life-long autoimmune disease,

which means that the body produces antibodies that attack its own
tissues. In coeliac disease this attack is triggered by gluten, a family of
proteins found in wheat, rye, barley and oats, which cause an
inflammatory response that damages the gut. Villi (tiny, finger-like
projections that line the gut) become inflamed and then flattened,
leading to a decreased surface area for absorption of nutrients from
food. People with coeliac disease can, as a result, have a wide range of
digestive symptoms and can suffer from nutritional deficiencies.
However, other people who do not have coeliac disease can be allergic
to cereals, such as wheat.
The avoidance of allergens due to cross-contamination is particularly
important for those allergenic foods which affect a higher proportion of
people as well as for those allergic people who are more likely to have
life-threatening reactions.
2.2 Purpose of this Document

Legislation and growing awareness of food allergies have focussed
attention on the identification of the food allergens that affect the most
people within the European Community; how they can be managed; and
the provision of appropriate consumer information. Legislation is now in
place (Directive 2003/89/EC and implementing Regulations in the UK)
requiring that where specified allergenic foods or their derivatives are
used as ingredients in prepacked foods, the relevant allergenic food
is indicated on the labelling. From 25 November 2005 products not
complying with this legislation were prohibited (but products that were
labelled before that date could continue to be sold whilst stocks lasted).
This legislation however does not cover allergenic foods that are
unintentionally present in food products as a result of crosscontamination at some point during the manufacture or transportation.
Further information on the legislative background can be found in
Appendix II.
Whilst guidance on this issue has already been produced by some
industry organisations, such as the Food and Drink Federation and the
Institute of Grocery Distribution, the purpose of this document is to set
out best practice guidance which food businesses can choose to follow
if they wish, that could be used across the various sectors of the food
industry to help maintain food safety and also maximise consumer
choice. This is so that there is a common understanding by food
producers and retailers, enforcement bodies, and consumers of when
warning labels might or might not be used, and what they mean for the
affected consumer.
This guidance sets out general principles that could be used to manage
specific allergenic ingredients in differing situations. The focus of this
guidance is the production of prepacked foods (for instance, food put
into packaging before sale, normally at a site separate from that where
the product is sold to the consumer), however, the general principles

could also be applied to non-prepacked foods.
Actions that may be appropriate in each specific situation need to be
determined by each individual food business. Different sectors of the
food industry may also wish to produce their own, more detailed
guidance or codes of practice, that build on the approach set out here
but be focussed on the particular aspects that are relevant to their
sector.
This document builds on previous advice and provides best practice
guidance on:
a)
the management of allergens in the manufacturing of food

products; and
b)
the adoption of a risk-based approach to the appropriate use of

label statements to advise consumers with food allergies or
severe food intolerances of the risk of unintentional allergen
cross-contamination in certain foods (see section 3).
2.3 Scope
For some time now food manufacturers have recognised that in certain
situations, there is a risk of cross-contamination of a food with nuts
and/or peanuts, which are not deliberately added to the food. This risk
was conveyed to customers in advisory warning statements such as may
contain nuts. More recently this sort of advisory labelling has been
extended to seeds such as sesame and other allergenic foods that can
also trigger potentially fatal anaphylactic reactions such as egg, milk, fish
and shellfish.
As well as the 12 allergenic foods for which there is statutory ingredient
listing in Europe, there are other allergens, where evidence is growing of
their public health importance. These may, in due course, be considered
for addition to the list of 12 allergens that require mandatory ingredients
labelling, for example: lupin, molluscs and kiwi fruit. Some people are
also allergic to latex that can be used in food packaging or in gloves used
by food handlers.
Appendix I describes the allergens currently covered by this legislation.
The guidance set out in this document has been drafted for the
management of any food allergen in any particular food-manufacturing
environment.
3. Allergen Risk Assessment,

Management and Communication
In order to avoid the unintentional presence of allergenic foods in
products it is necessary to evaluate the likelihood of unintentional
allergen cross-contamination across the supply chain, from raw materials
through to the finished product. Following completion of such a risk
analysis, manufacturers can then determine whether or not allergen
advisory labelling is appropriate on the finished product as sold to
consumers.
Risk analysis is made up of four stages:
1.
2.
3.
4.
Risk assessment what is the risk?

Risk management can the risk be managed?
Risk communication how should the risk be communicated?
Risk review has the risk changed?
Figure 1 sets out as a flow chart, the steps involved in this risk analysis.
Figure 4 shows the steps in the decision tree for managing allergens.
3.1 Allergen Risk Assessment

The first step in the risk assessment process is to consider if the
ingredient/product intentionally contains an allergenic foodstuff, and
whether any of these allergenic ingredients have the potential to crosscontaminate either foods produced on the premises, or ingredients
coming into the premises. Current legislation recognises 12 foods known
to commonly produce severe adverse reactions across the EU (see Annex
IIIa of Directive 2000/13/EC and Appendix I of this document), those
foods listed in the Annex have to be labelled whenever they are
intentionally used in a product. The 12 allergenic foods specified in the
legislation were determined by the European Food Safety Authority
(EFSA) Scientific Panel on Dietetic Products, Nutrition and Allergens, to
be important allergens that required food labels because of the severity
and prevalence of the allergy in Europe. These food types present the
greatest risk if present inadvertently and therefore should all be
considered in the risk assessment process. Other allergenic foods, for
example, lupin, molluscs, kiwi fruit, may be added to Annex IIIa in future,
dependent on the prevalence of adverse reactions in sensitive
consumers and their inherent potency to trigger severe reactions.

11
Appendix I contains further details on these 12 foods including

information on the prevalence of reactions to them. This information can
be used in the case-by-case risk assessment process. It should be noted
that Appendix I also includes information on ingredients derived from
the listed allergenic foods that are exempt from the allergen labelling
directive; these are not an allergen cross-contamination risk.
In reaching a judgement on the need for allergen warning labels a number
of factors have to be considered, including but not exclusively, the
following:
12
the amount of the allergenic food generally needed to provoke

a reaction in a sensitive individual (although it should be borne
in mind that different people can have different levels of
sensitivity, and that sensitivity can vary in the same person under
different circumstances). EFSA has reviewed the 12 allergenic foods
currently listed in Annex IIIa of Directive 2003/89/EC in terms of
what is known about the amounts of allergen needed to trigger
adverse reactions and also possible detection methods (see
www.efsa.eu.int/science/nda/nda_opinions/catindex_en.html).
However, the scientific literature is not yet sufficient to draw firm
conclusions regarding the highest dose that would not cause an
adverse effect.
how common adverse reactions are to that particular food in the

population to which it will be marketed (see Appendix I). For
example, celery and mustard allergy are not common in the UK but
are much more prevalent in eastern Europe, and fish allergy is more
prevalent in Scandinavian countries than in the UK. However, it
should be borne in mind that people from high prevalence areas may
travel to low prevalence areas where the product is sold and that
some food may not be consumed at the intended destination;
whether there are particular subgroups of the population likely to be

at particular risk, such as babies and young children (although allergy
to egg and milk is relatively common in babies and young children,
the allergy is often outgrown by the time the child reaches school
age) or those who restrict their food choices to specialist ranges for
dietary, religious or other reasons;
the relative allergenicity of the particular ingredient being used. For

example, possible cross-contamination with refined nut oils which
are highly processed ingredients, is likely to pose a lower risk than
cross-contamination with either whole, or pieces of, nut. Also, if the
product has been processed, it may not have any protein present and
therefore will not present an allergen cross-contamination risk. It
should be noted that some processed products that contain little or
no protein have not been submitted for temporary exemption from
the requirements of Directive 2003/89/EC but do not represent a risk;
and
the physical nature of the particular ingredients being used and the
geography of the manufacturing environment. The physical form of
the allergen is important, for example a liquid and a powder
represent different types of risk. Milk powder may represent a greater
risk in situations where air-borne contamination of products is
possible, but liquid milk may be of less concern if there was sufficient
separation (for example, by physical barriers, distance, timing or
cleaning) between the products in which it is deliberately used and
those where it is not.
The second step in the risk assessment process will identify the
probability of unintentional presence of allergens, by thinking about how
cross-contamination could happen and how likely it is to happen (see
figure 2).

The outcome of the initial risk assessment will be either:

Probable
A likely chance of risks occurring.
Remote
Risks are unlikely to arise but are still possible. Low

probability risks should not be ignored and should be
managed and eliminated where appropriate.
13
3.2 Allergen Risk Management

Where a risk has been identified (as either probable or remote), attempts
can be made to reduce the unintentional presence of allergens in the
product as far as possible.
Whether manufacturing individual ingredients or complex food products,
consistency in risk assessment and application of risk management
measures is needed.
The visually and physically clean standard can in principle be applied to
each stage in the supply chain.
For example, primary agricultural produce with risk of crosscontamination in the field could be assessed using a visual inspection
standard where representative samples are confirmed as visually and
physically clean from contaminating allergenic materials.
3.2.1 General Principles
Allergens should be managed to avoid their unintentional presence in
products wherever possible. This management involves evaluation of the
likelihood of allergen cross-contamination associated with every step of
the food production process, from sourcing raw materials through to
marketing of a finished product.
Food businesses generally already have Good Manufacturing Practice
(GMP) in place. These require a commitment and discipline to ensure
products meet food safety, quality and legal requirements, using
appropriate manufacturing operations, including effective food safety
systems (using hazard analysis principles) and quality assurance systems.
Existing GMP controls will assist with allergen management, for example
avoiding cross-contamination by segregation, cleaning, using separate
utensils etc. However, it should be noted that unlike microbiological risks,
heating does not necessarily destroy food allergens and may actually
increase their potency, for example roasting peanuts.
The introduction of allergen management into a food business can be
seen as an extension of existing food safety management rather than a
completely new system.
3.2.2 Manufacturing
The key aspects of food and drink manufacturing businesses to be
considered in the management of allergens are illustrated in figure 3,
which are then discussed in more detail in the following sections.

People
All staff (including temporary staff and contractors) involved in handling
ingredients, equipment, utensils, packaging and products should be aware
of food allergens and the consequences of their ingestion by sensitive
individuals. They should be trained in avoiding cross-contamination of
foods by the major food allergens. Appropriate procedures on the
management of allergens should also be available and/or posted
wherever they need to be observed in pursuit of the companys
management policy. Additionally, it is important to ensure awareness of
these procedures on the part of both workers and visitors by posting in
the reception and production areas at least a summary of the critical
aspects. Training and awareness procedures should include:
Recognising which ingredients are the allergens of concern and why.
Identifying potential allergen cross-contamination situations.
Hand washing.
Clothing requirements including laundering.
Re-work procedures.
15
Waste management procedures.
Cleaning procedures.
Dedicated equipment if available.
People movement around the site, for example, people changing

production line or site, trips to the canteen and visitors.
Equipment movement around the site, for example, maintenance

tools, food trays, etc.
Manufacturers should be aware of people moving freely between

production lines and plants, potentially transferring allergens on their
clothing or hands. There may also be an allergen cross-contamination
hazard in communal areas such as canteens and locker rooms.
Raw Materials and Supply Chain
Food businesses should establish an appropriate and proportionate
policy for assessing the allergen status of ingredients for use within their
own manufacturing processes and premises, and if appropriate, for
assessing those ingredients used by their suppliers or co-packers. Any
change in supplier should be accompanied by the appropriate checks.
Manufacturers need to be aware of the presence of the major allergens
in all raw materials, particularly the potential for allergen crosscontamination from manufacturing and handling activities on the raw
material suppliers sites, as well as earlier in the food chain during
harvesting and transport. This may be through audits or from asking
suppliers to provide the required information. Manufacturers should
ensure that materials are ordered against a clear specification and that
they ask appropriate questions of their suppliers.
A business may wish to ask its suppliers whether an ingredient contains
any food allergens either as:
a) a major component (for example, textured vegetable protein from
soya),
b) a minor component (for example, as a food additive or processing aid
which has been derived from an allergenic source like amylase from
wheat), or
c) due to food allergen cross-contamination (for example, chickpea
flour from a mill which also mills wheat).
Raw material suppliers (and their agents) should be aware of the hazards
arising from contamination by food allergens and conform to the
manufacturers purchase specification. However, commodity raw material
16
suppliers should only use allergen warning statements on products after

they have carried out an assessment of the risk of cross-contamination,
otherwise it may cause unnecessary advisory warning labelling on
finished products.
Ingredients should be fully described in specifications, for example not
using general terms such as vegetable oils and fats where those allergens
listed in Annex IIIa of Directive 2003/89/EC are concerned.
Steps should be taken to ensure that non-allergenic ingredients do not
come into contact with allergens in subsequent handling and storage (see
section on cleaning on page 22). Allergenic raw materials should be stored
in clearly identified areas where possible, for example, using colour-coded
boxes or demarcation of storage areas using painted lines on the floor.
Where allergenic raw materials are de-bagged or de-boxed, they should
if possible, be placed in dedicated lidded and labelled containers and
made easily identifiable. Such containers should only be used for storage
of other raw materials after appropriate cleaning.
If allergenic ingredients are sieved, then the sieving unit should be either:
(i)
dedicated or
(ii) thoroughly cleaned after sieving allergenic ingredients.

If possible, allergenic ingredients should be sieved after all other raw
ingredients have been sieved for the day.
In summary, practices should ensure that the allergen status of all
ingredients (including flavourings, additives, carriers and processing aids),
as well as other materials that might come into contact with the food
such as baking release agents, are known:
Check the allergen status of all ingredients with suppliers and

review regularly.
Ask suppliers to notify changes in the allergen status of the

materials they supply.
Clearly identify allergenic raw materials and segregate where

possible.
Ensure the handling of allergenic ingredients does not cause

contamination of other ingredients.
Check implications of any change of ingredient supplier.
17
Manufacturing Premises, Equipment and Processes

Whilst the ideal approach to avoiding cross-contamination with allergens
is to dedicate production facilities to specific allergenic products, it is
recognised that food manufacturing premises and product ranges vary
greatly and that this is not always an option particularly in small and
micro businesses. Where dedicated production facilities are not possible,
there are a number of ways of separating the production of allergencontaining products from those that do not contain the allergen. These
can include separation:
In different parts of the production area.
By using physical barriers between the production lines.
By use of dedicated equipment.
By minimising unnecessary movement of materials.
By appropriate scheduling of production runs, including appropriate

cleaning of equipment between production runs.
By managing re-work, ensuring that residual material containing an

allergen is not re-worked into a product not containing the allergen.
By separating the air supply, where this is practical.
Shared Equipment
It is recommended that, where practically possible, consideration is given
to the dedication of equipment within production facilities. For example,
weighing equipment, scoops and utensils could be dedicated and the
weighed product placed in dedicated, lidded and labelled containers.
Consideration could be given to colour coding equipment, although this
may not be practical where a number of allergens are being handled,
and/or colour coding is used already for other purposes, such as the
identification of cooked or raw ingredients, or vegetarian products.
If it is possible to dedicate areas or equipment, it is important to avoid
allergen cross-contamination between these and other operations,
including managing the movement of equipment, personnel, vehicles and
maintenance tools.
Physical Separation
Physical separation should be considered for high risk ingredients (such
as milk in baby foods) and the implications of changes to the layout of
the food production area should be assessed. Consideration should also
be given to the ease of cleaning of equipment. Avoiding the crossover of
production lines and allowing adequate space for effective cleaning will
help minimise the risk of allergen cross-contamination.
18
Airborne Particles in Manufacturing Area

It is recommended that, wherever practically possible, consideration
should be given to the implications of air movement. For example, where
nut products and nut free products are produced in the same production
area it may be possible to dedicate air conditioning/extraction fan
systems to contain nut dust, or positive pressure may be used in nut free
rooms to prevent nut traces entering the room on the air.
When scheduling production runs consideration should be given to
scheduling those products not containing the allergenic ingredient first.
Additionally, long runs of allergenic products should be undertaken
wherever possible, to minimise changeovers and these should be
followed by a major clean down.
Storage
Consideration should be given to the temporary labelling of work in
progress. This is, for instance, a half-finished product that is held-over.
Care should be taken that the product is not mistaken for another
product with a different set of allergens.
Similarly, care should be taken to label and store packaging materials that
are unused at the end of a production run.
Co-products are misshapes and broken products, which for quality
reasons are not acceptable as finished product but could still be
consumed by employees or sold through factory shops. Such products
should be subject to the normal allergen labelling controls.
Re-work
Re-work that contains allergenic ingredients should be re-worked only
into products that contain that allergen, for example chocolate that
contains nuts or nut fillings should only be re-worked into other nutcontaining chocolates. Re-work should be clearly identified in order that
it may be tracked in the manufacturing process.
Oils used for cooking allergenic foods (for example, shellfish, fish and
breaded or battered products) should not be used subsequently for
cooking products not containing that allergen.
In summary
Is it possible to have dedicated production lines or areas?
Is it possible to erect physical barriers between production lines or

areas?
Is it possible to dedicate utensils and equipment?
Is it possible to clean between production runs?
Is it possible to schedule production runs to minimise possible

cross-contamination?
19
Is re-work managed?
Is it possible to manage airflow?
Are held-over products suitably labelled?
Is there a procedure for removing packaging and labelling it before

returning it to the stores?
Cleaning
Very small amounts of some allergens, such as nuts, can cause adverse
reactions, including potentially fatal anaphylactic shock. Therefore,
thorough cleaning that is effective in reducing the risks of allergen crosscontamination should be used where appropriate. A visually and
physically clean standard is not just a casual visual inspection of the
production line or area, it also requires that all of the trouble spots are
sought out and inspected. Cleaning practices that are satisfactory for
hygiene purposes may not be adequate for removing some allergens and
their validity for such a purpose should be assessed, for example, via
residue/environmental swab testing (see Appendix IV on testing).
Equipment may need to be dismantled and manually cleaned to ensure
hard to clean areas are free from allergen residues. Particular food
materials (for example, powders, seeds, pastes and particulates) present
significant cleaning problems and any relevant industry guidance, where
this has been developed, should be followed. Adequate procedures
should be in place for cleaning both production and packaging
machinery. Where adequate cleaning is not possible, then the risk of
allergen cross-contamination should be assessed and advisory labelling
used, if appropriate.
Care is needed in cleaning to ensure that the cleaning of one line does
not contaminate another (for example, by use of compressed air
cleaning), or an area which has already been cleaned (for example, clean
dry mix areas from the top down).
Any spillage that occurs during production, storage and transportation
should be cleaned up immediately to ensure that there is no subsequent
allergen cross-contamination. Where known allergen contamination has
occurred, the contaminated material should be labelled and physically
moved away from the non-contaminated ingredients and work-in-progress.
Consideration should be given to maintenance activities, such as the use
of dedicated tools or adequate cleaning procedures where tools are not
dedicated.
Where adherence to a cleaning regime is part of a separation system, it
should be validated as fit for purpose and compliance should be monitored.
20
Investment in developing and following appropriate cleaning regimes will

help to minimise food allergen cross-contamination and can reduce the
likelihood of needing costly product recalls.Ensure that cleaning
equipment itself is cleaned after use to minimise the risk that it may carry
and transfer allergen traces.
Establish appropriate cleaning regime including laundering of

protective clothing.
Validate cleaning regimes.
Monitor that cleaning is being done properly.
Keep records of cleaning.
Packaging
Incorrect packaging and/or labelling is a major cause of allergen related
product recalls. Procedures for checking that the correct labels are
applied to products should be implemented and audited regularly, so
that accurate information is provided to allergic consumers. Checks
should be in place between processing and packing to ensure the correct
packaging is used, for example the use of automated label verification
systems.
It is important that, following recipe changes or the introduction of a
new allergen cross-contamination risk etc, the old packaging is not only
withdrawn from use but is physically destroyed, so that it cannot be used
in error.
There should be systems to ensure packaging is removed at the end of a
run, including any packaging that may be within the wrapping machine.
This will help to avoid packaging mix-ups when the product to be packed
is changed and, therefore, reduce the number of instances in which
misleading information is passed to the consumer.
It is important to ensure that the correct outer packaging is used for
multi-pack products and that allergen information appears on, or is
visible through, both the inner and outer wrappers.
New Product Development and Reformulation
Product Formulation
Whenever possible, it is good practice not to include an allergenic
ingredient in a product unless necessary. For example, manufacturers
could consider using corn (maize) flour instead of wheat flour or using
vegetable oil, for example sunflower oil, instead of butter. By using
allergenic ingredients only when they are essential components of a food
product, one element of the risk from unintentional allergenic crosscontamination will be minimised.
21
Reformulating Products
Reformulation of a product with the introduction of a new allergenic
ingredient may lead to accidental contamination of other lines produced
in the same premises, for which advisory labelling might then become
appropriate. Businesses can benefit from simplification programmes and
these might provide opportunities to discontinue minor lines that bring
allergen complexity in manufacturing, as well as reformulating products
to avoid allergenic ingredients.
Extending Brands
If it is decided to extend a brand name into a different product sector (for
example, an established confectionery product giving its name to a
dessert product or ice cream), care should be taken that the presence of
any allergen not associated with the original product is clearly indicated.
The approach to allergen labelling across a brand should be as consistent
as possible.
Factory Trials and Consumer Testing
If conducting factory trials of allergen-containing products, measures
should be taken to avoid allergen cross-contamination with existing
products. Information on the presence, or potential presence, of
allergens should be made available to those involved in factory trials and
in taste testing and that information should be clearly conveyed with
products presented for wider test and marketing purposes.
However clearly they are labelled, care should be taken if sample
products containing the major food allergens are distributed or offered
where they can be taken by unsupervised children (for example through
letterboxes, in stores or other public places).
Managing Changes
Any changes to one production process within the food production area
or the introduction of a new product line can affect the risks of allergen
cross-contamination of other products. Moving production of a product
to another site may also result in a different allergenic risk that needs to
be relayed to the consumer. Following any such changes, it will be
necessary to conduct a new assessment of the risks of allergen crosscontamination of a product, including an evaluation of any advisory
labelling that might be necessary.
22
Consumers may unknowingly consume allergen-containing products

where changes have been made to the recipe of a familiar product and
allergenic ingredients have been introduced. Any changes to the allergen
status of a product (for example, recipe changes) need to be made
obvious to the consumer, for example, by using prominent labelling
flashes, preferably on the front of the pack, in addition to the amended
ingredients list. Suitable warnings might be, for example, New Recipe
and Now Contains. It may also be possible to use other methods such
as websites to inform consumers of recipe changes. This is important, as
allergic consumers, who may have been consuming the product for some
time, need to be informed of a new potential hazard. In addition, food
manufacturers and retailers are strongly advised to provide updated
information to consumer support organisations such as the Anaphylaxis
Campaign and Coeliac UK as they have systems in place for informing
their members about changes.
The processes described in detail above are summarised in the following
figure.
23
Figure 4: Steps in the Decision Tree for Managing Allergens
STEP 1
RISK ASSESSMENT FROM INTENTIONAL PRESENCE
Is the food manufactured from any of the allergenic foods, or their

derivatives, as specified in current UK legislation (as listed in
Appendix I)?
YES
List ingredient/additive/processing aid in ingredients

declaration on pack.
GO TO STEP 7
NO
No need for on pack declaration of allergens in

ingredient list.
GO TO STEP 2
STEP 2
EXPOSURE ASSESSMENT
What is the likelihood, under normal operating conditions, of crosscontamination of the food by specified allergens from either the
ingredients used in it or the manufacturing environment in which it
is made/handled?
Definitions PROBABLE (Likely to occur)
REMOTE (Risk unlikely to arise)
NB. It is important in assessing the likelihood of allergen crosscontamination to consider all the possible sources (see figure 2) and
also the physical form and characteristics of the allergen (as fully
detailed in Step 4).
Is it PROBABLE that the ingredients in the manufactured food will be
cross-contaminated with allergens during growing, harvesting,
processing, handling or distribution or that the food is manufactured
on a production line or equipment that comes into direct contact
with allergen containing materials?
GO TO STEP 2a
Is there a REMOTE possibility that the ingredients in the
manufactured food will be cross-contaminated with allergens during
growing, harvesting, processing, handling or distribution or that the
food is manufactured on a production line or with equipment that
comes into direct contact with allergen-containing materials?
NO ADDITIONAL RISK MANAGEMENT OR ADVISORY WARNING
LABEL REQUIRED.
GO TO STEP 7
24
STEP 2a
CHECK AGAINST INGREDIENT LABELLING
Is the potential cross-contaminating allergenic food already

declared on the label/ingredients list?
YES NO ADDITIONAL RISK MANAGEMENT OR ADVISORY
WARNING LABEL REQUIRED.
GO TO STEP 7
NO GO TO STEP 3
STEP 3
CHECK AGAINST EXEMPTIONS LIST
Is the potentially cross-contaminating material exempt from

mandatory labelling (for instance, an allergenic derivative officially
exempt in legislation from mandatory labelling (see Appendix I))?
GO TO STEP 7
NO GO TO STEP 4
STEP 4
HAZARD CHARACTERISATION
Identify physical form and characteristics of the potentially crosscontaminating allergenic material
Protein: Is the material highly refined (no protein present)?
Physical form: liquid/powder/particulate
Distribution of contamination: homogenous or particles (lumps,
pieces, seeds).
GO TO STEP 5
25
STEP 5
RISK MANAGEMENT OF UNINTENTIONAL PRESENCE
Can this identified risk of cross-contamination be reduced or

eliminated?
a) For highly refined and/or processed materials with little or no
allergenic protein
As the allergenic protein is the trigger for adverse reactions in
sensitive individuals, evidence of little or no allergenic protein
present indicates effective protection against adverse reactions in
sensitive individuals.
YES NO RISK MANAGEMENT OR ADVISORY WARNING LABEL
REQUIRED.
GO TO STEP 7
b) For liquid or powdered materials with homogenous
distribution
Working to GMP and Good Agricultural Practice with HACCP
controls, including a visually and physically clean inspection (or
allergen testing methods if preferred), combined with appropriate
segregation measures should minimise the risk of crosscontamination.
GO TO STEP 7
c) For particles or powdered materials with heterogeneous
distribution
It can be difficult to manage and ensure removal of particles or
powdered materials from shared equipment/environment.
Therefore, unless:
There is clear demonstrable evidence of a visually and

physically clean or equivalent standard, or
Assessment of the end product as consumed indicates little or

no allergenic protein remains, a risk of cross-contamination
remains.
NO ADVISORY WARNING LABEL REQUIRED

GO TO STEP 6
Cross-contamination by small pieces of allergenic foods such as
peanuts, tree nuts and sesame seeds can be exceptionally difficult
to manage and therefore may warrant additional consideration for
use of advisory labelling.
26
STEP 6
RISK COMMUNICATION
Refer to section 3.3 Allergen risk communication.

GO TO STEP 7
STEP 7
CHECK OTHER RELEVANT ALLERGENS REPEAT STEPS
Have all relevant allergens been considered? Is it certain that no

other allergen could have cross-contaminated your product?
YES NO FURTHER ACTION REQUIRED
NO GO BACK TO STEP 1 AND REPEAT PROCESS UNTIL ALL
RELEVANT ALLERGENS HAVE BEEN CONSIDERED
A number of theoretical worked examples using this process can be

found in Appendix III.
3.3 Allergen Risk Communication

Following completion of the risk assessment (as set out in section 3.1) and
elimination or reduction of the risks where possible, a decision on
whether or not advisory labelling is appropriate then needs to be made.
This section gives advice on how to provide allergen cross-contamination
information to the consumer.
3.3.1 Advisory Labelling
When communicating with allergic consumers through labelling, point of
sale information, leaflets and websites, consumers should be advised
always to refer to the ingredients list, and the labelling generally, for
detailed information about the composition of the product and the
presence of particular allergens.
Any advisory labelling should be in close proximity to the ingredients list.
It is recommended that there is a clear distinction in the labelling
information provided between ingredients that are deliberate
components of the food (whatever the level of incorporation) and any
possible allergen cross-contamination arising from production of the raw
ingredients or during the manufacture or transport of the food. List of
ingredients should include only ingredients deliberately added to the
product. The practice of including possible contaminants in the
ingredients list (so called last ingredient listing) is illegal under Section
15(1)(a) of The Food Safety Act 1990 (Article 14(1)(a) of The Food Safety
(Northern Ireland) Order 1991) and possible allergen cross-contaminants
should be declared separately.
27
However, information on deliberate ingredients and possible

contaminants should be adjacent to each other and in the same field of
vision as the ingredients list.
The presence of deliberately added allergenic ingredients, and/or advice
on the possible presence of allergen cross-contamination, may
additionally be indicated by means of an allergy information/advice
panel. These panels are not a legal requirement but, where such
information is given, it is best practice to associate it clearly with the
ingredients list. If such devices are employed, all allergenic foods or
ingredients as defined by law and used in the food should be listed in
such a box, panel or statement. If using a box headed, for example,
Allergy Advice, make sure that there is a clear distinction between
allergens that are deliberate ingredients and those that are possible
cross-contaminants. An example of how this may be done is given below,
but other formats for the box or statement may be used:
INGREDIENTS
CONTAINS
Wheatflour, Sugar,
Vegetable Oil, Barley Malt
Extract, Salt, Raising Agent:
Sodium Bicarbonate, E503,
E450, Glucose Syrup
Wheat, Barley, Gluten

MAY CONTAIN
Nuts
Advisory labelling on possible cross-contamination with allergens should

be justifiable only on the basis of a risk assessment applied to a
responsibly managed operation. Warning labels should only be used
where there is a demonstrable and significant risk of allergen crosscontamination, and they should not be used as a substitute for Good
Manufacturing Practices.
The use of detailed explanations of the mechanisms by which
contamination occurs (made on a line that also handles allergen X or
made in a factory that also handles allergen X) may be confusing to
consumers who do not have experience of food manufacturing
conditions, separation techniques and cleaning procedures. Such
consumers could therefore either ignore or incorrectly interpret such
statements in terms of the risk of allergen cross-contamination that they
represent. Consumer research conducted in 2002 demonstrated that
most consumers wanted clear and consistent statements about what
they could and could not eat, with the same phrases used by all
manufacturers and retailers 5.
28
Nut Allergy Labelling Report of Research into the Consumer Response, 2002. Creative
Research/COI Communication
However, in a recent consultation on possible phrases to be used to

convey allergen advisory information there was a significant proportion
of respondents who did not like phrases such as Not suitable for or
Not recommended for (http://www.food.gov.uk/multimedia/pdfs/
maycontainconsummary.pdf). Such consumers preferred to be presented
with the facts, which would allow them to make their own decision on
whether or not to eat the food. Some manufacturers agreed with this,
not wishing to make medical judgements for individuals, while others
preferred to make a suitability statement, believing that it is difficult to
communicate the risk-based approach behind using an allergen advisory
statement.
Either way, consumers need to be told about the potential risk in a
simple, consistent way. It is suggested that a brief, factual phrase is used
to communicate the risk and this will also be easily translatable into
other languages. For example:
may contain X
not suitable for someone with X allergy
A number of illustrative examples of particular products and situations

where advisory labelling is and is not appropriate are given in Appendix III.
Effective Labelling Messages
In the past advisory labels have tended to use the word nuts without
specifying the particular type of nut involved. Whilst this may be
justifiable in certain situations where mixed or multiple nut ingredients
are used or are supplied by the same suppliers, this may not always be
the case. It is known that some people are only allergic to peanuts and
others are only allergic to tree nuts, and sometimes only to specific tree
nuts. Consideration should therefore be given to whether it is possible on
the label to indicate the species of nut involved. Similarly, where a
product contains peanuts but may be cross-contaminated with tree nuts,
it may be appropriate to use a phrase such as May Contain Other Nuts.
If an allergenic food, or a derived ingredient, is listed in the ingredients list
it is not necessary to additionally provide allergen advisory labelling for
possible cross-contamination with the same source allergenic food. For
example, if an Indian-style ready meal contained peanuts, it would not be
necessary to use warning labelling that some of the ingredients used in
the sauce may contain peanuts.
Advisory statements need to be easily visible and clearly legible. Fonts
should be simple. See the FSA Clear Labelling Guidance
(http://www.food.gov.uk/multimedia/pdfs/clearlabelling.pdf) for general
advice.
29
3.3.2 Allergen-free foods

A growing number of food manufacturers and retailers are providing
ranges of substitute foods made without certain common allergenic
foods, such as milk, egg or cereals containing gluten. In addition, some
manufacturers choose to exclude certain allergens from a site. It should
not be assumed that the lack of a need to use advisory allergen warnings
entitles a product to make a Free From or made in allergen X free
factory claim. Consumers are likely to actively seek such products if they
need to avoid particular ingredients and it is essential that any such
claims are based on specific, rigorous controls to ensure their validity.
If manufacturers produce lists of foods free from particular allergens,
these should be regularly reviewed and updated.
An allergen-free claim is an absolute claim, which may be interpreted by
consumers to mean a complete absence, whereas the best that can be
scientifically demonstrated at present, is that samples of the food were
shown to be below the analytical limit of detection of a testing method
on one or more occasions. However, when there is general agreement on
the management action levels below which adverse reactions are
unlikely to be triggered, appropriate limits for claiming that a product is
free from a particular allergen can be set.
Standards for Gluten Free
Currently there are no established legal standards for any residual levels
of allergens in products labelled as Free-from those allergens. However,
there are some international standards for gluten free products (see
Appendix I).
3.4 Allergen Risk Review

Allergen Management Systems should be monitored and reviewed to
provide assurance that they are working correctly. The most effective
way of doing this is by carrying out routine checks on manufacturing
operations including an audit or health check of the system. An overall
health check can find any weaknesses in the system and then corrective
actions can be taken. A key benefit of auditing the system is to provide
evidence of due diligence in managing allergens.
The health check should as a minimum encompass compliance with
GMP requirements, including:
30
Review and verification of the hazard analysis and hazard

management system.
Product and ingredient specifications.
Operating procedures.
Cleaning procedures.
Training records demonstration of competence.
Analysis of customer complaints.
Customer complaints should be investigated and changes made where

necessary.
The frequency of review will depend on the risk level of the operation.
An annual review is likely to be reasonable in most circumstances.
However, any of the following may trigger the need to conduct a review:
Introduction of new ingredients, new recipes or new processes,
Changes in scheduling, equipment, site, source of raw material,

product storage, handling or manufacture,
EFSA will be reviewing the list of allergens for mandatory ingredients

listing, so new allergens may emerge that will need to be managed, or
Any other changes which introduce significant risks.
For example, any changes to one process within a food production area,
or introduction of a new product, can affect the risks of allergen crosscontamination of other products manufactured at the same site. Moving
production of a product to another site may also result in a different
allergenic risk, which needs to be relayed to the consumer.
Following any such changes, it will be necessary to conduct a new
assessment of the risks of allergen cross-contamination of a product,
including an evaluation of any advisory labelling that might be necessary.
31
Appendix I: Allergen Prevalence and

Severity
This Appendix lists the allergens in Annex IIIa of Directive 2003/89/EC
that have to be labelled when used as ingredients, and includes
information on the severity of allergic reactions to these foods and how
common they are. It also lists the main derivatives of these allergenic
foods that may be used in food manufacture.
Ingredients derived from micro-organisms fermented on allergenic
source materials such as cereals, are not covered by the labelling
requirements of this Directive.
At present there is a lack of scientific and clinical evidence on which to
base firm conclusions regarding the minimum amounts of some allergens
needed to trigger adverse reactions in sensitive individuals. The available
evidence was evaluated by the European Food Safety Authority in 2004
and by the US Food and Drug Administration in 2005. Collaborative work
to establish agreed management action levels for the most significant
food allergens is currently underway.6
In the absence of thresholds, a qualitative approach to managing
allergens should be applied and a number of factors considered. These
factors are outlined in section 3.2. The following table should be used to
feed into the risk assessment process.
32
For example, the US Food and Drug Administration draft report on Approaches to Establish
Thresholds for Major Food Allergens and for Gluten in Food, that was issued for consultation in
June 2005 and the Food Allergy Research and Resource Programme Scientific Roundtable on
Thresholds in October 2004. ILSI Europe Newsletter, June 2005, pg.10-12.
Table of allergens
Allergen
Prevalence and severity
Some derivatives and foods

made with this allergen that
can trigger allergic reactions
Cereals containing
gluten (wheat, rye,
barley, oats, spelt,
kamut or their
hybridised strains) 7
Coeliac disease or intolerance

to gluten is a reaction to the
protein gluten found in
cereals like wheat, barley and
rye. A protein of similar
structure is also found in oats
and can cause similar
problems. A recent study
suggests that based on blood
tests, the prevalence of
coeliac disease is about 1% of
the UK population.
Cereals can also cause food

allergy, although this is not
common in the general
population. Cereal allergens
can cross-react with pollen
allergens.
Flour
Starches
Bran
Rusk
Bread, breadcrumbs
Semolina
Cous cous
Hydrolysed vegetable
protein (if made from
wheat)
*Note: Wheat based glucose

syrups including dextrose,
glucose syrups based on
barley, wheat based
maltodextrins, and cereals
used in distillates for spirits are
unlikely to trigger allergic
reactions in allergic people or
intolerance in those with
coeliac disease.
Derivatives
of these
ingredients are also exempt.
There is a Codex Alimentarius Standard for Gluten Free Products which is based on analysis of the nitrogen content of
gluten-containing cereals and this permits a maximum of 200 parts per million (ppm or mg/kg) gluten in the finished product
and allows for a cereal-derived product to be labelled gluten free if it does not exceed that limit. This Codex standard does
not apply to products that are made from ingredients that naturally do not contain gluten, where there is a proposal for a
maximum of 20ppm (mg/kg). The 200ppm limit also applies to food that are mixes of gluten-containing and non-gluten
containing cereals.
33
Allergen

Crustaceans
(includes all species
of crustaceans, e.g.
lobster, crab, prawns
and langoustine)
Allergy to crustacea is quite

common. People who are
sensitive can react to different
types of crustacean, e.g.
shrimps, prawns and lobsters.
Chitosan
Shrimp paste
Crustacea often cause severe

reactions, and some people
can react to cooking vapours.
Some people allergic to
crustacea also react to
molluscs.8
Eggs
Egg allergy is common in young

children, but more than half
the children affected grow out
of this allergy by age 3. Egg can
cause anaphylactic reactions in
some individuals.
Egg powder, dried egg or

pasteurised egg
Albumin
Egg glaze
Mayonnaise
*Note: Lysozym (produced
from egg) used in wine, and
albumin (produced from egg)
used as fining agent in wine
and cider are unlikely to
trigger adverse reactions.
However, Lysozym used for
other purposes may trigger
adverse reactions.
34
Although molluscs are known to cause allergic reactions in those who are susceptible, they are not currently included in the
list of specified allergens. The European Commission has agreed to reconsider this issue.
Allergen

Fish
Fish allergy is more common

in adults than in children but it
can often be severe, and
frequently causes anaphylaxis.
All the major fish allergens

cross-react in terms of their
allergenicity and no fish is safe
for fish allergic patients.
Fish (all species)

Fish extracts
Fish sauce
Fish oils
Fish paste
Worcester sauce (some
brands)
Omega-3 rich oils derived
from fish.
*Note: Fish Gelatine used as a
carrier for vitamins and
flavours, and fish gelatine and
Isinglass used as fining agent in
beer, wine and cider are
unlikely to trigger allergic
reactions. However, other uses
of fish gelatine that may result
in higher levels being present in
the food as consumed are not
exempt as such doses may be
sufficient to trigger allergic
reactions.
35
Allergen

Peanut
Peanuts (also known as

groundnuts and monkey nuts)
are a common cause of food
allergy, affecting 1-2% of the
UK population. They can cause
severe, anaphylactic reactions,
and are the most common
cause of fatal food allergy.
Peanut allergy is commonly
acquired in childhood and
seldom resolves with age.
Unrefined, cold-pressed
peanut oil (sometimes
known as arachis oil)
Peanut butter
Peanut flour
Various peanut protein
products
Satay sauce
Refined peanut oil (this has
not been exempted from
the requirement to label as
an allergen under EU
Directive 2003/89/EC,
although according to
researchers9, most peanut
allergic consumers do not
react to it).
A significant proportion of
people with peanut allergy
also react to tree nuts, and
there is also allergenic crossreactivity with other members
of the legume family, such as
soya and lupin.
Heat treatment, especially
roasting, increases the
allergenicity of peanuts.

Allergen

Soy(a)
Soya allergy is more common

in young children but children
often grow out of soya allergy
by 2 years of age. Adults are
occasionally affected.
Symptoms are usually mild
and anaphylactic reactions
occur rarely.
Allergenic cross-reactivity
between soya and other
legumes, including peanut, is
possible and there are some
reports of cross-reactivity
between soya and cows milk.

tocopherols (E306), natural Dalpha tocopherol, natural Dalpha tocopherol acetate,
natural D-alpha tocopherol
succinate from soybean
sources, vegetable oil-derived
phytosterols and phytosterol
esters from soybean sources
and plant stanol ester
produced from vegetable oil
sterols from soybean sources
are unlikely to trigger allergic
reactions.
37
Allergen

Milk
Cows milk allergy is the most

common food allergy in young
children and affects 2 7% of
babies under one year of age.
About 87% of children grow
out of milk allergy by age 3.
There is a high degree of crossreactivity between cows milk

and milk of other mammals
such as sheep, goats and
buffalo.
Symptoms are often mild but
milk can cause anaphylactic
reactions in some individuals.
Some people cannot tolerate
milk because they lack the
enzyme that breaks down
lactose, the sugar found in
milk. Milk from mammals
including cows, goats and
sheep all contain lactose and
so goats milk and sheeps milk
are not suitable alternatives to
cows milk for people who are
intolerant to lactose.
38
Whey
Caseinates
Milk powder
Lactose
Butter, cheese, cream,
yoghurt, ghee
*Note: Whey used in

distillates for spirits, milk
(casein) products used as
fining agents in cider and
wines and lactitol are unlikely
to trigger allergic reactions.

*Note: Nuts used in distillates
for spirits, and nuts (almonds
and walnuts) used (as flavours)
in spirits are unlikely to trigger
allergic reactions.

Celery and Celeriac
Celery is a common cause of

oral allergy syndrome
amongst adults in mainland
Europe, where allergy to
celeriac is also common.
Symptoms range from mild to
severe (anaphylaxis). However,
allergies to celery and celeriac
are not common in the UK.
Celery powder
Celery seeds
Celariac powder
Mustard allergy is not

common in the UK. However,
it is more common in France
where it has been reported to

Note
*Some ingredients derived from the source allergenic foods are
sufficiently processed so as to remove protein and are thus unlikely to
trigger allergic reaction in sensitive individuals. The European
Commission has produced a list of such derived ingredients that are
exempt from the labelling requirements of Directive 2003/89/EC this is
to be found in Commission Directive 2005/26/EC. This list is based on
advice from EFSA who rejected some of the ingredients proposed for
exemption see www.efsa.eu.int/science/nda/nda_opinions/catindex_en.html

Appendix II: Legal Considerations of

Allergen Cross-Contamination
There are both criminal and civil legal regimes relevant to the sale of
foods containing allergens and the provision of allergen-free lists10. It is
essential that these are given careful consideration. The following is a
brief outline of the main provisions to assist manufacturers in identifying
their legal obligations and the appropriate courses of action in respect of
Good Manufacturing Practice and the provision of information to, or for
communication to, consumers.
Manufacturers should seek their own legal advice as appropriate.

The Food Labelling (Amendment) (England) (No. 2) Regulations 200411
implement Directive 2003/89/EC of the European Parliament and the
Council of 10 November 2003, which amends Directive 2000/13/EC as
regards indication of ingredients present in foodstuffs. The Regulations
for England and the equivalent Regulations in Scotland and Wales, amend
the Food Labelling Regulations 1996, (as amended)12. Sale of products that
did not comply with the new rules were prohibited from 25 November
2005, but products that were labelled before that date could be sold
while stocks lasted. The provisions in this legislation do not relate to
foods sold loose or non-prepacked or those prepacked for direct
sales (see guidance notes at www.food.gov.uk/multimedia/pdfs/
labelamendguid25nov05.pdf).
The Food Labelling (Amendment) (England) (No. 2) Regulations 200513,
which implements Directives 2005/26/EC and 2005/63/EC14, exempts
various ingredients derived from the listed allergenic foods from
the labelling requirements of Directive 2003/89/EC. Separate but

These legal provisions are correct at the date the document was drafted but may be subject to
amendment.
Scotland, Wales and Northern Ireland have equivalent Statutory Instruments to implement the
Directive.
Equivalent Regulations in Northern Ireland amend the Food Labelling Regulations (NI) 1996 (as
amended).
These Regulations are amended by [S.I. 2005/2969] The Food Labelling (Amendment) (England)
(No. 2) Regulations 2005 and in N. Ireland by [S.R. No. 475/2005] Food Labelling (Amendment No.

The Food Labelling Amendment (Scotland) (No. 3) Regulations 2005 implement these Directives
in Scotland.
parallellegislation applies in respect of Scotland and Northern Ireland

and Wales, as indicated below. (See guidance notes at
http://www.food.gov.uk/mulimedia/pdfs/labelguidederived.pdf and on
the N. Ireland web page http://www.food.gov.uk/northernireland/
niregulation/niguidancenotes/foodlabel).
The above Regulations do not cover accidental cross-contamination of a
product with the listed allergenic foods or food ingredients. There is other
law which may be applicable to possible allergen cross-contamination of
foods that do not deliberately contain one of the EC listed foods, or their
derivatives, with that allergenic food.
Article 14 of EC Regulation 178/2002 (General Food Law Regulation)
This provision applied from January 2005. Paragraph (1) prohibits unsafe
food from being placed on the market. For the purposes of the
Regulation, placing on the market means the holding of food for the
purpose of sale, including offering for sale or any other form of transfer,
whether free of charge or not, and the sale, distribution, and other forms
of transfer themselves. Food is deemed to be unsafe if it is injurious to
health or unfit for human consumption, and Article 14 contains provisions
for determining whether food falls within this prohibition.
Paragraphs (3) and (4) of this article are particularly relevant:
3. In determining whether any food is unsafe, regard shall be had:
a)
to the normal conditions of use of the food by the

consumer and at each stage of production, processing and
distribution, and
b)
to the information provided to the consumer, including

information on the label, or other information generally
available to the consumer concerning the avoidance of
specific adverse health effects from a particular food or
category of foods.
4. In determining whether any food is injurious to health, regard

shall be had:
a)
not only to the probable immediate and/or short-term

and/or long-term effects of that food on the health of a
person consuming it, but also on subsequent generations;
b)
to the probable cumulative toxic effects;
c)
to the particular health sensitivities of a specific category

of consumers where the food is intended for that category
of consumers.
43
Various criteria, have to be considered, including information provided to

the consumer concerning the avoidance of specific adverse health
effects from a particular food or category of foods (see Article 14(3)(b));
and also the particular health sensitivities of a specific category of
consumers where the food is specifically intended for that category of
persons (see Article 14(4)(c)). In the allergy context, this refers particularly
to foods sold as free from certain allergens or suitable for people with
particular health needs (for example, those people who have coeliac
disease). (See section 3.3.2).
Article 16 of EC Regulation 178/2002 (General Food Law Regulation)
This article requires that the labelling, advertising and presentation of
food, including the information made available, should not mislead
consumers.
These articles are enforced in Great Britain by means of the General Food
Regulations No. 3279/2004. Equivalent regulations apply in Northern
Ireland15.
Section 14 of the Food Safety Act 1990
(Article 13 of the Food Safety (NI) Order 1991)
This provision makes it an offence for anyone to sell to the purchasers
prejudice, any food which is not of the nature, substance or quality
demanded by the purchaser.
Section 15 of the Food Safety Act 1990
(Article 14 of the Food Safety (NI) Order 1991)
This provision makes it an offence to falsely describe or present food.
More particularly, it is an offence for food labelling to be false or likely
to mislead as to the nature, substance or quality of the food. The section
also applies in relation to the advertising and presentation of food.
It remains widely accepted that individuals who have allergic reactions to
certain foods owe themselves a particular duty of care to scrutinise food
labels more closely than an average consumer does.
Directive 89/398/EEC and subsequent Directives on foods for
particular nutritional uses (PARNUTS foods)
Any foods that are sold for particular nutritional uses will also need to
meet the requirements of the relevant legislation.

General Food Regulations (NI) 2004 SR. No. 505/2004.
Enforcement
It should be noted that the criminal legislation is enforced through local
enforcement authorities. It would be prudent for manufacturers to
advise their local officers of the management measures they have
adopted, to obtain advice on the adequacy of the measures and to
increase the likelihood of the acceptability of such measures as
constituting a defence of due diligence should the need arise. Ultimately,
however, in the event of a prosecution the adequacy of a manufacturers
due diligence procedures would be a matter for the Courts.
CIVIL LAW
In addition to the criminal regime, liability can also arise at civil law under
the product liability provisions of the Consumer Protection Act 1987 or
under the common law of negligence.
Consumer Protection Act 1987
Under the Consumer Protection Act 1987 (CPA) a manufacturer can be
held liable to consumers for injury, loss or damage suffered as a result of
his supplying a defective product16, whether or not he is negligent.
Negligence
In negligence, it is well established that manufacturers owe a duty of care
to their consumers to supply safe products. In order to discharge their
duty satisfactorily they are required to take all the steps a reasonable
manufacturer in the same circumstances would have taken to ensure the
safety of his products.
Labelling Implications
A manufacturers position under the Consumer Protection Act 1987 for
supplying a defective product and under the rules of negligence will vary
in different circumstances and may or may not be affected by advisory
notices.
Unintentional Presence
Allergens that are, or may be, unintentionally present in products will
not, of course, be labelled as ingredients.
Under the Consumer Protection Act 1987, a product unintentionally
cross-contaminated with an allergen may be defective especially when
the presence is outside the specification. The question then arises as to
whether or not advice about the possible presence of the allergen will
16
A defective product is defined as one where the safety of the product is not such as persons
generally are entitled to expect. Criteria include any instructions or warnings given with the
product and what might reasonably be expected to be done with it.
45
effectively cure such a defect. The ability of such advice to cure such a
defect may depend on a number of factors, for example, the size and
prominence of the advisory statement and consumer expectation as to
the nature of the product, and would be decided on a case by case basis.
A manufacturer may be deemed to be negligent either in the
manufacture of the product or in its presentation. Where Good
Manufacturing Practices or other due diligence measures are in place,
they will go a long way to rebutting negligence in manufacture.
Nonetheless, a manufacturer could be negligent in respect of his labelling
if he fails to give advice in a situation where, despite the operation of
GMP, he should have been aware of a significant likelihood of product
contamination.
In practice, it will become more difficult for a manufacturer who does
not provide the relevant advice to establish that his product is not
defective under the Consumer Protection Act 1987 or that he is not
negligent in the labelling of his product where a significant number of
other suppliers are providing advice on the potential presence of
allergens in their products.
Consumer Redress
In civil law, individual consumers have the right to bring actions against
manufacturers directly for compensation in respect of any loss, damage
or injury they have suffered.
Allergen-Free Claims
Some food manufacturers make allergen-free claims on their products
and/or provide lists of products free from specified allergens to
consumers via leaflets, carelines and websites. Such lists should be
clearly dated and limited in time and/or scope by including a disclaimer
along the following lines:
This list is valid at time of publication/will remain valid until the end of
[x]. However, recipes may change so always check ingredients lists,
and/or contact us on [telephone number] for an up to date list or for
information about new products or variants of existing products.
Manufacturers who employ Good Manufacturing Practices reduce the
risk of cross-contamination of their food products by any allergens, and
should therefore minimise their legal liability in respect of on-pack claims
or other indications of freedom from specified allergens. However, the
provision of an incorrect list could bring such manufacturers within the
food safety and consumer protection controls detailed above and it is
thus a matter for individual companies commercial judgement to decide
whether or not such claims should be made or lists compiled. Such
advice should not be provided unless supported by an appropriately
documented quality system.
46
Appendix III: Worked Examples

For illustrative purposes, a number of situations are described below
where possible allergen cross-contamination could occur, together with
an assessment of the risk, leading to a decision on allergen advisory
labelling. These are included to help companies understand how to
approach this problem and are not intended to provide definitive advice
for individual situations. Manufacturers should work through these
examples using the allergen advisory labelling decision tree (see figures 1
and 4). Each manufacturer will need to make their own assessment of the
particular risks associated with the products that they produce.
Example 1.
Production of oven chips with sunflower oil that was

refined in premises also refining peanut oil
Step
Example
Oven chips contain refined sunflower oil as a deliberate

ingredient. There are no deliberately added allergenic foods
requiring labelling.
The supplier has declared that sunflower oil was refined in a

food production area that also refines peanut oil.
There is a probable risk of cross-contamination under normal
operating conditions between the refined sunflower oil and
refined peanut oil as they are made using shared equipment.
2a
Peanut is not already declared in the ingredients list.
Refined peanut oil is not exempt from allergen labelling when

present as an intentionally added ingredient.
The potentially cross-contaminating allergenic material is a

highly refined oil with little or no protein present.
Analysis confirms batches of peanut oil consistently do not

contain peanut protein.
There is no need for an advisory warning label for peanut

because the only probable risk of peanut exposure is highly
refined peanut oil with little or no protein present.
47
Example 2.
Production of two similar condiment sauces on the

same line, one of which contains mustard oil
Step
Example
Horseradish sauce A does not contain any mustard ingredients.
A horseradish sauce containing mustard oil is produced on the

same line as horseradish sauce A.
Despite rigorous GMP, there is a probable risk of crosscontamination under normal operating conditions as the two
horseradish sauces are made using shared equipment.
2a
Mustard is not already declared in the ingredients list.
Mustard oil is exempt from allergen labelling when present as

an intentionally added ingredient.
Not applicable.
Not applicable.
There is no need for an advisory warning label for mustard

because the only probable risk of mustard exposure is an
ingredient/derivative already legally exempted from allergen
labelling even when intentionally present.
Example 3.
Production of tea cakes in the same bakery as burger

buns with sesame seeds
Step
Example
Tea cakes do not contain any sesame seeds.
Teacakes are made using the same tins and oven as burger buns
with sesame seeds.
operating conditions.
48
2a
Sesame is not already declared in the ingredients list.
Sesame seeds are not exempt from allergen labelling when

Sesame seeds are small particles, which will be unevenly

distributed and cross-contamination is difficult to manage.
Although teacake production is scheduled first followed by

sesame seed burger buns, followed by a thorough clean at the
end of the day, a visual inspection of teacake batches show
that teacakes sometimes contain sesame seeds.
There is a need for an advisory warning label for sesame because

GMP measures in place cannot control cross-contamination and
are insufficient to manage the identified risk.
Example 4.
Production of cheese flavoured potato crisps on same

line as salted potato crisps
Step
Example
Salted potato crisps do not contain any cheese.
Salted potato crisps are made on the same line as cheese

flavoured crisps.
operating conditions.
2a
Cheese (milk) is not already declared in the ingredients list.
Cheese (milk) is not exempt from allergen labelling when

Cheese flavouring is a fine powder, which is evenly distributed.
Rigorous GMP measures are in place. Shared equipment is

accessible for cleaning. Physical segregation measures are in
place. Shared equipment is minimised. Salted potato crisp
production is scheduled first, followed by cheese flavoured
product. Salted potato crisp production can only re-start
following a thorough clean, inspection and sign-off that
equipment meets visually and physically clean standard.
There is no need for an advisory warning label for cheese (milk)

because GMP measures in place are clearly managing crosscontamination and are sufficient to manage the identified risk.
49
Example 5.
Production of two pasta products on the same line,

only one of which contains egg
Step
Example
Pasta A does not contain any egg ingredient.
It is made on the same line as pasta B containing egg.
2a
Egg is not already declared in the ingredients list of pasta A.
Egg is not exempt from allergen labelling when present as an

intentionally added ingredient.
Egg is added to the pasta mix pre-extrusion as a powder which

is evenly distributed. Extruded pasta shapes can be lodged in
various locations post-extrusion.
Production of pasta B is scheduled after pasta A to minimise

carry-over of egg-containing material. Due to the nature of the
product, daily change-over wet cleaning throughout the
process is not possible except at the weekend shut down
when the line is able to dry out.
The line is rigorously visually inspected following daily
changeover dry cleaning routines to minimise any product
retention.
50
As no further measures can be taken to reduce a) egg residues

from the pre-extruded product flow, or b) probable risk of
particulate product cross-contamination, there is a need for
an advisory warning label for egg for pasta A.
Step 6.
Production of coleslaw in an area where Waldorf Salad

is also produced
Step
Example
The coleslaw recipe does not contain deliberately added

allergenic ingredients. The mayonnaise used is a stabilised
oil/water/vinegar emulsion.
A Waldorf salad containing walnuts and celery is produced in

the same premises. The Waldorf salad is produced on the
same line, at the end of the coleslaw production run, and it is
followed by a wet wash down to a visually and physically
clean standard. There is a probable risk of crosscontamination under normal operating conditions since the
two salads are made using shared equipment.
2a
Nuts and celery are not declared on ingredients list.
These ingredients are not exempted from labelling.
The potential cross-contaminating allergenic materials are

walnut and celery pieces, which will be unevenly distributed,
and therefore the cross-contamination maybe difficult to
manage. Moreover, the configuration of the plant may be such
that it will be impossible to thoroughly check all areas.
Walnuts:
Rigorous GMP procedures are in place, the shared equipment
is wet washed after every run to a visually and physically
clean standard, and physical segregation measures are in
place. Small pieces of nuts are very difficult to manage
throughout the plant and therefore it warrants additional
consideration for use of advisory labelling for nuts (walnuts).
Celery:
The cross-contamination by pieces of celery is easier to
manage. The wet wash is followed by an inspection and signoff that the equipment meets the visually and physically
clean standard.
Walnuts:
There is a need for an advisory label for nuts (walnuts) for the
coleslaw.
Celery:
There is no need for an advisory warning label for celery.
51
Appendix IV: Allergen Testing Methods

Testing methods play an important part in the validation and ongoing
verification of Allergen Management Plans and need careful
consideration. Local Authority Environmental Health Officers and
Trading Standards Officers can provide advice on appropriate testing
methods. The process of detection usually begins by obtaining a sample
of the food and, in the laboratory, preparing a test portion for extraction
and analysis. Sampling methods must be carefully considered, depending
on the particular allergen being tested for.
Foods used as liquids or fine powders (such as egg, milk, and cereal flours)
tend to be spread throughout food products but distribution can be very
uneven for peanuts, nuts and whole seeds. Food matrices, composition
(acidity, salinity), processing techniques, and length of storage all affect
the survival of allergens and the ability to detect trace levels.
Differences in kits must also be thoroughly investigated before choosing
the best method available and any limitations of the testing method
being used should be recognised. The amount of allergen detected by
the different test kits can be expressed in different ways and it is
important to understand exactly what is being measured. This could be
expressed as the amount of the specific allergenic protein, such as casein
in milk, or the equivalent amounts of total milk protein or whole milk.
Immunoassay-based laboratory kits, mostly using Enzyme Linked
ImmunoSorbent Assay (ELISA) techniques, are one of the most
commonly used techniques for detecting allergens. They are both
specific and sensitive and can be used for most food-related analytical
samples where appropriate.
DNA-based detection, based on Polymerase Chain Reaction (PCR)
techniques, is growing in popularity. It requires sophisticated laboratory
conditions and lacks the ability of ELISA to quantify allergen levels in
foods. Results need to be carefully interpreted to avoid false positives.
This is because of the absence of threshold levels, the fact that this
method detects DNA from the allergenic source food and not the
protein itself, and it is both highly sensitive and lacks quantification.
Swabbing techniques are currently only used in conjunction with
immunoassay kits, but may have the potential to be extended to DNA
detection. These can be particularly useful tools in the validation and
ongoing verification of allergen risk management plans, particularly
cleaning regimens.
52
In the manufacturing environment, where time and/or analytical

capabilities may be limited, raw materials, environmental swabs or final
products can be tested using rapid, simple immunoassays within a few
minutes to give simple visual readouts of the presence or absence of the
allergen. However, some of these tests are significantly less sensitive than
laboratory methods. Rapid tests are available for gluten and more
recently rapid tests for peanut have emerged.
Another rapid test that is available, measures the presence of ATPase. A
positive with this method is an indication only of the presence of protein
in general, rather than the presence of specific proteins from an
allergenic food. This test can be used for checking general cleaning
efficiency but a positive result cannot give information on which protein
is present.
Recent developments in the application of gluten testing have resulted in
new, more sensitive methodology, developed by Professor Enrique
Mndez, becoming available. This test, which has been temporarily
endorsed by the CODEX Committee on Methodology, Analysis and
Sampling (CCMAS) in April 2005, is scheduled for further discussion in
November 2006.
Important
It is important to recognise that the development of analytical methods
for detecting and quantifying levels of allergens in foods is still at an early
stage. Although a number of methods have been developed to date, the
EU has not yet agreed independently validated methods for all the
allergens for which statutory ingredients labelling is required, nor are
there recognised and readily available standard reference materials for
food allergens (with the exception of peanut). In addition, commercial
kits that are currently available may vary in sensitivity and specificity and
their effectiveness across a wide range of food materials may vary.
Therefore, food producers, for the time being, can adopt a visually and
physically clean standard for assessing the risk of possible allergen crosscontamination. This requires a thorough visual inspection of the
production line (following cleaning) and the final product.

Appendix VI: Glossary/Abbreviations

Allergen
A substance, usually a protein, capable of inducing an allergic reaction.
Anaphylaxis/Anaphylactic Shock
Acute form of allergy characterised by uticaria, swelling of the lips,
shortness of breath, and rapid fall in blood pressure. Without immediate
treatment which consists of intramuscular injection of adrenaline,
anaphylaxis can be fatal.
Antigen
Substance, often protein in nature, capable of inducing an immune
response, for example, a food allergen.
Arachis Oil
Peanut oil.
ATPase Test
A quick, simple test used to check the effectiveness of wet cleaning
procedures. ATPase is an enzyme involved in cell metabolism in plants,
animals and microbes and so, if it is detected, it shows that some organic
matter is present, although it cannot be used to distinguish whether the
ATPase comes from food residues or microbes.
Changeover
When a production line is being used to produce more than one end
product, the switch between products, which normally involves a
thorough cleaning procedure, is known as a changeover.
Coeliac Disease
A life-long autoimmune condition characterised by damage to the small
intestinal wall due to intolerance to gluten protein present in wheat, rye,
barley, oats, spelt, kamut or their hybridised strains.
Consumer Testing
This refers to product trials carried out in public places such as
supermarkets etc.
Co-products
Products which are removed from the normal production chain for
quality reasons, but which may still be sold for human consumption.
56
Cross-Contamination
The unintentional presence of another substance in the final product. In
the context of allergens, it usually refers to trace amounts of allergenic
foods which, whilst not of themselves unwholesome, may be
problematic for those suffering from particular allergies.
Derivative/Derived Ingredient
An ingredient produced from one of the 12 specified allergens in Annex
IIIa of Directive 2000/13/EC.
ELISA
Enzyme Linked ImmunoSorbent Assay: a sensitive technique for the
detection and measurement of compounds, including proteins such as
food allergens.
Equivalent Standard
The evidence to demonstrate little or no material of allergenic
significance. This would include considering test results and
processing/dilution factors.
Food Allergy
A reproducible adverse reaction to a food or food ingredient that
involves the immune system, for example, allergy to peanut, nut, fish,
shellfish, egg or milk.
Food Intolerance
A reproducible adverse reaction to a food or food ingredient that does
not involve the immune system for example, lactose.
Hazard Analysis
Practice by which a process is examined to identify potential hazards that
can arise and determine measures by which they can be managed.
HACCP
Hazard Analysis and Critical Control Points.
PCR
Polymerase Chain Reaction: a sensitive method used to amplify a specific
region of DNA (genetic material).
Processing Aid
An additive or material used in the production of a food, where there are
only unavoidable residues remaining in the final food and these residues
do not perform any technological function in the final food.
57
Reference Material
An established material with defined properties that can be used to
validate a measurement method and allow the calibration of results.
Refined Oil
Oil which has been highly processed and therefore contains only minute
quantities of protein (for example, highly refined peanut oil as opposed
to unrefined or cold-pressed oils).
Re-work
This is the material left over from production, which is often reused to
make the same or similar product.
Threshold
For the purposes of this document the term refers to the amount needed
to elicit an allergic reaction in a sensitive individual within a given
population.
Unintentional Presence
Refers to the accidental inclusion or contamination of a food by another
ingredient (in this context an allergen).
Visually and Physically Clean
This is an inspection standard which is usually applied following
appropriate cleaning where there is no visible presence or residue of
cross-contaminating allergenic material. For example:
1)
no visible particles of food on contact surfaces of shared

equipment.
2) no wheat grains in a consignment of maize.

Waste
Materials that no longer have any use and which must be removed and
kept separate without contacting anything within the food production
chain so as to avoid cross-contamination.
Work in Progress
Part processed or semi-finished product, which is not wrapped, and
therefore still at risk of cross-contamination with allergens when moved
around a food production area or between premises.
