Food allergens are the 14 substances listed in Annex II to Regulation (EU) 1169/2011. Their presence must be indicated to the consumer also for non-prepacked food (Article 44), and Regulation (EU) 2021/382 extended separation duties into Regulation 852/2004 to prevent their cross-contamination.

- The allergens subject to mandatory declaration are the 14 listed in Annex II to Regulation (EU) 1169/2011 Annex II of Regulation (EU) No 1169/2011.
- Their presence is a mandatory particular, emphasised relative to other ingredients Article 9(1) of Regulation (EU) No 1169/2011 Article 21(1) of Regulation (EU) No 1169/2011.
- The information is also due for non-prepacked food, in the manner set by Member States Article 44(1) of Regulation (EU) No 1169/2011.
- Since 2021, Regulation (EU) 2021/382 requires that equipment used for allergenic foods not be used for products not containing them without cleaning, already at primary production Annex I, Part A, point 5-bis of Regulation (EC) No 852/2004.

Commentary
The 14 allergens of Annex II
The list of allergens subject to mandatory declaration is exhaustive and is found in Annex II to Regulation (EU) 1169/2011 Annex II of Regulation (EU) No 1169/2011: cereals containing gluten, crustaceans, eggs, fish, peanuts, soybeans, milk, tree nuts, celery, mustard, sesame seeds, sulphur dioxide and sulphites (above 10 mg/kg or 10 mg/l), lupin and molluscs. They are fourteen categories, some with specifications (gluten-containing cereals and tree nuts include several species). The list may be updated by the Commission in the light of scientific knowledge.
The information regime is in the same regulation: any ingredient or processing aid causing allergies or intolerances used in the manufacture and still present in the finished product is a mandatory particular Article 9(1) of Regulation (EU) No 1169/2011. In the list of ingredients such substances are emphasised through a typeset that clearly distinguishes them from the other ingredients, for example by means of the font, style or background colour Article 21(1) of Regulation (EU) No 1169/2011.
Allergens in non-prepacked food
The point most often misunderstood concerns non-prepacked food — catering, deli counters, loose products. For these too, allergen information is mandatory: where food is offered for sale to the final consumer or to mass caterers without prepackaging, allergen information is provided in the manner Member States may lay down Article 44(1) of Regulation (EU) No 1169/2011. The form (menu, notice, consultable register, verbal information supported by documentation) is left to the national legislator, but the informational content is due everywhere. For a restaurant or a café this means the absence of a label does not exempt from communicating the presence of allergens.
Preventing spread: the 2021/382 changes
Downstream information is not enough: the allergen must be kept from ending up where it should not. Regulation (EU) 2021/382, in force from 24 March 2021, inserted specific duties into Regulation (EC) 852/2004 Article 1 of Regulation (EU) 2021/382. In primary production, equipment, conveyances and containers used to harvest, transport or store allergenic substances of Annex II to Regulation 1169/2011 must not be used for food not containing them, unless cleaned and checked for the absence of visible debris Annex I, Part A, point 5-bis of Regulation (EC) No 852/2004. A mirror rule applies to later stages: equipment, conveyances and containers used to process, handle, transport or store allergenic products must not be used for food not containing them without cleaning and a check for the absence of visible debris Annex II, Chapter IX, point 9 of Regulation (EC) No 852/2004. It is the regulatory bridge between allergen management and cross-contamination.
Allergens and HACCP
Allergen management is a chemical hazard to be addressed in the hazard analysis of the HACCP system Article 5(2) of Regulation (EC) No 852/2004. In many businesses control is achieved through prerequisites — dedicated cleaning, separation, production procedures — rather than a CCP. The Codex Alimentarius has devoted a specific code of practice to the topic, CXC 80-2020, on food allergen management for operators. The traceability of allergenic ingredients along the chain is the premise for correctly managing labelling and recalls.
Common errors
- Assuming non-prepacked food is exempt from allergen information. The duty applies to non-prepacked food too, in the manner set by Member States Article 44(1) of Regulation (EU) No 1169/2011: in catering, the presence of allergens must still be communicated.
- Treating "gluten-free" or "traces of" as free-form wording. Annex II allergens must be declared and emphasised in the ingredient list Article 21(1) of Regulation (EU) No 1169/2011; voluntary absence claims are subject to their own rules and do not replace the declaration duty.
- Ignoring equipment separation. Since 2021 Regulation 852/2004 prohibits using for allergen-free food the equipment used for allergenic products without cleaning and checking Annex II, Chapter IX, point 9 of Regulation (EC) No 852/2004: a label alone does not cover cross-contamination.
Frequently asked questions
How many allergens must be declared?
Fourteen, listed exhaustively in Annex II to Regulation (EU) 1169/2011 Annex II of Regulation (EU) No 1169/2011: from gluten-containing cereals to molluscs, including milk, eggs, fish, crustaceans, peanuts, soy, tree nuts, celery, mustard, sesame, sulphites and lupin.
Must allergens be indicated at a restaurant?
Yes. For non-prepacked food, allergen information is mandatory, in the manner set by Member States Article 44(1) of Regulation (EU) No 1169/2011. A restaurant must be able to communicate the presence of allergens in dishes, for example via menus, notices or a consultable register.
How must allergens be emphasised on the label?
In the list of ingredients, through a typeset that clearly distinguishes them from the others — a different font, style or background colour Article 21(1) of Regulation (EU) No 1169/2011 — because they are a mandatory particular Article 9(1) of Regulation (EU) No 1169/2011.
What did Regulation 2021/382 change on allergens?
It inserted into Regulation (EC) 852/2004 the duty not to use for allergen-free food the equipment, conveyances and containers used for allergenic products without prior cleaning and a check for the absence of visible debris, both in primary production Annex I, Part A, point 5-bis of Regulation (EC) No 852/2004 and in handling Annex II, Chapter IX, point 9 of Regulation (EC) No 852/2004.
Are allergens a CCP in HACCP?
Not necessarily. An allergen is a chemical hazard to be assessed in the HACCP hazard analysis Article 5(2) of Regulation (EC) No 852/2004; it is often controlled through prerequisites (cleaning, separation, recipe management) rather than a critical control point.
Is 'may contain traces' wording mandatory?
No. Precautionary information on possible unintended presence is not imposed by Regulation 1169/2011, which governs the declaration of allergens actually used as ingredients Article 9(1) of Regulation (EU) No 1169/2011. Real prevention of unintended presence runs through the control of cross-contamination.
