The legal list

The 14 allergens UK food businesses must declare

Fixed by Annex II of the food information regulation, the same in England, Scotland, Wales and Northern Ireland. The FSA lists them alphabetically, as below; each links to where it hides in a kitchen.

What is not on the list

Only the 14 must be declared. Garlic, onion, tomato, peas, chilli, kiwi and most fruit are not allergens in law, and neither are some foods people think of as nuts:

A customer may still ask about them. The honest answer comes from your recipe; what the law requires you to hold and give is the 14.

Two pairs people mix up

  • Crustaceans and molluscs are separate allergens. Prawns, crab and lobster are crustaceans; mussels, squid, scallops and the oysters in oyster sauce are molluscs.
  • Peanuts and tree nuts are separate too, and so is lupin, another legume found in some gluten-free flours.

Thresholds and exemptions

Only one allergen has a threshold: sulphur dioxide and sulphites, declared above 10 mg/kg or 10 mg/litre. A few highly processed derivatives are exempt, such as fully refined soybean oil, wheat-based glucose syrups and the cereals used to make spirits; each allergen page lists its exemptions.

Questions about the 14 allergens

Why are there 14 allergens in the UK?

The list comes from Annex II of Regulation (EU) No 1169/2011 on food information to consumers, kept in UK law after Brexit. It names the foods and ingredients responsible for most serious allergic reactions in Europe. Only these 14 have to be declared as allergens.

Is garlic, tomato or coconut one of the 14 allergens?

No. Garlic, tomato, coconut, pine nuts, chestnuts, peas, kiwi and chilli are not on the list. People can be allergic to them, and you can tell them what a dish contains, but you are not required to declare them as allergens.

What are the “15 allergens”?

There is no fifteenth allergen in UK law. Lists of “15” found online come from other countries' rules or split a group such as tree nuts in two. For a UK business, the legal list is the 14 on this page.

Do I need to name the specific nut or cereal?

On a label, yes: the law names the cereals (wheat, rye, barley, oats) and the eight tree nuts, and the FSA's guidance is to name them rather than write “gluten” or “nuts”. On a matrix, one column per allergen is the usual layout; you can add the detail in the dish name or a note.
