The 14 allergens

Allergen information: what food businesses must do

Every food business must be able to tell customers which of the 14 regulated allergens are in the food it sells. That depends on accurate ingredient information, careful handling in the kitchen and staff who know how to answer questions.

The useful questionIf a customer asks today, can anyone on shift give the right answer?
Know what is in it

Keep ingredient and recipe information accurate and current.

Tell customers

In writing, or verbally with a clear sign saying how to ask.

Prevent cross-contact

Separate storage, clean equipment and trained staff.

The 14 allergens you must declare

  • Celery
  • Cereals containing gluten (such as wheat, rye, barley and oats)
  • Crustaceans (such as prawns, crabs and lobsters)
  • Eggs
  • Fish
  • Lupin
  • Milk
  • Molluscs (such as mussels and oysters)
  • Mustard
  • Peanuts
  • Sesame
  • Soybeans
  • Sulphur dioxide and sulphites (above ten parts per million)
  • Tree nuts (such as almonds, hazelnuts, walnuts, brazil nuts, cashews, pecans, pistachios and macadamia nuts)

Food that is not prepacked

For meals and food sold loose, such as in a restaurant, café or takeaway, you must provide allergen information for every item that contains any of the 14 allergens. The guidance allows two ways to do this:

  • In writing: full allergen information on a menu, chalkboard or in an information pack.
  • Verbally: with a written notice in a clearly visible place explaining how customers can get the information.

The official guidance says written allergen information, supported by a conversation, works best for customers. Whichever method you use, the information must be accurate and consistent every time. Orders placed online or by phone need the same care.

Prepacked for direct sale (PPDS)

Food packed on the same premises before a customer orders it, such as sandwiches made and wrapped in the morning, is prepacked for direct sale. PPDS food needs a label with the name of the food and a full ingredients list, with the allergenic ingredients emphasised (for example in bold).

Keep the information reliable

Allergen answers are only as good as the information behind them. The guidance recommends that ingredient information is:

  • recorded on product specification sheets from suppliers;
  • kept on ingredient labels, with ingredients stored in their original or labelled containers;
  • included in recipes or explanations of each dish;
  • kept up to date whenever a recipe, supplier or product changes.

Many businesses keep an allergen matrix: a chart showing which dishes contain which allergens. The Food Standards Agency publishes a free template.

Where the app fits.

Food Hygiene Record Book does not build an allergen matrix. Keep your matrix and recipes as your business decides. The app keeps the daily records around them: delivery checks, the daily diary where changes and problems are noted, and the staff training register.

Handling allergens in the kitchen

  • Store ingredients and prepared foods separately, in closed and labelled containers.
  • Clean utensils and equipment before each use, especially after preparing food containing allergens.
  • Make sure staff receive training on allergens, including what to do when a customer asks.
  • If you cannot be sure a dish is free from an allergen, do not say it is. Tell the customer honestly.

Questions

Allergen questions

How many allergens must be declared in the UK?

Fourteen: celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, peanuts, sesame, soybeans, sulphur dioxide and sulphites, and tree nuts.

Can I tell customers about allergens verbally?

Yes, for food that is not prepacked, as long as a clearly visible written notice explains how customers can get the information. The official guidance says written information supported by a conversation works best.

What does PPDS mean?

Prepacked for direct sale: food packed on the premises before it is ordered, such as pre-wrapped sandwiches. It needs a label with the food's name and a full ingredients list with allergens emphasised.

Does Food Hygiene Record Book manage allergens?

No. The app does not create an allergen matrix or labels. It keeps the daily food-safety records around them, such as delivery checks, the daily diary and the staff training register.
