What is 14 Declarable Food Allergens?

UK food law requires businesses to declare 14 specific allergens whenever they are used as ingredients: celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, tree nuts, peanuts, sesame, soybeans and sulphur dioxide/sulphites. For prepacked and loose foods, allergen information must be available to customers, and on menus or labels. Failure to provide accurate allergen information is a criminal offence enforced by environmental health officers.
