Typical allergens and diets are SupKit's guide to the main ingredient, not a product's label.

  • Irish (EU) law names 14 allergens: gluten cereals, crustaceans, eggs, fish, peanuts, soybeans, milk, tree nuts, celery, mustard, sesame, sulphites, lupin and molluscs.3
  • On packaged food, allergens must stand out in the ingredient list, for example through font, style or background colour.4
  • For unpackaged food, allergen information must be in writing and easy to find before you buy.3
  • 'May contain' warnings are optional, used only where cross-contamination can't be ruled out, and can't replace good manufacturing practice.4

Young children

  • Don't give whole nuts to children under five; crush or grind nuts, and spread nut butter thinly.5
  • Don't give honey to babies under 12 months, and don't add salt to a baby's food.6
