If you have a food allergy or intolerance, it’s critical for you to take the necessary precautions. However, whether you’re eating out or purchasing ready-made food, food businesses are legally required to label the main 14 allergens.

While people can be allergic to almost anything, some allergies are more prevalent than others. Established by the Food Standards Agency, the 14 allergens need to be mentioned (either on a label or on a menu) when used as an ingredient in food.

In this article, we cover the main 14 allergens, including what they are and where they are most commonly found.

What are the Main 14 Allergens?

  1. Celery
  2. Cereals containing gluten
  3. Crustaceans

  7. Milk
  8. Molluscs
  9. Mustard
  10. Nuts
  11. Peanuts
  12. Sesame Seeds
  13. Soya
  14. Sulphur dioxide (sometimes known as sulphites)

1. Celery

Celery isn’t the first allergen, you’d guess. It includes the celery stalks, leaves, seeds, and the root (celeriac). Common in both raw and cooked forms, celery can be found in a variety of foods, including:

  • Soups and stews
  • Salads
  • Vegetable juices
  • Stock cubes

  • Breads and pastries
  • Pasta and noodles
  • Breakfast cereals
  • Cakes and biscuits
  • Beer and malt beverages

3. Crustaceans

Seafood allergies are also extremely common. Crustaceans refers to hard-shelled sea creatures like crabs or lobster. Often found in seafood dishes, crustaceans are also a mainstay of Thai and South-Asian cuisines:

  • Shrimp, prawns, lobster, crayfish
  • Seafood dishes (like paella, gumbo)

  • Fish-based broths and soups

6. Lupin

Lupin is a type of legume used in gluten-free and healthy foods. Usually ground into flour, it’s a common replacement for wheat-based flour. Related to peanuts, cross-sensitivity means individuals allergic to one are most likely to be allergic to the other. Lupin can be found in:

  • Lupin flour and seeds
  • Gluten-free baked products
  • Certain types of pasta
  • Vegan meat alternatives
  • Specialty bread products

7. Milk

Dairy allergies are among the most common of the 14 allergens. Milk and its derivatives can be found in numerous foods:

  • Certain meat products (like sausages and deli meats)

10. NutsList Of The Main 14 Allergens

  • Nut butters (like almonds and cashews)
  • Baked goods and desserts
  • Cereals and granola
  • Nut oils

11. Peanuts

Peanuts are a legume that grows underground – sometimes, they’re referred to as groundnuts. Similar to nuts but with distinct allergenic properties, peanuts are found in:

  • Peanut butter and spreads
  • Snack foods (like trail mix and granola bars)
  • Asian cuisine (like Thai and Chinese dishes)
  • Baked goods and confectionery
