Basics: Food Allergens in the US

Update: Joe Biden signed a law on April 23, 2021 that makes sesame the ninth major food allergen

Each year, millions of people around the world have allergic reactions, caused by wrong labelled food. As a result, food labels help allergic consumers identifying these foods and ingredients.

Most common food allergens

The following foods or ingredients cause 90 percent of allergenic reactions, according to the FDA.

  1. Milk
  2. Eggs
  3. Fish (e.g. flounder, bass, cod)
  4. Crustacean shellfish (e.g. crab, lobster, shrimp)
  5. Tree nuts (e.g. almonds, walnuts, pecans)
  6. Peanuts
  7. Wheat
  8. Soybeans
  9. NEW: Sesame

Food labels must identify all sources of food allergens that were used to produce the food. The allergen has to be declared at least once on the label of the food. Here are two options for the declaration of allergens:

  1. “Contains” statement: e.g. “Contains milk, wheat and soy”
  2. In parentheses: e.g. lecithin (soy), flour (wheat), whey (milk)

Cross-Contamination

In the context of food allergens, cross-contamination occurs when a residue or a trace of an allergenic ingredient becomes incorporated into another food, not intended to contain it. In the U.S., the FDA guidance says that statements like “may contain [allergen]” should not be used as a substitute for adhering the Good Manufacturing Practices (GMP) or be misleading.

Lab Services

In addition, allergen testing is performed in the Tentamus Group laboratories using ELISA and PCR tests. These tests allow the determination of the presence of a specific animal or plant DNA strand in a food. PCR is often used as an adjunct to ELISA testing because it is very sensitive in picking up trace amounts of celery and fish.
