According to the US Food and Drug Administration (FDA), millions of Americans experience allergic reactions to food each year. Though mostly with mild and minor symptoms, some of these allergies may cause severe reactions and can be fatal.
The FDA has listed the following information for the public to better understand and handle food allergies.
What Are Major Food Allergens?
While more than 160 foods can cause allergic reactions in people with food allergies, the law identifies the eight most common allergenic foods. These foods account for 90 percent of food allergic reactions, and are the food sources from which many other ingredients are derived.
The eight foods identified by US law are:
1. Milk
2. Eggs
3. Fish (e.g., bass, flounder, cod)
4. Crustacean shellfish (e.g. crab, lobster, shrimp)
5. Tree nuts (e.g., almonds, walnuts, pecans)
6. Peanuts
7. Wheat
8. Soybeans
These eight foods, and any ingredient that contains protein derived from one or more of them, are designated as "major food allergens" by FALCPA.
How Major Food Allergens Are Listed
The law requires that food labels identify the food source names of all major food allergens used to make the food. This requirement is met if the common or usual name of an ingredient (e.g., buttermilk) that is a major food allergen already identifies that allergen's food source name (i.e., milk). Otherwise, the allergen's food source name must be declared at least once on the food label in one of two ways.
The name of the food source of a major food allergen must appear:
1. In parentheses following the name of the ingredient.
Examples: "lecithin (soy)," "flour (wheat)," and "whey (milk)"
- OR -
2. Immediately after or next to the list of ingredients in a "contains" statement.
Example: "Contains Wheat, Milk, and Soy
