The Food and Drug Administration is now requiring food labels to clearly state if a product contains any ingredients that contain protein derived from the eight major allergenic foods—milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, or soybeans. The agency estimates that about 2% of adults and 5% of infants and young children in the United States have food allergies and approximately 150 individuals die each year in the United States because of allergic reactions to food.
