In the United States, the Food and Drug Administration (FDA) has identified 9 foods that qualify as major allergensand created legislations to determine how they should be declared on labels for consumer awareness. Two laws – the Food Allergen Labeling and Consumer Protection Act (FALCPA) of 2004 and the Food Allergy Safety, Treatment, Education and Research (FASTER) Act of 2021 – established the nine allergens that food manufacturers must declare: milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame (which was the most recent addition as of January 1, 2023).
