In the United States, nine foods account for 90% of food allergies: milk, eggs, peanuts, tree nuts, wheat, soy, fish crustacean shellfish, and sesame. Federal regulations require that food products containing any of these nine ingredients (or their allergenic proteins) must declare on the package or label which allergens are present using common names. Under the FASTER Act of 2021, sesame is recognized as the 9th major food allergen effective January 1, 2023. A sesame allergen fact sheet and poster is available from FDA on their website here.
