These include milk, eggs, peanuts, tree nuts, soy, wheat, fish, shellfish and sesame.[1] Knowing them is the first step toward managing risk and staying safe.

Food allergies affect about 11% of U.S. adults – even if you are not directly affected, someone you know likely is.[2] Understanding food allergens helps reduce anxiety and allows people to make safer choices when buying, preparing or sharing food.[3]
