For families managing food allergies, understanding the most common allergens is key to keeping your child safe. In the United States, the FDA identifies nine major food allergens responsible for most allergic reactions. Knowing these allergens, recognizing hidden sources, and preventing cross-contact can help you make informed choices. Here’s a guide to the nine most common food allergens and tips for managing them safely.

Common in dairy products like butter, cheese, and yogurt. Hidden sources include processed meats, baked goods, and sauces.
2. Eggs
Found in baked goods, pasta, sauces, and some processed foods.
3. Peanuts
A leading cause of severe allergic reactions. Watch for hidden sources in baked goods, sauces, and certain ethnic cuisines.

Common Signs of Allergic Reactions
Allergic reactions can range from mild to severe, and symptoms may appear minutes to hours after exposure. Be aware of these common signs:
-
Hives or skin rash
-
Swelling of lips, face, or tongue
-
Difficulty breathing or wheezing
-
Stomach pain, nausea, or vomiting
-
Dizziness or fainting
Severe reactions (anaphylaxis) require immediate treatment with epinephrine. For a full breakdown of symptoms and how to recognize them, refer to FARE’s guide on identifying allergic reactions.
Avoiding Cross-Contact at Home
Cross-contact happens when allergens come into contact with otherwise safe foods. Here are steps to reduce the risk:
-
Use separate utensils: Keep separate cutting boards, knives, and cookware for allergen-free foods.
-
Label allergen-free zones: Dedicate specific shelves or sections of your kitchen for allergen-free items.
-
Clean thoroughly: Wash hands, surfaces, and utensils with soap and hot water after handling allergens.
Be Prepared: Emergency Plans and Epinephrine
Despite our best efforts, accidental exposures can happen. Being prepared can save a life:
-
Have an Emergency Care Plan: Work with your doctor to create a written plan that outlines how to recognize and treat allergic reactions. Keep copies with caregivers, schools, and family. Download FARE’s Food Allergy & Anaphylaxis Emergency Care Plan here.
-
Epi First, Epi Fast: Always carry two doses of epinephrine and use it at the first sign of a severe reaction. Delaying treatment can be dangerous.
-
Inform Others: Make sure friends, family, teachers, and caregivers know how to use an epinephrine auto-injector and what steps to take in case of an emergency.
