What are Egg Allergies? Eggs are one of the most common foods that cause allergic reactions in the US. The best way to treat an egg allergy is to avoid it in the first place. Individuals with allergic reactions to eggs must be very careful about what they eat, always checking food labels and ingredient lists meticulously. Since this can be a pain-staking process, our NYC allergy specialists have provided some lists below that can help you identify egg ingredients so that you know what products to avoid. Egg products that can cause an allergic reaction can be hidden in foods where you might not expect them. You should be wary of products that list generic ingredients (like “binder,” “coagulant,” or “emulsifier”) because these could be egg products in disguise. Even pretzels, bagels, and other baked goods can be sources of unexpected egg ingredients – some stores coat these products in egg white to give them a shiny appearance. Egg-allergic individuals should also avoid eating fried foods that could contain egg in the coating. All these hidden forms of egg can cause allergic reactions. If you have questions about what foods you can safely eat, the allergy doctors at our NYC allergy clinics can be helpful in educating you about potential allergic reactions. Even tiny amounts of egg can cause an allergic reaction, including anaphylaxis (a life-threatening condition). The most common reactions are the result of someone eating or drinking a food that contains eggs. However, reactions can also occur after non-oral exposure, including immunization with an egg-containing vaccine. We recommend consulting our asthma and allergy clinic to help you decide if an immunization is safe for you or your child. One piece of good news: Egg-allergic individuals are often able to eat chicken, and may be able to tolerate the eggs of other birds (duck eggs, for example). Consult your NY doctor for more information.
