A chicken allergy is an adverse immune response after consuming chicken or its byproducts. Many chicken allergies are related to egg allergies. Some people who experience an allergic reaction to eggs will often experience the same symptoms when they eat chicken. This is known as bird-egg syndrome. Those with this syndrome are allergic to a substance found in egg yolk and to chicken serum albumin, also known as alpha-livetin. There have been a few cases of people who are allergic to chicken but not to eggs. In this case, the cause of the allergy is unknown. Chicken allergies can be minor or very severe and symptoms of a chicken allergy can occur up to several hours later.

A blood test measures the antibodies in your blood responsible for your allergic reaction to chicken.

During this time, refrain from eating chicken. An allergy elimination test requires you to remove chicken and its byproducts from your diet. Your allergist may also ask you to eliminate eggs, turkey, and squab (pigeon) since they are in the same chicken allergy food list. An accurate test lasts two to four weeks. If symptoms subside after eliminating the above foods from your diet, there’s a high chance that you are allergic to them. Chicken Allergy Treatment Antihistamines work well for treating symptoms related to chicken allergies. An allergy specialist can prescribe cortisone creams to help with hives and inflammation. Your doctor can also provide an inhaled corticosteroid for breathing problems if necessary. Any gastrointestinal symptoms will resolve on their own. For more severe allergies, ask your allergist about epinephrine injection. If you require an EpiPen, you will be given directions on how to administer it. It’s important to teach family members how to administer the injection as well. Chicken Allergy Frequently Asked Questions If I’m Allergic to Chicken, Can I Eat Other Birds?
