This type of allergy is extremely rare, affecting roughly 0.6% to 5% of people. Typically, young adults and adolescents are most affected by chicken allergies.
This article discusses the symptoms, risk factors, and treatment options for people who suffer from this very rare food allergy.
Symptoms
The typical symptoms that occur when a person who is allergic to chicken include:
Swelling of the mouth, lips, tongue, face, and throat Shortness of breath Gastrointestinal distress Hives (urticaria)
Complications
Although rare, some serious symptoms can occur and affect the heart. These symptoms can include:
Shock Low blood pressure An irregular heartbeat Problems with how the ventricles function (hollow parts of the heart) A sudden stoppage of the heart, also known as cardiac arrest
These are symptoms of anaphylaxis, which is a severe and potentially life-threatening allergic reaction. Fortunately, this complication is rare.
Risk Factors
The factors most associated with an increased risk of developing a food allergy include:
Light-headedness Feeling as though you may faint Difficulty breathing Wheezing An increased heartbeat Skin that becomes clammy Confusion or anxiety Loss of consciousness
Hygiene Lack of exposure at an early age The composition of gut bacteria (microorganisms living naturally within the intestines) A person’s overall diet Obesity Vitamin D levels Having eczema
When it comes to a chicken allergy specifically, a person who is allergic to another type of poultry may be at an increased risk of developing an allergy to chicken as well.
Other poultry foods include:

In some cases, those who are allergic to other types of meat, including fish and pork, could also be at an increased risk.
Diagnosis
The diagnostic process for a chicken allergy is similar to diagnosing other food allergies. The process begins following the onset of symptoms.
People who have bird-egg syndrome are at an increased risk of developing an allergy to chicken. However, they don’t always develop one.
When a person eats chicken and notices that they experience the same symptoms every time, they should meet with an allergist, who specializes in allergies and allergy testing.
Tests used to diagnose a chicken allergy include:
Blood test: An allergy blood test checks for chicken-specific antibodies that are being created to fight off the allergen when the immune system responds to its presence. Skin prick test: A skin test involves the use of a small tool that resembles a comb. The allergen in question will then be placed on the combed or pricked area to see if there is a skin reaction. Elimination diet: In some cases, a healthcare provider will request that you refrain from consuming chicken for a period of time and then reintroduce it into your diet to see if symptoms return.
Treatment
The best way to treat a chicken allergy is to avoid eating chicken. This will keep the allergen out of your system so you won’t suffer from an allergic reaction.
Unfortunately, this process is easier said than done, because some foods may have chicken ingredients, such as soups, that you are unaware of unless you read the packaging.
For severe cases of chicken allergy, injectable epinephrine may be used. Epinephrine helps to treat life-threatening allergic reactions. People with this type of severe allergy to chicken will need to carry around an EpiPpen (which contains epinephrine) with them wherever they go in case they come into contact with chicken by accident.
Depending on the severity of your allergy, you may be able to take oral antihistamines to combat the allergic reaction if you happen to accidentally consume chicken and are having a mild reaction.
What to Avoid
If you have a chicken allergy, you should avoid any products that contain chicken.
Common foods that contain chicken ingredients include:
Chicken broths and soupsSome pet foods that contain chicken ingredients and could irritate your skin if touchedAny frozen meat products that may contain chicken
Food Alternatives
There are many other types of meat or food products that a person with a chicken allergy can substitute to avoid an allergic reaction. Examples of food alternatives include:
Tofu (food made from curdling soy milk)Jackfruit (an ancient variety of fruit)Tempeh (plant-based product made from soybeans)Seitan (wheat-based product that acquires the look and texture of meat when cooked)Cauliflower (a cruciferous vegetable)Plant-based chicken products (be sure to check the labels to ensure that there are no allergy-inducing ingredients)
Aside from the plant-based chicken, these products typically have little to no flavor and can therefore be used as a substitute for chicken by using the same spices or sauces as you would if you were making a chicken-based meal.
When to See a Healthcare Provider
If you experience allergy symptoms every time you consume chicken, it may be time to see your healthcare provider.
A provider will put you in touch with an allergist or suggest that you try an elimination diet to determine whether the chicken is what’s causing your symptoms.
Summary
A chicken allergy is a rare type of allergy that tends to affect young adults and adolescents. It occurs when the body’s immune system mistakes chicken as a dangerous substance and reacts to it, causing symptoms. Although a chicken allergy is typically mild, it can be severe in some cases.
The risk factors associated with chicken allergy include having other food allergies, eczema, or developing bird-egg syndrome later on in life. If you think you may have an allergy to chicken or poultry, you can speak with your healthcare provider about getting the proper tests done to confirm it and develop a treatment plan.
A Word From Verywell
Chicken is considered a staple ingredient in many kitchens, so avoiding it can be difficult for people with a chicken allergy. Fortunately, there are substitutes that work just as well in many chicken dishes that won’t result in side effects or symptoms. The adjustment period to living without chicken may be difficult, but it’s worth it if it means relieving yourself from unwanted allergy symptoms.
