  • Egg allergy is one of the most common food allergies worldwide. It is usually outgrown by 10 years of age, but can persist in some individuals.
  • Egg allergy most commonly appears during the first year of life (the average is 10 months) and occurs during the first known exposure to egg. The reaction can present within minutes of exposure, and up to 2 hours post-exposure.
  • Common symptoms include hives, vomiting, and swelling. Though less common, anaphylaxis and respiratory/cardiovascular symptoms (e.g. coughing, wheezing, hypotension, throat tightening) can occur.
  • Those with egg allergies exist on a spectrum, with some individuals being allergic to all forms of egg (e.g. raw, cooked baked) and others only being allergic to raw or partially cooked egg products. This is because the baking process can reduce the allergenicity of the egg protein.
  • Children with an egg allergy are at an increased risk for a co-existing peanut allergy.
    Egg allergies are typically cross-reactive, meaning those who are allergic to hen’s eggs are also allergic to quail eggs, duck eggs, turkey eggs, etc.
