Allergic reactions to sesame

An allergic reaction usually happens within minutes after being exposed to an allergen (e.g., sesame), but sometimes it can take place several hours after exposure. Anaphylaxis is the most serious type of allergic reaction.

Symptoms of anaphylaxis generally include two or more of the following body systems:

If you have a sesame allergy, keep an epinephrine auto-injector (e.g., EpiPen®, ALLERJECT®) with you at all times. Epinephrine is the first-line treatment for severe allergic reactions (anaphylaxis).


Be allergy-aware: How to avoid sesame

  • Read ingredient labels every time you buy or eat a product. If the label indicates that a product “Contains” or “may contain” sesame, do not eat it. If you do not recognize an ingredient, if there is no ingredient list available, or if you don’t understand the language written on the packaging, avoid the product.
  • Do the Triple Check and read the label:
    • Once at the store before buying it.
    • Once when you get home and put it away.
    • Again before you serve or eat the product.
  • Always carry your epinephrine auto-injector. It’s recommend that if you do not have your auto-injector with you, that you do not eat.
  • Check with manufacturers directly if you are not sure if a product is safe for you.
  • Be careful when buying products from abroad since labelling rules differ from country to country.
  • Watch for cross-contamination, which is when a small amount of a food allergen (e.g., sesame) gets into another food accidentally, or when it’s present in saliva, on a surface, or on an object. This small amount of an allergen could cause an allergic reaction.
  • Bakeries can be a source of sesame cross-contamination because sesame seeds are used in the kitchens as a topping on many breads and buns.
