What are Common Food Allergens in Canada?
Food allergens represent substances in food that can trigger adverse immune system reactions in sensitive individuals. In Canada, health authorities have identified a specific set of priority food allergens that pose significant risks to public health. Understanding food allergies requires recognizing which foods commonly cause allergic responses.
Defining Food Allergens
A food allergen is a protein within a food that can cause an abnormal immune system response when consumed. When someone with a food allergy encounters these proteins, their body mistakenly identifies them as harmful, triggering defensive mechanisms that can range from mild symptoms to potentially life-threatening reactions. Canadian regulations require clear labelling of these substances to protect vulnerable individuals.

Canada recognizes several key food allergens that account for the majority of allergic reactions. These priority allergens include:
-
Milk and dairy products
-
Eggs
-
Peanuts
-
Tree nuts (almonds, walnuts, cashews)
-
Fish
-
Shellfish
-
Soy
-
Wheat
-
Sesame seeds
-
Mustard
These foods represent approximately 90% of all documented food allergies in Canada.
To clarify the top food allergens recognized in Canada, the following table lists each priority allergen along with typical examples and brief notes on prevalence or risk.
