Tree Nuts

Quick Facts

  • Tree nuts are considered a priority allergen by Health Canada.
  • People with an allergy to one type of nut have a greater chance of being allergic to others.
  • People who are allergic to some tree nuts generally avoid all tree nuts and peanuts because of the risk of cross-contamination.

    • 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.
  • For tips on eating out, visit our guide for dining out with food allergies.
