Sulphites: Allergen Awareness and Labeling Guidelines

Sulphites are used as a food additive and can occur naturally in some foods. They can cause allergic-like symptoms in some individuals and are considered a priority allergen by Health Canada. It's important to read ingredient labels when buying or consuming products and follow the Triple Check rule for severe reactions to sulphites. Labelling requirements for sulphites in Canada are in place, but exceptions exist.

Sulphites can go by various names, and they are found in a wide range of foods and non-food products, including alcoholic beverages, baked goods, condiments, deli meats, and more. They are also used in non-food items like home brewing sanitizing solutions and certain medications. Be cautious when purchasing items from outside Canada, as labelling rules may differ.
