How to use the poster

Anything can be an allergen, including dust, medication, plants, animals, and food. In a kitchen, a set of common food allergens needs to be known and disclosed. Symptoms differ between people and can range from mild to severe. In rare cases a reaction can be life-threatening, known as anaphylaxis. The poster keeps the list and the warning signs in front of the team.

Every kitchen is different. This poster is a general guide, not a one-size-fits-all rule. The allergens in your dishes and the way you label and disclose them depend on your menu and your local health unit. Review it and adapt it to your facility before you rely on it. Probe It Food Safety provides this resource for general guidance only.

An allergen question is never a small one. The same dish that gives one guest a runny nose can close another guest's throat. When a customer asks what is in a dish, the answer is never a guess. If staff are not sure, they check, and if they cannot be sure, they say so. A poster on the wall keeps the list familiar, so nobody is trying to remember it under pressure.
