Food allergen cross-contact barriers

This bowtie maps allergen cross-contact from ingredients in a kitchen to potential customer harm. The top event is an allergen reaching a meal intended to be allergen-free. Supplier and labelling failures are separated from preparation-equipment failures because the controls are different. The recovery side includes withdrawing the meal, helping the customer and tracing the event. A kitchen team can use the diagram to discuss which controls are active for a specific menu and who verifies them. Add the actual allergens, recipes, equipment and local reporting requirements before use. This example supports discussion only and does not replace food-safety plans, allergen declarations or emergency medical advice.

Show labels, shared equipment and incorrect handover as threats, with supplier checks, utensils, cleaning, order flags and final checks as barriers. Show allergic reaction, hospital treatment or recall and loss of confidence with withdrawal, first aid, escalation, traceability, communication and corrective-action barriers.”

שאלות נפוצות

שאלות נפוצות

What is allergen cross-contact?

It is the unintended transfer of an allergen into food that should not contain it.

Why put cleaning on the left?

Validated cleaning helps prevent shared equipment from contaminating a meal before service.

Can this cover packaged food?

Yes. Packaging and label-verification threats can be adapted for a production setting.
