Which practice best reduces the risk of cross-contact with allergens in a kitchen?

• A. Separate utensils and cleaning tools
• B. Use shared utensils for all foods
• C. Rely on labels only
• D. Avoid cleaning after handling allergens

Answer: (A)

Preventing allergen cross-contact relies on keeping tools separate. Using dedicated utensils and cleaning tools for foods with allergens stops the transfer of tiny amounts of an allergen from one food to another, which is a common way cross-contact occurs in a kitchen. In practice, you can color-code or assign specific utensils, cutting boards, and scrubbers to allergen-containing items, and store them apart from other tools. If you don’t have dedicated tools, be sure to thoroughly wash, sanitize, and designate tools between tasks to reduce the risk.

Relying on labels alone isn’t enough because labels don’t guarantee that equipment used elsewhere didn’t transfer allergens, and some facilities process multiple items on shared tools. Using shared utensils for all foods increases the risk of spreading allergens, not just handling them separately. Avoiding cleaning after handling allergens leaves residual allergen on surfaces and utensils, which can contaminate other foods.
