Which practice best prevents cross-contamination in a retail kitchen?

• A. Use separate equipment for raw and ready-to-eat foods.
• B. Store raw poultry above ready-to-eat foods.
• C. Wash hands only once per shift.
• D. Reuse same cutting boards for all foods without sanitizing.

Answer: (A)

Preventing cross-contamination comes down to physically separating the routes that bacteria can take from raw ingredients to ready-to-eat foods. Using separate equipment for raw and ready-to-eat foods creates a barrier: tools used on raw products aren’t used on foods that won’t be cooked, so any potential bacteria stay with the raw item and don’t transfer to edible items. This is especially important in a retail kitchen where ready-to-eat foods are often served or sold without further cooking.

Storing raw poultry above ready-to-eat foods invites contamination through drips and splash, making separation insufficient if not paired with proper storage practices. Washing hands only once per shift ignores the frequent transfers that happen after handling raw products, so pathogens can persist and move to other surfaces. Reusing the same cutting boards for all foods without sanitizing reintroduces bacteria to every item touched, defeating any cleaning steps.

So, dedicated equipment for raw versus ready-to-eat foods directly minimizes the risk of cross-contamination at the source, which is why it’s the best practice.
