Describe a method to prevent cross contamination.

• A. Use separate chopping boards for raw meats and ready-to-eat foods
• B. Store raw meat above ready-to-eat foods
• C. Thaw foods at room temperature
• D. Leave knife used for raw meat on the counter

Answer: (A)

Preventing cross contamination comes down to creating a physical barrier between raw animal products and foods that are ready to eat. Using separate chopping boards for raw meats and ready-to-eat foods does exactly that: it stops bacteria on raw meat from being transferred to foods that won’t be cooked before eating. Juices, utensils, and hands can transfer pathogens, and keeping these foods on separate boards reduces the chance of any transfer happening. In practice, you can reinforce this with color‑coded boards or dedicated equipment, and always clean and sanitize boards after use to prevent any remaining bacteria from moving around. This approach is much safer than mixing surfaces, which is a common route for spreading contamination. The other practices undermine safety. Storing raw meat above ready-to-eat foods can let drips contaminate those foods. Thawing foods at room temperature promotes bacterial growth. Leaving a knife used for raw meat on the counter can spread contamination to hands, surfaces, and other foods.
