What does cross-contamination mean in a food service context?

• A. Cross-contact between non-food items
• B. The process of cleaning a surface
• C. The transfer of pathogens or contaminants from one surface or food to another, especially to ready-to-eat foods
• D. The storage of contaminated foods

Answer: (C)

Cross-contamination in a food service setting means the transfer of pathogens or contaminants from one surface or food to another, especially to ready-to-eat foods. This happens when microbes from raw meat, poultry, seafood, or contaminated items move onto utensils, cutting boards, countertops, or hands, and then end up on foods that won’t be cooked before eating. Because ready-to-eat items aren’t going to be reheated, any transferred bacteria or other contaminants can cause illness. That’s why preventing cross-contamination is all about keeping raw and ready-to-eat foods separate, washing hands frequently, using clean utensils and surfaces, and sanitizing equipment between tasks.

Other options don’t fit the concept as precisely. One describes cross-contact with non-food items, which isn’t about the microbial transfer between foods. Cleaning a surface is the opposite of contamination. Storing contaminated foods addresses a risk, but it’s not the transfer process that defines cross-contamination.
