Which statement best defines cross-contamination?

• A. The transfer of pathogens from one surface or food to another.
• B. The transfer of flavors between foods.
• C. The spoilage of food due to improper refrigeration.
• D. The cooking of food to the proper temperature.

Answer: (A)

Cross-contamination is the transfer of pathogens from one surface or food to another. This can happen through hands, utensils, plates, cutting boards, or anything that touches raw foods and then comes into contact with ready-to-eat items. The danger is that bacteria or viruses can move from a contaminated surface to something you’ll eat, potentially causing illness, especially if the receiving food isn’t cooked further.

That’s why the statement about transferring pathogens between surfaces or foods is the best fit. Other ideas describe flavor transfer, spoilage from improper refrigeration, or cooking foods to a safe temperature. While those are important food-safety topics, they aren’t what cross-contamination means.
