What does the term "cross-contamination" mean?

The term "cross-contamination" refers specifically to the transfer of harmful bacteria or pathogens from one food item to another. This can happen during food preparation when raw foods, especially meats, come into contact with ready-to-eat foods or when utensils and surfaces are not properly sanitized after being in contact with raw ingredients.

Understanding cross-contamination is critical in food safety practices, as it emphasizes the importance of keeping raw and cooked foods separate to prevent foodborne illnesses. For instance, using the same cutting board for raw chicken and then for vegetables without cleaning it can lead to the vegetables becoming contaminated with bacteria from the chicken. This is a fundamental concept in maintaining hygiene in food preparation areas.

Other options do not accurately represent the definition of cross-contamination. The cooking of food at different temperatures is related to food safety but does not define the term. A method of food storage does not pertain to the transfer of bacteria, and the combining of flavors in cooking refers to culinary techniques, which is unrelated to the safety issue surrounding contamination.
