What is cross-contamination?

1. The mixing of food flavors

2. The transfer of harmful bacteria from one food to another

3. Cooking food at incorrect temperatures

4. The use of the same utensils for different foods

The correct answer is: The transfer of harmful bacteria from one food to another

Cross-contamination refers specifically to the transfer of harmful bacteria or other pathogens from one food or surface to another, which can occur during food preparation and handling. This is particularly critical in food safety because it can lead to foodborne illnesses when bacteria from raw foods, such as meat or poultry, contaminate ready-to-eat foods. Understanding cross-contamination highlights the importance of maintaining proper food safety practices, such as using separate cutting boards for raw and cooked foods, properly washing hands and utensils, and ensuring that foods are stored correctly. This concept is crucial for preventing the spread of diseases and protecting public health in food service environments.
