What is cross-contamination?

• A. Mixing different food flavors
• B. Transferring harmful microorganisms from one food or surface to another
• C. Cooking different types of food together
• D. Using the same cooking oil multiple times

Answer: (B)

Cross-contamination refers to the process where harmful microorganisms, such as bacteria or viruses, are transferred from one food or surface to another. This can occur in a variety of ways, such as using the same cutting board for raw meat and vegetables without proper cleaning in between, or using utensils that have come into contact with contaminated food. The significance of understanding cross-contamination lies in its role in food safety; preventing it is crucial in reducing the risk of foodborne illnesses.

In this context, mixing different food flavors, cooking different types of food together, or using the same cooking oil multiple times do not address the transfer of harmful microorganisms between surfaces or foods. Thus, they do not accurately define cross-contamination.
