Food Manager Practice Exam

Which of the following is an example of cross-contamination?

1. Cooking food at the right temperature

2. Using the same cutting board for raw meat and vegetables

3. Storing food at appropriate temperatures

4. Washing hands before food preparation

The correct answer is: Using the same cutting board for raw meat and vegetables

Cross-contamination occurs when harmful bacteria or allergens are transferred from one surface or food item to another, leading to potential foodborne illness. The scenario described in the second choice is a clear example of this. When the same cutting board is used for both raw meat and vegetables without proper cleaning in between, any bacteria present on the meat can contaminate the vegetables. This could result in the vegetables carrying pathogens that can cause illness when consumed. The other choices illustrate safe food handling practices. Cooking food at the right temperature ensures that harmful pathogens are killed, thus preventing foodborne illness. Storing food at appropriate temperatures helps to keep it safe and slows the growth of bacteria. Washing hands before food preparation is a fundamental hygiene practice that helps to remove any contaminants from the hands, further reducing the risk of cross-contamination.
