Ontario Food Handler Certification Practice Exam

What might be a sign of cross-contamination?

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

2. Cooking food to the correct temperature

3. Storing food items in separate containers

4. Washing hands before handling food

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

Using the same cutting board for raw meat and vegetables is a clear indication of cross-contamination. Cross-contamination occurs when harmful bacteria or allergens are transferred from one food item to another, usually through direct contact or shared surfaces. In this scenario, if raw meat is cut on the same board used for vegetables without proper cleaning in between, bacteria from the meat can contaminate the vegetables, posing a significant risk for foodborne illnesses. The other choices highlight safe food handling practices: cooking food to the correct temperature ensures that harmful bacteria are killed, storing food items in separate containers prevents contact and potential contamination, and washing hands before handling food minimizes the risk of transferring pathogens. Each of these practices contributes to a safer food preparation environment, contrasting the risk associated with using the same cutting board for different food types.
