Question 1
What is cross-contamination in a food service setting?
Answer: Cross-contamination is the transfer of harmful microorganisms or substances from one food, surface, or person to another, potentially causing foodborne illness.
Question 2
What is the difference between direct and indirect cross-contamination?
Answer: Direct cross-contamination occurs when a contaminated food touches another food. Indirect cross-contamination occurs when a contaminant is transferred through an intermediate object, such as a cutting board or unwashed hands.
Question 3
Which type of food is considered the highest risk for causing cross-contamination to ready-to-eat foods?
Answer: Raw meat, poultry, and seafood are the highest risk because they commonly harbor pathogens such as Salmonella, E. coli, and Campylobacter that can be transferred to ready-to-eat foods.
Question 4
What does 'ready-to-eat food' mean, and why is it especially vulnerable to cross-contamination?
Answer: Ready-to-eat food is food that will be consumed without any further cooking step to kill pathogens. It is especially vulnerable because any contaminant transferred to it will not be destroyed before the food is eaten.
Question 5
What are the three main routes through which cross-contamination can occur?
Answer: Cross-contamination can occur through food-to-food contact, equipment/surface-to-food contact (including utensils and cutting boards), and people-to-food contact (such as unwashed hands).
