Foodborne IllnessCâu 23 / 240
A prep cook cuts raw chicken and then, without cleaning, uses the same board and knife to slice tomatoes for a salad. What is this an example of, and why is it dangerous?
a.Cross-contamination — pathogens from raw poultry transfer to a ready-to-eat food that will not be cooked
b.Cross-connection — a plumbing hazard
c.Time-temperature abuse only
d.An allergen concern only, not a pathogen risk
Giải thích
This is cross-contamination: pathogens such as Salmonella and Campylobacter from raw chicken transfer via the board and knife to tomatoes that will be eaten without cooking. Preventing it requires separate or cleaned-and-sanitized equipment, color-coded boards, and proper sequencing. Because the salad is not cooked, there is no later kill step to destroy the pathogens.
