Question

how can a food handler prevent people - to - food cross - contamination:
frequent handwashing
proper separation and storage of potentially hazardous/high - risk foods
availability of multiple clean utensils or frequent cleaning and sanitizing of the same utensil
none of the above

Explanation:

People-to-food cross - contamination occurs when pathogens from a food handler (e.g., on hands) are transferred to food. Frequent handwashing removes pathogens from hands, reducing the risk of transfer to food.
Proper separation and storage of potentially hazardous/high - risk foods (option 2) is more about preventing cross - contamination between different types of foods (e.g., raw meat and ready - to - eat foods), not people - to - food.
Availability of multiple clean utensils or frequent cleaning and sanitizing of the same utensil (option 3) is about preventing utensil - to - food cross - contamination, not people - to - food.

Answer:

A. Frequent handwashing
