Final answer:
A food worker should wear gloves when working with food to protect it from contamination.
Step-by-step explanation:
A food worker should wear gloves when working with food to protect it from contamination. Nail polish and artificial nails can harbor bacteria and can easily chip off, contaminating the food. By wearing gloves, the worker creates a barrier between their nails and the food, reducing the risk of contamination.
