Final answer:
Plastic gloves should be worn when handling raw or ready-to-eat food to prevent contamination. Proper handwashing is crucial before and after using gloves to ensure food safety.
Step-by-step explanation:
Plastic gloves must be worn when handling raw or ready-to-eat food to prevent contamination and spread of pathogens. They create a sanitary barrier between the hands and the food, thus reducing the risk of transmitting foodborne illnesses. Gloves should not replace proper handwashing, which is critical before and after glove use, and especially after handling food, using the bathroom, and when in contact with sick individuals. Proper handwashing techniques and personal hygiene are essential in maintaining food safety and overall health.
