Which of the following should food handlers do to prevent contamination?

Food handlers play a crucial role in maintaining food safety, and personal hygiene is a significant part of their responsibility. To prevent contamination, it's essential for food handlers to maintain their hands and nails in a condition that minimizes the risk of transmitting harmful pathogens to food.

Not wearing false nails is important because they can harbor bacteria and are harder to clean effectively. Additionally, keeping nails short and clean minimizes the risk of bacteria hiding underneath longer nails. Nail polish can also chip and potentially contaminate food, so avoiding it helps maintain cleanliness.

By addressing all these factors—wearing natural nails, keeping them short and clean, and avoiding nail polish—food handlers significantly reduce the chances of contamination. Therefore, the option that encompasses all these practices accurately reflects the comprehensive approach required for safe food handling.
