Question

which action can help minimize food safety risks?
cleaning under the fingernails when washing hands
washing hands with water only before cutting an apple
using a grater to chop vegetables while preparing a meal
using the same cutting board to cut meat, green peppers, and onions

Explanation:

Cleaning under fingernails removes dirt and bacteria that could contaminate food. Using the same cutting board for different foods (meat, veggies) can cross - contaminate. Using a grater doesn't directly address food safety (more about prep). Washing hands with water only is insufficient (needs soap).

Answer:

cleaning under the fingernails when washing hands
