Question

1. how should a food handler test the temperature of food?

check the temperature dial of the oven
look at the food and see if it appears done
use a clean and sanitized thermometer
feel the food with the back of a hand

Explanation:

Checking the oven dial only gives the oven's set - temperature, not the food's actual temperature. Visual inspection and touch are not accurate for determining food safety temperatures. A clean and sanitized thermometer is the proper tool to accurately measure the internal temperature of food to ensure it has reached a safe level for consumption.

Answer:

Use a clean and sanitized thermometer
