Final answer:
The thermometer stem or probe should be placed in the thickest part of the food to get an accurate reading of the internal temperature.
Step-by-step explanation:
When checking food temperatures, the thermometer stem or probe should be placed in the thickest part of the food, away from bones and fat. This will give an accurate reading of the internal temperature of the food. After inserting the thermometer, wait a few seconds for the reading to stabilize, and then note the temperature.
