Final answer:
Using thermometers, covering pans, and stirring food are important practices when working with food. Raw meat should never be mixed with cooked foods.
Step-by-step explanation:
When working with food, it is important to use thermometers to ensure that it reaches a high enough temperature to kill bacteria. Covering pans helps to trap heat and distribute it evenly, resulting in thorough cooking. Stirring food often also helps to distribute heat and ensure even cooking. Additionally, it is important to never mix raw meat with cooked foods to avoid cross-contamination.
