Final answer:
Food must be reheated to a temperature of 165°F (74°C) to ensure it is safe to eat, as this is effective in killing potential bacteria.
Step-by-step explanation:
When reheating food, it should be heated to a minimum internal temperature of 165°F (74°C). This temperature is considered safe because it helps kill any bacteria that may cause foodborne illnesses. It's important to use a food thermometer to ensure that the food has reached the appropriate temperature before eating.
The temperature food must reach when being reheated to ensure safety is 165°F (74°C). This temperature is the standard for killing potential bacteria and ensuring food is safe for consumption. While not one of the answer options provided, the important takeaway is that higher temperatures beyond simple warmth are required to guarantee safety. Temperatures within the range of 40°F (4°C) to 140°F (60°C) can allow for rapid bacterial growth, so it is critical to surpass this range when reheating food. Using a meat thermometer can help ensure that the food reaches the appropriate and safe internal temperature when reheating.
