What temperature should leftovers be re-heated to?

The recommended temperature for reheating leftovers is 165 degrees Fahrenheit. This temperature is crucial to ensure that any potentially harmful bacteria that may have developed while the food was stored are effectively killed off. Reaching this temperature guarantees that the food is safe to consume and helps to ensure that it is heated evenly throughout.

It's important to note that while higher temperatures, like 175 degrees or 180 degrees, may also render food safe, they aren't necessary for safety and could potentially lead to overcooking or degradation of the food's quality. Meanwhile, reheating to temperatures like 150 degrees is insufficient, as it does not guarantee that harmful bacteria are eliminated, leaving the food unsafe to eat.
