What temperature must previously reheated foods and leftovers be heated to?

Previously reheated foods and leftovers must be heated to an internal temperature of at least 165°F (74°C) to ensure the destruction of harmful bacteria and to reduce the risk of foodborne illness. This temperature can be achieved by reheating the food in the oven, microwave, or on the stovetop until a food thermometer inserted into the thickest part of the food reads 165°F (74°C) or higher.
