What is the minimum reheating temperature for foods, except commercially processed food in an intact package?

The minimum reheating temperature for foods, excluding commercially processed food in intact packages, is established at 165°F. This temperature is critical because it ensures that any potentially harmful pathogens present in previously cooked or prepared foods are effectively killed, making the food safe for consumption.

Reaching 165°F during reheating guarantees that the food reaches a temperature high enough to eliminate bacteria such as Salmonella, Listeria, and E. coli, which thrive in improperly stored and reheated foods. By adhering to this guideline, food safety standards are met, thereby reducing the risk of foodborne illnesses.

The other temperature options, while relevant in certain contexts, do not provide the same level of safety as 165°F for reheating foods. For instance, 135°F is often related to hot holding temperatures rather than reheating, and lower temperatures may not adequately address food safety concerns associated with pathogens that can survive improper heating.
