How long are leftovers safe in the refrigerator?
Refrigerated leftovers have limited safe storage time, and prompt cooling, clean containers, refrigerator temperature, and reheating practices all matter.

Overview
Cooked food does not become indefinitely safe once refrigerated. Microorganisms can survive cooking or be introduced afterward, and refrigeration slows growth rather than stopping it completely. Current food-safety guidance provides storage windows for many foods and emphasizes prompt chilling of perishable leftovers.
Chill promptly
Divide large quantities into shallow containers when appropriate so they cool faster, cover them, and refrigerate within the time limits in current food-safety guidance. Do not leave perishable food at room temperature for extended periods while waiting for it to cool completely.
Do not trust smell alone
Food can contain harmful microorganisms without obvious odor or visible spoilage. Labeling containers with the date and following storage guidance is more reliable than trying to judge safety only by appearance or smell.
