How long should leftovers be stored in the refrigerator?

Leftovers should ideally be stored in the refrigerator for no more than 3 to 4 days to ensure food safety. This time frame helps reduce the risk of foodborne illnesses that can arise from the growth of harmful bacteria. After this period, even if the food looks and smells fine, bacteria can proliferate to unsafe levels, making the food potentially hazardous for consumption.

The 3 to 4-day guideline is based on the understanding that refrigeration slows down bacterial growth, but it does not stop it entirely. Therefore, consuming leftovers within this period helps maintain both safety and quality. Proper storage techniques, such as using airtight containers and ensuring the refrigerator is at the correct temperature, can also help maximize the shelf life of stored leftovers.

When it comes to longer storage durations, while some foods might be safe for a little longer if frozen, the guideline for refrigerated leftovers specifically emphasizes the 3 to 4-day limit to prevent any risks associated with spoiled food.
