How long can leftovers be safely stored in the refrigerator?

Leftovers can be safely stored in the refrigerator for 3 to 4 days. This timeframe helps ensure that food remains safe to eat while minimizing the risk of foodborne illnesses. During this period, bacterial growth is kept at bay by the cold temperature of the refrigerator, but it's important to note that the safety window varies based on factors such as the type of food and how well it was cooked and stored.

After 3 to 4 days, the risk of spoilage increases significantly, and consuming these leftovers may lead to food poisoning. It's essential to also keep leftovers in airtight containers to reduce exposure to air and moisture, which can speed up spoilage. While some foods might last longer in terms of quality, this guideline is focused on safety.
