I’ve always wondered how long I can keep food in the refrigerator. Sometimes I think I stretch it too long before tossing items in the garbage. According to the USDA, leftovers aren’t meant to stretch very long at all. They go on to say that cooked meals are only safe for up to 4 days in the fridge. After about four days is when that spoilage bacteria starts to kick in. Exactly how long it takes depends on other components. For example, citrus acidic sauce could preserve something longer. Also, a really cold fridge could buy you and extra day or two. Great. Now I know!
