If you stored the Thanksgiving meal in the fridge, Monday is the final day that most leftovers are safe to eat by.

The federal government’s online food safety resource says that Thanksgiving leftovers can only survive in the fridge for up to three to four days. After that, they can develop spoilage bacteria, which causes food to develop a bad smell or taste. However, leftovers stored in a freezer can last up to six months.

We love our leftovers, too. But this food safety expert tells us how long each Thanksgiving dish can last in the refrigerator before it spoils.

The U.S. Department of Agriculture says the Monday after Thanksgiving is the last day people can safely eat refrigerated leftovers.
