Cooked pot roast storage

According to food safety guidelines, a cooked pot roast typically lasts for 3 to 4 days in the refrigerator when stored properly in an airtight container.

Since your pot roast was cooked 4 days ago, you should inspect it carefully for any signs of spoilage, such as an off odor, unusual color, or a slimy texture. If you notice any signs of spoilage, or if you are in doubt, it is safest to discard it.
