Spoiled pork typically has a soured smell. An odor generally occurs only after pork changes colors from pink to gray or brown, which is the first noticeable sign of spoilage. Fresh pork can be stored one or two days, and pork sausage for three to four days, in the refrigerator.
After cooking, pork can be stored in the refrigerator for seven days. Pork should be stored in a closed container to prevent contaminants and moisture from entering. To extend the shelf life of fresh or cooked pork products, place the items in freezer-safe storage bags or containers and freeze for up to eight months.
