If the piece of fresh cut pork tenderloin is well-wrapped, it can stay in a freezer that is at a temperature of 32 degree Fahrenheit for about 6 months. Before storing the fresh meat in the freezer, it can be wrapped in heavy-duty aluminum foil, specially coated waxed paper or a plastic bag.
If storing a fresh cut of pork tenderloin in the refrigerator, it should keep for up to 4 days. However, if the meat is being cooked at a later date, then it should be placed in the freezer until it is ready for use. To thaw frozen pork, it is a good idea to keep it in the refrigerator until it is completely defrosted. Depending on the size of the cut of meat, it can take up between from 3 to 5 hours per pound if it is a small tenderloin roast.
