The U.S. Food and Drug Administration says it is safe to store a pork chop in the freezer for up to four months. These guidelines are the same for both pre-frozen and fresh pork. After this, bacteria or other potentially harmful elements might grow on the meat.
Keep the Cut in Mind
Using a four-month limit for all pork would be rather conservative. The pork chop is the smallest and therefore the quickest to go bad. An entire pork roast, according to the FDA, can keep in the freezer for up to a year or longer. The FDA also notes that their guidelines are applicable for "taste and quality" concerns. Frozen pork can be kept safely in a fridge possibly for longer than a year. To be safe, check with your butcher before freezing.
Using four months as a conservative estimate follows the FDA rules for all types of pork. If you are freezing a whole pig, it may keep for longer.
