Keep raw pork ribs in their original wrapping and store them in the refrigerator, where they will keep for two to three days. Cooked pork will keep four to five days in the refrigerator. To freeze, wrap ribs well in plastic, foil, or butcher paper and store at 18F (0C) for up to ten months. Leftover cooked pork ribs keep in the freezer for one month. Thaw pork ribs in the refrigerator, leaving them wrapped. Ribs will take 8 to 10 hours to thaw, depending on the size and thickness of the pieces. Do not refreeze thawed pork ribs.
