  • How long does an unopened package of string cheese last in the fridge? The exact answer to that question depends to a large extent on storage conditions - keep string cheese refrigerated at all times.
  • To maximize the shelf life of string cheese, do not open the package until ready to use.
  • Properly stored, an unopened package of string cheese will last for about 1 week after the Sell By or Best By date on the package.
  • To further extend the shelf life of unopened string cheese, freeze it; when freezing, place string cheese in the freezer before the number of days shown for refrigerator storage has elapsed.
  • To freeze string cheese, tightly seal original packaging and place in freezer; if freezing for longer than 2 months, place package inside a heavy-duty freezer bag in order to prevent freezer burn.
  • How long does string cheese last in the freezer? Properly stored, string cheese will maintain best quality for about 8 months, but will remain safe beyond that time.
  • The freezer time shown is for best quality only - string cheese that has been kept constantly frozen at 0°F will keep safe indefinitely.
  • How can you tell if string cheese is bad or spoiled? The best way is to smell and look at the cheese: if cheese develops an off odor, flavor or appearance, it should be discarded; if mold appears, discard all of the string cheese.
