Shelf Life Tips

  • How long does a can of clam chowder last once opened? The precise answer depends to a large extent on storage conditions - keep opened clam chowder refrigerated and tightly covered.
  • To maximize the shelf life of canned clam chowder after opening, refrigerate in a covered glass or plastic container.
  • How long does opened canned clam chowder last in the refrigerator? Clam chowder that has been continuously refrigerated will keep for about 3 to 4 days.
  • Is canned clam chowder safe to use after the "expiration" date on the package? Yes, provided it has been stored properly, the package is undamaged, and there are no signs of spoilage (see below) - commercially packaged clam chowder will typically carry a "Best By," "Best if Used By," "Best Before", or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the clam chowder will remain at peak quality.
  • To further extend the shelf life of opened canned clam chowder, freeze it: to freeze canned clam chowder, place inside covered airtight containers or heavy-duty freezer bags.
  • How long does canned clam chowder last in the freezer? Properly stored, it will maintain best quality for about 6 months, but will remain safe beyond that time.
  • The freezer time shown is for best quality only – canned clam chowder that has been kept constantly frozen at 0°F will keep safe indefinitely.
  • How long does canned clam chowder last after being frozen and thawed? Canned clam chowder that has been defrosted in the fridge can be kept for an additional 3 to 4 days in the refrigerator before using; clam chowder that was thawed in the microwave or in cold water should be used immediately.
  • How can you tell if opened canned clam chowder is bad or spoiled? The best way is to smell and look at the clam chowder: if the clam chowder develops an off odor, flavor or appearance, or if mold appears, it should be discarded.
  • Discard all clam chowder from cans or packages that are leaking, rusting, bulging or severely dented.
