  • How long does a can of squash last once opened? The precise answer depends to a large extent on storage conditions - keep opened squash refrigerated and tightly covered.
  • To maximize the shelf life of canned or packaged squash after opening, refrigerate in a covered glass or plastic container.
  • How long does opened canned squash last in the refrigerator? Squash that has been continuously refrigerated will keep for about 3 to 4 days.
  • Is canned squash 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 squash 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 squash will remain at peak quality.
  • To further extend the shelf life of opened canned squash, freeze it: to freeze squash, place inside covered airtight containers or heavy-duty freezer bags.
  • How long does canned squash last in the freezer? Properly stored, it will maintain best quality for about 2 months, but will remain safe beyond that time.
  • The freezer time shown is for best quality only - squash that has been kept constantly frozen at 0°F will keep safe indefinitely.
  • How long does canned squash last after being frozen and thawed? Canned squash that has been defrosted in the fridge can be kept for an additional 3 to 4 days in the refrigerator before using; squash that was thawed in the microwave or in cold water should be used immediately.
  • How can you tell if opened canned squash is bad or spoiled? The best way is to smell and look at the squash: if the squash develops an off odor, flavor or appearance, or if mold appears, it should be discarded.
  • Discard all squash from cans or packages that are leaking, rusting, bulging or severely dented.
