Tips

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