Shelf Life Tips

  • How long does a can of water chestnuts last once opened? The precise answer depends to a large extent on storage conditions - keep opened water chestnuts refrigerated and tightly covered.
  • To maximize the shelf life of canned water chestnuts after opening, refrigerate in covered glass or plastic container.
  • How long do opened canned water chestnuts last in the refrigerator? Canned water chestnuts that have been continuously refrigerated will keep for about 1 week.
  • Are canned water chestnuts safe to use after the "expiration" date on the package? Yes, provided they have been stored properly, the can or package is undamaged, and there are no signs of spoilage (see below) - commercially canned water chestnuts 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 water chestnuts will remain at peak quality.
  • Can you freeze canned water chestnuts? Canned water chestnuts do not freeze well.
  • How can you tell if opened canned water chestnuts are bad or spoiled? The best way is to smell and look at the water chestnuts: if the water chestnuts develop an off odor, flavor or appearance, or if mold appears, they should be discarded.
  • Discard all water chestnuts from cans or packages that are leaking, rusting, bulging or severely dented.
