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