  • How long does raw flounder last in the fridge or freezer? The precise answer depends to a large extent on storage conditions - keep flounder refrigerated at all times.
  • How long does raw flounder last after the sell-by date? After flounder is purchased, it may be refrigerated for 1 to 2 days - the "sell-by" date on the package may expire during that storage period, but the flounder will remain safe to use after the sell by date if it has been properly stored.
  • Unopened raw flounder may be kept in its original store packaging when refrigerating; to maximize the shelf life of flounder, do not open the package until ready to use.
  • How long can raw flounder be left at room temperature? Bacteria grow rapidly at temperatures between 40 °F and 140 °F; flounder should be discarded if left out for more than 2 hours at room temperature.
  • To further extend the shelf life of raw flounder, freeze; when freezing, place flounder in the freezer before the number of days shown for refrigerator storage has elapsed.
  • You can maximize the shelf life of flounder in the freezer by overwrapping the original store packaging with airtight heavy-duty aluminum foil, plastic wrap, or freezer paper or place the package inside a heavy-duty freezer bag in order to prevent freezer burn.
  • How long does raw flounder 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 - flounder that has been kept constantly frozen at 0°F will keep safe indefinitely.
  • How long does raw flounder last after being frozen and thawed? Flounder that has been defrosted in the fridge can be kept for an additional 1 to 2 days in the refrigerator before cooking; flounder that was thawed in the microwave or in cold water should be cooked immediately.
  • How long does flounder last in the fridge once it is cooked? Cooked flounder will usually stay good for 3 to 4 days in the fridge and 4 months in the freezer.
  • How to tell if raw flounder is bad? The best way is to smell and look at the flounder: signs of bad flounder are a sour smell, dull color and slimy texture; discard any flounder with an off smell or appearance.
