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