Shelf Life Tips
- How long does frozen mackerel last? The precise answer to that question depends to a large extent on storage conditions - keep mackerel frozen at all times.
-
Properly stored, frozen mackerel will maintain best quality for about 9 months in the freezer, although it will usually remain safe to eat after that.
-
Is frozen mackerel safe to eat after the expiration date on the package? Yes, if properly stored - commercially frozen mackerel 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 frozen mackerel will remain at peak quality.
-
How long will frozen mackerel remain safe to eat? Frozen mackerel that has been kept constantly frozen at 0°F will keep safe indefinitely, as long as it has been stored properly and the package is not damaged.
-
How to tell if frozen mackerel is no longer good? If dry spots or discoloration have developed on the frozen mackerel, freezer burn has begun to set in - this will not make the mackerel unsafe to eat, but it will harm the texture and taste.
