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