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