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