- How long do frozen clams last? The precise answer to that question depends to a large extent on storage conditions - keep clams frozen at all times.
Properly stored, frozen clams will maintain best quality for about 12 months in the freezer, although they will usually remain safe to eat after that.
Are frozen clams safe to eat after the ‘expiration’ date on the package? Yes, if properly stored - commercially frozen clams 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 clams will remain at peak quality.
How long will frozen clams remain safe to eat? Frozen clams that have been kept constantly frozen at 0°F will keep safe indefinitely, as long as they have been stored properly and the package is not damaged.
How to tell if frozen clams are no longer good? If dry spots or discolorations have developed on the frozen clams, freezer burn has begun to set in - this will not make the frozen clams unsafe to eat, but it will harm the texture and taste.
