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