Shelf Life Tips
- How long does raw mackerel last in the fridge or freezer? The precise answer depends to a large extent on storage conditions - keep mackerel refrigerated at all times.
-
How long does raw mackerel last after the sell-by date? After mackerel is purchased, it may be refrigerated for 1 to 2 days - the "sell-by" date on the package may expire during that storage period, but the mackerel will remain safe to use after the sell by date if it has been properly stored.
-
Unopened raw mackerel may be kept in its original store packaging when refrigerating; to maximize the shelf life of mackerel, do not open the package until ready to use.
