--How to store the canned mackerel?

 --Carefully label all home canned or commercially canned food containers.  We recommend labeling purchase date (month & year) on can lid with marker.  Store all canned food in cool, dark, dry space away from furnaces, pipes, and places where temperatures change like un-insulated attics. Do not allow sealed cans or glass jars to freeze.Freezing changes food textures,and leads to rust, bursting cans, and broken seals that may let in harmful bacteria. Always store metal cans off of the floor, especially bare concrete.  Moisture can wick up to cans and encourage rusting. 

--What is the shelf life of canned mackerel?

--As a general rule, unopened home canned foods have a shelf life of one year and should be used before 2 years. Commercially canned foods should retain their best quality until the expiration code date on the can.  This date is usually 2-5 years from the manufacture date. 

--What should we take care before we open canned mackerel?

--Always use FIFO (First-in, first-out), meaning use your oldest cans first.  Before opening, discard any badly dented, bulging, rusty, or leaky cans or jars that have broken seals. Open cans or jars to view and smell contents. When opening, discard any can that spurts.  Discard contents (do not taste) if there is a strange odor or appearance.
