Tips for storage. 1  Unopened canned salmon can be stored in the cupboard at room temperature for up to 3 years. 2  Once opened, remove salmon from the can, store in an air tight container in the fridge and use within 3-4 days.
Once it's been opened, your canned salmon should be treated like any other perishable food. Seal any leftovers in airtight bags or containers and keep it in your refrigerator for up to three days. If you've canned your own salmon, each jar might contain more than you'll eat during that three-day period.
