Expiration & Storage Tips
When does canned salmon expire?
Unopened canned salmon can last anywhere from 2 to 5 years beyond the date printed on the can when kept in a cool, dark place, like a pantry. The high heat used in commercial canning kills bacteria, yeasts, and molds, which could otherwise spoil the food. When using canned salmon, it’s best to consume the entire contents once opened, but if you have leftovers, they'll last for up to 3 days in a sealed container in the fridge. As for freezing, it's usually not necessary given canned salmon's long shelf life, but if opened and properly stored in an airtight container, frozen salmon can last up to 6 months.
How do you tell if canned salmon is bad?
While canned foods have a long shelf life, they can still go bad. Signs that canned salmon has spoiled include a swollen or leaky can, or an unusual smell when first opened. As for the salmon itself, if it's slimy, discolored, or if it tastes off, it's best to discard it. As a rule, when in doubt, throw it out.
Tips for storing canned salmon to extend shelf life
• Store unopened cans in a cool, dark pantry where temperatures remain stable.
• Once opened, transfer any leftover salmon to an airtight container and store it in the refrigerator. Finish it off within a few days.
• If you need to freeze opened salmon, put it in a freezer-friendly bag or container and be sure to squeeze out as much air as possible to avoid freezer burn.
• Don’t forget to label your cans with the purchase date, or your containers with the date you froze it. This will help ensure you use your salmon while it's still at its best.
• Avoid storing cans in areas where they can be exposed to freezing temperatures or high heat, which can affect the quality and safety of the food.
