“Best By” dates on canned goods like corn, green beans, and tuna don’t indicate an expiration but the period when the product is at its peak quality. These dates are guidelines for freshness, not safety, and most canned items can be consumed well after the date, as long as they’re stored properly.

Canned corn and green beans can last 1-2 years beyond their “best by” date, maintaining safety, though you may notice slight changes in flavor or texture. Canned tuna, when stored correctly, can stay safe for 3-5 years, though quality may degrade over time.

To ensure safety, check cans for damage like rust or bulging, and discard if the food smells or looks unusual. When in doubt, it’s better to dispose of the product.

For optimal storage, keep cans in a cool, dry, dark place and ensure they’re undamaged. Rotate older cans to the front, and transfer any unused portions to a sealed container for refrigeration. These tips help prolong shelf life and maintain safety.
