Are those pesky "best by" dates getting you down, hinting that you should discard the product or suffer dire consequences? I'll let you in on a little secret. They are just guidelines for maximum freshness and have zero to do with product safety.
Example #1: This is spaghetti that I obviously purchased in April of 2017. This has been in kept in my cabinet in it's original packaging ever since. It has a best by date of December 6, 2018.
Now note the date I opened it...October 3, 2023. That is six and a half years, folks. Now you know. Don't worry if you find a package that has apparently gone walkabout and just now shows up for dinner. It's okay!
Need more proof? Example #2:
A can of corned beef hash.
What about the foods in your pantry? Most shelf-stable foods are safe indefinitely. In fact, canned goods will last for years, as long as the can itself is in good condition (no rust, dents, or swelling). Packaged foods (cereal, pasta, cookies) will be safe past the ‘best by’ date, although they may eventually become stale or develop an off flavor. You’ll know when you open the package if the food has lost quality. Many dates on foods refer to quality, not safety. See FSIS’ Shelf-Stable Food Safety fact sheet for more information.
