The dates which we imprint on our shelf-stable products are to inform consumers of their best “quality” dates, not “safety” dates. As per the U.S. Food and Drug Administration, if a product is stored properly, it should still be safe to consume after its “Best By” date. You may read more information on the FDA’s Food Facts. As an additional resource, you may also visit the USDA’s Shelf-Stable Food Safety page containing a food storage chart that lists how long food should keep if stored properly. According to this resource, low-acid canned goods, such as fish, should be consumed within 2-5 years of the production date.
