While the keeper of an emergency underground bunker might have you believe SPAM® products offer eternal freshness, there is, in fact, a limit to their goodness. On the bottom of every can of SPAM® product you’ll find a "best by" date. This is the date Hormel Foods recommends using the product by. You’ll likely find yourself gobbling up the delicious meat inside the can long before that date. But if you find yourself sitting on a stock of SPAM® products during a zombie invasion, be sure to check the date before you enjoy.
