    I’ve had a number of occasions where I purchased meat and it was spoiled before the expiration date. At this point, I’m sick of putting my trust in big corporations and am trying to buy more foods produced locally.

      No matter where you buy it, expiration dates are only a general guide, and more of a “date of manufacture” note than anything. We evolved to detect potential food that has gone bad. Trust your senses. Look and smell should be enough to know what’s actually gone bad (which is usually past the “expiration” date). You can use something like this as a better guide for when food will actually go bad, but, again, trust your senses.

        I was buying it at Kroger, but got tired of meat being expired the first day I got it home, long before the expiration date. Now I buy from a rancher down the road. Re-reading my comment, it may have been unclear that I’m buying local to get better quality than I can get from big corporations.
