I have to admit – I am guilty of keeping some canned goods far longer than the expiration date. The reason being that I have a food storage pantry that I keep stocked, and often something will get overlooked. I operate on the understanding that anything canned cannot spoil, so it should be safe. However, I have opened older cans whose contents have discolored, or tastes weird, or smells kind of fermented. If it looks and smells okay, I am sure that it’s fine.
