Some canned foods will go bad past their expiration date. One in particular is canned condensed milk. Also oil will go rancid, as will shortening in the can.
I did eat a can of c-ration chocolate cake back in the 70's that was3 years old and it was good. I still have a couple of cans in the basement somewhere. I should find one and see if it still is edible.
