Canned foods don’t make you sick, they can only change in flavor and quality and nutrition, but they are still safe to eat, with only the normal canned food rules applying, in other words, as long as the can is still sealed and not bulging, eat it.

Having eaten startlingly old C-Rations in the early Eighties- I concur. They only made me think I was sick.

I like C-rations and preferred them to the early MREs, which have since improved, during the Vietnam war we were eating c-ration meals with cigarettes with them.
