It can, but it needs some help.

By coincidence this particular can was a month past its best-by date, but that wouldn’t have mattered. The weak spot in the miracle that is Spam is the easy-open top, which can open a little too easily. I suspected that this one had a problem when I went to open the top and it nearly fell off in my hand. At some point it got bumped too hard and the seal failed. You have to be careful with them – I kind of wish they didn’t have the pull-off tops.
















































IMHO the stuff is bad even with a perfect seal. Way too much fat ‘n sodium. Glad you noticed it instead of eating it with the unpleasant aftermath.
Go bad? Spam, yes. Twinkies, no.
I’m not thrilled with the pull tabs either, they get in the way of a side cut can opener. If you can cut off the lid straight enough, happens about one time in three, then once you wash the can thoroughly it makes a pretty good small storage caddy.
I don’t know if you use any tomato paste but if you do watch out for them as well. With time their acid content can get through the lining and then the can. On those the best by dates are actually pretty accurate.
Remember when cans had a “key” you broke off and then used to peel the top off?
The pull top cans are a disaster for long term storage of fruits and vegetables. I do remember cans with keys and they were a lot more secure.
Canned corned beef still uses a key for some reason.
Span going bad… Well, that’s one thing I’ve not encountered yet. Spam and corned beef don’t stay on the shelf long enough to go bad.
The corned beef I see in the stores (with the can key) are all made in South America, Argentina I think. Agree with ya about the modern pull tabs on cans being a weak point.
Bear? I had some Twinkies go bad, from my cache of them and Zingers after the Great Twinkie Shutdown of 2012 (just in time for the Mayan Apocalypse). I discovered it when I reached in for a treat and found it had gotten fuzzy inside it’s “individually sealed for your protection” wrapper, as had about four or five others. I tossed those and moved the rest to a colder location, in hopes of preventing further losses.
Yes mattexian, for a while there we were living in a post-Twinkie world.
