How long do canned foods last past their expiry date?

As long as the can is not punctured, they will be safe to eat for decades. They might not taste very good though.

You should toss them 1 year before because botulism.

the container is leaking, bulging, or swollen
the container looks damaged, cracked, or abnormal
the container spurts liquid or foam when opened
the food is discolored, moldy, or smells bad

I was going to say, depending on acidity, until the bpa lining becomes compromised. Before that, pretty much indefinitely as others have alluded to. I'm not even sure anymore.

Length of time would have no effect on botulism toxin being produced or not. If live spores are present and the environment is suitable (sealed anaerobic, non acidic contents) enough toxin to kill you and hundreds of others will be produced in a few days. If no live spores are present they won't spontaneously appear in a sealed can 20 years later.

This, but the opposite.

You can kill botulism spores with a pressure canner though. 1 bar of pressure should reach 250F, which is enough to inactivate even the spores.

If you're within a year or so of the expiration date and none of these symptoms are present, I think you'd be fine. But most canned foods are so cheap, just throw them away if you're concerned unless it is an emergency.

So, a sealed, anaerobic can containing live botulism spores won't produce toxins until after some arbitrary exp date? And if there are no live spores present in an anaerobic sealed can, they might magically, spontaneously appear and start producing toxin at some point past the exp date? Were you retards home schooled by evangelicals?

>>11878428
True, but even industrial canning, albeit rarely, malfunctions and fails to kill the spores. My point is if it was canned properly, botulism will not develop no matter how old it is since no live spores were present and if it was canned improperly with live spores remaining, the toxin will be produced in enough quantity to kill you long before the exp date.

Sounds right to me.
