A couple months ago I popped open a can of tuna with BB date of 2013. Made some tuna salad sandwiches. They were fine.
Yep.
I opened a can of Tuna in 2011 that was dated 2000.
No problem.
It’s no different than the canning done on farms.
less than 100 people per year die of Botulism.
While it probably isn’t comfortable if you experience Botulism, the only cure for it is....Wait.................Water...Lots of it...
You should be rotating your inventory.
Let's say you want a five-year insurance policy - i.e., five years' worth of "protection" against "Crazy Times" lasting five years.
That means that you buy, all at once, as much of the given foodstuff as you would normally consume over a course of five years.
You then immediately begin consuming your stockpile - and simultaneously replacing each individual can of tuna or what-have-you as you consume it.
For the following five years, you are consuming food that is gradually growing older. By the end of that 5-year period, you are consuming food that is 5 years old. Here, you have reached a plateau. If you continue with this system, you will be eating five-year-old food for the rest of your life - but you will always have a five-year supply of foodstuffs on hand.
But then, you probably know all of this already!
