Well, I know for a FACT that in my Army days I was eating canned food back from before I was born, LOL!
However, Hormel says of SPAM:
“The processing techniques utilized by Hormel Foods makes the canned product safe for use indefinitely if the product seal remains intact, unbroken and securely attached to a can that has been well maintained.”
So, pretty much forever; that’s the utmost in ‘sustainability’ IMHO, LOL! :)

Cool. I’m having a very tasty homemade Spam spread right now!
