Wait for it.
I hope you have another 4 years to wait for them to show up Frank.Strange you should mention that. Last week I was down under the house changing out the filters on the a/c and I thought that I'd better check the emergency storage box that I keep down there for when we're hiding from tornadoes. Stuck right down at the very bottom of the crate was 1 can of each, both 4 years past their "use by" date.
I don't know whether to eat them, feed them to the dog, toss them in the trash or call in the Federal Emergency Response Clean Up Team to get rid of them.
As far as i am concerned that is a "best used by date" and has nothing to do with the safety of eating it. IMO, If the cans still sealed good and not blown out of shape, once opened if it looks good, and dont smell bad i would eat it before feeding it to an animal. But then again i aint near as picky as most folks.
