I came across this when looking up the real shelf life of canned foods. From my personal experience I have eatten canned foods that were 5 years past expiration date. These canned foods were kept in a dry mild climate. The can had no visible signs of dents or rust. When opening it, it tasted just fine.

I am no expert, but when it comes to stock piling foods, I am worried we might be throwing good foods away. Low-acidic foods like tomatoes, carrots, potatoes, pumpkin, and peas might last even longer.
Bacteria growth often will buldge the can. However from what I have read this is rather rare. You can also do a smell and taste test.
