Canned goods last a long time because the canning process kills bacteria and other microorganisms that cause food to spoil. This means that the food inside can stay good for a really long time, even up to several years. It’s safe to eat because it’s sealed and protected from contamination. Just be sure to check the expiration date and don’t eat it if the can is damaged or swollen.
Because as long as the can itself is in tact, in theory anything inside it is also sterile. The product is packaged, then heat treated much the same way your grandma might’ve canned her garden vegetables at home. The superheated canning process kills off bacteria, fungi and spores inside the can, leaving a sterile environment so long as the can doesn’t get opened to air. You could accomplish the same thing at home with some meat and a pressure cooker.

Food “goes bad” for 2 reasons
1) Bacteria or mold eats it (rott)
2) It reacts with stuff the air
Canning basically takes both of those out of the equation. If the can stays sealed, nothing can get in. No air, no mold, no nothing.
The only way canned food really “goes bad” is if the food itself breaks down, and that’s not really dangerous. It might not taste great, but it’s safe to eat.
