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.
