Besides the fact that the canning process isolates the oxygen away from the entire can and upon being sealed, it’s kept fresh and to last a lot of time before consumption? This answer already is given by previous commenters, but that is because it is the real explanation xD

The answer is that it is possible to eat meat and fish years after production if it has been properly stored and preserved. This can be done through freezing, curing, canning, smoking, or dehydration. All of these methods help to extend the shelf life of the food and keep it safe for consumption for a longer period of time.

I would ask a question back: “why do you think that something that’s safe for 6 months would ever expire?”

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.

It’s sealed, also treated with preservative and salt, which makes bacteria hard to survive. Also because it’s sealed the food is protected from oxidization, which will dry it out and make it stale
