Although it won't have any microbes in it (assuming the can is still completely sealed), it'll look and taste awful. Sealed cans only serve as a barrier to germs. They're not some kind of time-halting magic chamber. Chemical reactions still proceed inside. There's a reason manufacturers eventually started stamping "Best Before" dates on them. And no, it wasn't to fool people into throwing out perfectly good 10-year-old cans of food.

Yes, my concern is that anything with liquid inside will start to absorb metal atoms of the container's lining over time.

Did you eat the food from the 5, 10 year old cans?

No, it looked way too discolored and gross. And it wasn't even uniformly discolored.

Lol sometimes though I can't help but imagine what a can like that would be worth to someone living in Walking Dead times or some post apocalyptic scenario where food is really scarce.

I've eaten 60 year old crackers and energy pellets from a fallout shelter at my high school. I couldn't fathom eating something liquid that old though.
