Eli5: Why isn’t carbon monoxide used in slaughterhouses to kill humanely?

(marked this as engineering because I’m not sure what it would fall under, biology maybe?)

I’ve seen in a documentary where they would put pigs in cages and lower them into a pit of CO2, but it doesn’t kill quickly and the pig would thrash around violently as it was slowly poisoned. Why not just use CO? it would kill humanely, and from what I understand, a lot of packaged meat is packaged in containers with CO to prevent spoiling, so there must be no safety issue with the meat.

So please explain, how over feeding an animal in an industrial environment to then kill it for mass consumption a humaine process?! Euthanaising a person that make a conscious choice of not wanting to live anymore is humane. Killing an animal that has a natural instinct to survive is not humane.
