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.

I’m sure they could but gassing lowers the quality of the meat due to the meat not being properly bled. Meat that hasn’t been bled properly takes minerally and more gamey. Suffocation stops the heart leaving the blood in the animal and very difficult to remove. Most slaughterhouses use the captive bolt pistol these days. It destroys enough of the brain to instantly make the animal “dead”. The animal doesn’t feel much and the more primitive part of the brain that controls the heart continues beating. The throat is cut and the blood is expelled from the body.
