> The only slaughterhouse job worse than eviscerating animals is cleaning up afterward. The third-shift workers, as the cleaners are often called, wade through blood and grease and chunks of bone and flesh, racing all night to hose down the plant with disinfectants and scalding water. The stench is unbearable. Many workers retch.
I should mention that I worked in New Zealand so YMMV, but this was never my experience. There was cleanup with high pressure hoses throughout the day, most of the time cold water to save power. No animals were eviscerated, they want as little wastage as possible; if it isn't consumable by humans it can be sold as animal food. The animals were knocked out (like a strong taser) before they were killed. Nobody was retching; it smelled bad (particularly pigs) but you get used to in the same way you adjust to any bad smell.
I agree with the comments here that we need to move quickly to lab-grown meat or a vegetarian diet. But I have to acknowledge that the abattoirs I worked at acted as responsibly and humanely as possible
Very different than the US
