anyone been to an abattoir? or for that matter, ever see how kosher and halal animals are butchered?
a lady I know works for the Canadian Food Inspection Agency. Her job is to monitor how food animals are killed and she enforces rules that are meant to keep the killing as 'humane' as possible. Every so often she will relate her experiences in trying to enforce the rules while working within the constraints of religious freedom at Halal and Kosher facilities. Sometimes, she is almost in tears when she tells me the stories.
In the west, some practices have been socially sanitized by hiding them from public view.
Having said that, I still like by steak medium raw; my lobster boiled, and my fish steamed.
