I thought halal slaughterhouses were illegal in the USA, due to the horrific way they torture & kill the animals...(it's a muslim  deal,  they enjoy inflicting enormous pain on other living things).  Animals are NOT stunned before death, and are fully conscious as they are killed.  Used on them are knives, hanging hooks, blowtorches, kicking, punching, stomping, etc.  It's truly barbaric.
