Here's an example of halal slaughter Brazil style

"Minerva, the third biggest producer and exporter of beef in Brazil, has a dedicated halal slaughter plant. Here cows are ushered into an enclosure where they are struck on the head with a hammer and collapse on the floor — dizzy but alive. The slaughterer, a Sudanese Muslim man, utters the word "Bismallah" (in the name of Allah) before he cuts their jugular veins with a sharp knife so the animals die quickly and their blood drains out in compliance with halal customs."
