Kosher slaughterhouses in South America still use the barbaric ‘tie and raise’ method, which causes great suffering to animals before their deaths. Former Ashkenazi Chief Rabbi Yona Metzger (now in prison) said he is opposed to this slaughter method and has expressed his discontent. Link
PETA (People for the Ethical Treatment of Animals) described the method Jews use to slaughter animals as “prolonged suffering and nightmarish deaths.” This torture qualifies these debauched creatures to be sold as kosher.
Halacha (Jewish law) claims to minimize animals’ suffering. “The shochet kills the animal with a quick, deep stroke across the throat with a sharp knife. When performed properly, shechita appears all but painless and quickly renders the animal unconscious.”
