Halal slaughter involves killing the animal by cutting the trachea, the esophagus, and the jugular vein, and letting the blood drain out while saying “Bismillah allahu akbar”—in the name of Allah the greatest. Many people refuse to eat it on religious grounds. Many Christians, Hindus or Sikhs and Jews find it offensive to eat meat slaughtered according to Islamic ritual (although Jews are less likely to be exposed to such meat, because they eat kosher).

Idiot. The standards are so similar that Kosher meat is also considered Halal.
