Both Muslims and Jews have religious laws that determine the preparation of the food that they will eat. These kosher and halal laws dictate how slaughter shall occur, including the requirement for traditional slaughter to cause unconsciousness by a cut at the throat/neck by a person of religious faith.
In the case of the kosher slaughter, the slaughterman requires very specific training focusing on using a razor sharp knife devoid of any nicks. Following the kosher slaughter of animals, the animal is inspected internally with a special focus on the lungs.
