Differences between Halal and Kosher:
1. The Muslim slaughtermen usually pronounce the prayer on each animal at the time of slaughter. The Jewish Rabbi usually pronounce the prayer only once at the beginning of the slaughtering session.
2. In Halal slaughter, the animals may be directed to Qiblah, whereas no such direction during the kosher slaughter
3. In Kosher slaughter, the Rabbis examine the lungs and viscera of the carcass to check for discoloration and scars in these organs. In the Halal slaughter no such exams made and the health issues are usually left to the government officials and/or quality control personnel at the facility. This is why not every Kosher kill passes the approval, usually with an average of 50% or less of the carcasses may qualify for the Kosher stamp.
4. For the meat to be considered Kosher, only the front side of the animal (i.e. beef) is certified Kosher but not the hind quarters, because of the issue of de-vanning. In Halal, all edible meats and offal of the Halal slaughtered carcasses of healthy animals can be labeled Halal.
5. In the Kosher processing the meat is soaked in salt for about two hours then rinsed with water, to remove traces of blood from the meat. In the Halal processing the meat is not soaked in salt because only the flowing blood is prohibited from consumption by Muslims.
