Since time in memoriam the Muslim Community have in this country have adhered to the ‘halal' tradition in many aspects of life.
The definition of halal is anything that is legal or lawful for Muslims. The term ‘halal' is applied to many facets of life; and one of the most common uses of these terms is in reference to meat products, food contact materials, and pharmaceuticals
In terms of meat, this can apply to what kind of animal is used (not pigs, for instance) and the way they are killed: an animal must be healthy, the butcher must make a recitation dedicating it to God, and the jugular vein, carotid artery and windpipe are cut with a single swipe from a sharp knife. As with kosher meat, the idea is that the animal dies immediately and the blood drains away. The head of an animal that is slaughtered using halal methods is aligned with the Qiblah. In addition to the direction, permitted animal should be slaughtered in the name of Allah (the Lord) and the person who is slaughtering should be a Muslim and he/she should be in a good mental condition and faith. Dhabiha is the name given to this prescribed method of animal slaughter. Many similarities exist between Kosher and Halal and are safe to be consumed by either faith. Kosher food is food prepared in accordance with Jewish dietary laws. In their most "biblical" form, Jewish Dietary Laws state:
Pork, rabbit, eagle, owl, catfish, sturgeon, and any shellfish, insect or reptiles are non-kosher. Other species of meat and fowl must be slaughtered in a prescribed manner to be kosher. Meat and dairy products may not be made or consumed together.
In India most meat is slaughtered Halal style except in the Sikh community which adopts the Jhatka method of slaughter. Thus Muslims and Sikhs refrain from eating meat in each other's homes as the style of slaughter differs. Most outlets and restaurants including fast food joints like KFC, McDonald's etc have halal style meat due to the large Muslim community.
