Kosher certification is a process by which a company ensures that their food is kosher, or in other words, fit for consumption by observant Jews. Kosher refers to a religious dietary practice that is rooted in Jewish tradition. Contrary to popular belief, kosher food does not refer to Jewish cuisine. But today, consumers are concerned about more than just the kosher status of their food. Over 12 million American consumers choose Kosher food products for reasons related to health, food safety, taste, vegetarianism, lactose intolerance, and other dietary restrictions.
