The KOF-K emblem Kashruth symbol is the internationally recognized trademark of KOF-K Kosher Supervision, one of the foremost Kosher certification agencies in the United States. KOF-K has an international network of regional coordinators and Rabbinic representatives, all of them strictly Orthodox in their personal practice and synagogue affiliation. Regional coordinators are based in major American cities, Canada, South and Central America, Australia, Western and Eastern Europe, the Orient and Israel. These representatives conduct frequent visits to major manufacturers and their suppliers at every location where Kosher supervision is needed. Only those products and services meeting the strictest standards of Kosher law are permitted to display the symbol, which is protected under Federal law against unauthorized use. When consumers see KOF-K on a product, they know they are buying food that meet the highest levels of kashrus (Kosher law).
