Kof-K

Kof-K, a Teaneck, New Jersey–based Kosher certification agency,[1] is one of the "Big Five"[2] kosher certification agencies in the United States.

As of 2010, more than one third of all food sold in the United States has kosher supervision,[3] 80% of it from one of the "Big Five."[2][4]

Its founder and rabbinic administrator was Rabbi Dr. Harvey (Zecharia) Senter, who died April 4, 2021 (אחרון של פסח).[5][6][7][8][9] It is now headed by two of his sons Rabbi Daniel and Ari Senter.[10]

While the Kof-K's certification is largely for products, they also certify kosher eateries.[11]
