In 1935, today’s food industry – diversified corporations, complex production processes and international brands – was just beginning to take form, with the marketing strategies that have propelled the growth of its greatest companies.

Among its target markets was the growing Jewish community, greatly expanded by the early 20th century’s influx of Eastern European immigrants. To meet their religious requirements, companies turned to OK Kosher Certification, newly- founded by chemist and Kosher expert Abraham Goldstein. OK Kosher Certification quickly gained a reputation for technical expertise and customer service, establishing a place at the leading edge of Kosher supervision.

As the food industry expanded through the next decades, OK continued to prove its ability to apply the uncompromising standards of tradition to industrial development.

In the 1960’s, as industrial technologies and corporate development took great leaps forward, Rabbi Berel Levy – profiled in the NY Times as “both a spiritual leader and a man who readily understands what food processing is all about” – took the helm of OK Kosher. A tireless innovator with a truly rare combination of vision, organizational skill and technical acumen in Jewish law, food science and manufacturing, Rabbi Levy propelled the OK to international recognition.

In 1977 – after seven years of’ intensive study in Israel – Rabbi Don Yoel Levy joined his father at OK Kosher Certification. Assuming its leadership a decade later, Rabbi Don Yoel Levy has achieved international renown as an authority on Kosher food. Under his direction the OK has utilized the revolutionary developments in information and communications technologies to establish the most advanced, reliable Kosher supervision available to the food industry.

With more than 380 Field Representatives in over 72 countries across six continents – and a ground-breaking digital information system more than 15 years in the making – OK Kosher Certification continues at the forefront in offering the highest standard in supervision services to food companies around the world.
