More on Why the OU

What is Kosher?

You may already be familiar with some of the more well-known requirements, but you may be surprised at the extent of some regulations. Kosher is a comprehensive system of food standards rooted in Jewish law that governs not only ingredients, but also how food is prepared, processed, and handled.

Under trusted certification such as OU Kosher, every step of production is carefully reviewed, from raw materials to equipment and facilities. This level of oversight helps ensure consistency, integrity, and trust, giving consumers greater confidence in the products they choose.
