The word kosher means proper or acceptable, and it has informally entered the English language with that meaning. But kosher laws have their origin in the Bible and are detailed in the Talmud and the other codes of Jewish traditions. They have been applied through the centuries to ever-changing situations, and these rulings, both ancient and modern, govern OU kosher certification.
Kosher Certification is the stamp of kosher approval by a rabbinic Agency verifying they have checked the products’ ingredients, production facility, and actual production to ensure all ingredients, derivatives, tools, and machinery have no trace of non-kosher substances. The Kosher Certified symbol assures consumers that both the actual product and its production adhere to all Kosher Law requirements.
