Kashrut is a set of dietary laws dealing with the foods that Jewish people are permitted to eat and how those foods must be prepared according to Jewish law. Food that may be consumed is deemed kosher, from the Ashkenazi pronunciation of the term that in Sephardi or Modern Hebrew is pronounced kashér, meaning "fit". Food that may not be consumed, however, is deemed treif, also spelled treyf. In case of objects the opposite of kosher is pasúl

Sometimes certifying rabbis act as their own mashgichim; such is the case in many small communities.

The Conference of European Rabbis (CER) is the primary Orthodox rabbinical alliance in Europe. It unites more than 700 religious leaders of the mainstream synagogue communities in Europe. It was founded in 1956 on the initiative of British Chief Rabbi Sir Israel Brodie, in order to revive the vanquished Jewish communities on the European mainland. Brodie was supported by the chief rabbi of France, Jacob Kaplan, the chief rabbi of Amsterdam, Aharon Schuster and the British Sephardic spiritual leader, Hacham Gaon. The first conference took place in 1957 in Amsterdam. As a result of the CER union with the rabbinates of the stronger western European orthodox communities, the vast majority of mainstream communities throughout the continent retained Orthodox affiliation and rabbinical leadership (with the exception of Hungary and Sweden where non-Orthodox groups had a strong prior presence). Even as some major Western European communities were deliberating joining non-Orthodox movements in the post WWII period, the strong rabbinical alliance was successful in ensuring an Orthodox rabbinate and securing the continuity of the orthodox rite even where the larger part of the membership had become secularized.

A kosher certification agency is an organization or certifying authority that grants a hechsher to ingredients, packaged foods, beverages, and certain materials, as well as food-service providers and facilities in which kosher food is prepared or served. This certification verifies that the ingredients, production process including all machinery, and/or food-service process complies with the standards of kashrut as stipulated in the Shulchan Arukh, the benchmark of religious Jewish law. The certification agency employs mashgichim to make periodic site visits and oversee the food-production or food-service process in order to verify ongoing compliance. Each agency has its own trademarked symbol that it allows manufacturers and food-service providers to display on their products or in-store certificates; use of this symbol can be revoked for non-compliance. Each agency typically has a "certifying rabbi" who determines the exact kashrut standards to be applied and oversees their implementation.
