Kosher certification is a formal approval given by a rabbinic authority or certification agency. Inspectors review the food’s ingredients, how it’s processed, and how it’s packaged. If everything meets kosher standards, the agency gives the product a kosher symbol—often a letter or mark on the packaging, like OU, OK, Star-K, or Kof-K. https://encoreresalestore.com/kosher-certification-a-guide-to-what-it-really-means/
