A Kosher Certificate is an official document issued by a recognized rabbinical agency. It proves that a food product or establishment follows Jewish dietary rules. These rules cover which foods are permitted, how they must be prepared, and how they are kept separate. For example, meat and dairy can never mix, and even the utensils and machinery used must be strictly separated. https://www.ganjingworld.com/news/1hpfp1gpqsn2GtEw06W11v3hf1vv1c/what-is-a-kosher-certificate-and-why-is-it-important
