In the production of Grana Padano Kosher, a "mashgiach" or Jewish supervisor must be present from the beginning of milking until the end of processing to ensure that only kosher raw materials are used. 
This supervision includes analysis of the production cycle, control of the milking process and milk collection, cheese production and control of labelling.
Kosher certification is not only synonymous with food suitable for consumption by members of the Jewish religion, but also with high quality food.
Careful attention to hygiene, careful selection of ingredients and constant checks at every stage of the process are some of the reasons why Grana Padano Kosher is an excellent product.
