List of Italian PDO cheeses
This List of Italian PDO/DOP cheeses includes all the Italian cheeses which have protected designation of origin (denominazione di origine protetta, or DOP/PDO), status under European Union regulations. All of the formerly existing "DO" cheeses (protected under Italian law) were registered in the EU as "PDO/DOP" cheeses during the course of 1996.
