The same thing happend with Parma ham that wasnt manufactured in Parma didnt it?
In 1999, the Melton Mowbray Pork Pie Association, a group of seven local manufacturers, applied to the EU to have their products categorised as protected geographical indication (PGI). This would restrict the use of the name in much the same way that 570 other European foodstuffs, including Bayonne ham, mortadella, Cornish clotted cream, Scotch beef and Stilton cheese, have been granted protected status.
Think Parma ham and probably parmesan cheese is in the 570.
