Roughly 3,000 tons of counterfeit Emmentaler cheese is produced each year that is not made in Switzerland. The counterfeit trade in the cheese makes up to 10 percent of the legitimate market.
Most of the counterfeit cheese is found in Italy, according to the organization Emmentaler Switzerland.
Emmental cheese is also commonly known as Swiss Cheese.
