Tragic: Teenager dies after years in a coma; Cause: Raw milk cheese
The cheese specialties Appenzeller, Emmentaler, Parmesan, Allgäuer mountain cheese, and others are usually made from raw milk, which may have been filtered at most. After a long, 9-year suffering in a coma, the Trentino teenager Matthea Maestri has passed away, who was suffering from an EHEC infection with kidney complications. He had eaten the incriminated cheese when he was 4 years old! - An Italian court had convicted two managers of a dairy farm as well as those responsible for the cheese dairy for negligent bodily harm in this case. According to RAI, the cheese came from a dairy in the South Tyrolean Nonstal.
