Recent outbreaks in Switzerland
Listeria monocytogenes has caused a serious outbreak in the canton of Vaud in 1987. This lead to the death of 18 people out of the Mont-d’Or vacherin cheese amateurs, a local specialty cheese made out of raw milk. Since 2003, this cheese is made in Switzerland with pasteurized milk. Another outbreak happened in 2005 in the canton of Neuchâtel, which started from local tomes cheese. Two elderly died from it and two pregnant women lost their babies during the second outbreak.
