Abstract

We report an outbreak of listeriosis in Austria and Germany due to the consumption of ‘Quargel’ cheese produced by an Austrian manufacturer. At the time of writing this report, the outbreak was known to account for 14 outbreak cases in 2009, including four cases with lethal outcome. On 23 January 2010, the cheese product was voluntarily withdrawn from the market.
