Coxiella burnetii as zoonotic pathogen with special regard to food hygiene

In Hesse, Germany, bulk milk of farms producing raw milk cheese is examined by PCR for Coxiella burnetii yearly. In 2003 the pathogen has been detected unusually frequent. By means of two examples the hygienic measures are shown, which were initiated by the veterinary administration. To detect Coxiella burnetii means always the preoccupation with unsolved questions. It is particularly uncertain, whether there is a risk of oral infection for the human being. From the point of view of food hygiene, surveys are needed urgently to work out a risk assessment. Based on this a uniform risk management and a reasonable risk communication can be fixed.
