Salmonella Dublin infections in cattle herds cause profit loss and despite a lowering in the number of contaminated herds in recent years, the numbers are still high in some regions. Therefore, Danish Dairy Board and Danish Veterinary and Food Administration together with research institutions have initiated an intervention campaign aiming to eradicate S. Dublin in cattle before 2014.
To achieve this goal it is necessary to develop new methods for more efficient surveillance of S. Dublin spreading in and between herds in order to control the contamination. Then, info about trade patterns, specific risk factors associated with herds etc. will be used to build up a risk-based detection scheme. In addition, possible improvement of diagnostic tools will be assessed for better detection of contaminated herds.
