SAFOSO conducted an external evaluation of the current surveillance system that demonstrates freedom from disease of Infectious Bovine Rhinotracheitis (IBR) and Enzootic Bovine Leukosis (EBL) in the Swiss cattle population on behalf of the Swiss Federal Food Safety and Veterinary Office (FSVO).
After the implementation of an automated sampling system in the largest slaughterhouses in Switzerland in 2017, the sampling was shifted from the farms to the slaughterhouse by the veterinary service. This relocation of sampling had a fundamental influence on the data basis, and thus an evaluation of the current system became necessary. SAFOSO assessed the sensitivity of the current surveillance system for IBR and EBL as designed and implemented by the FSVO. Furthermore, SAFOSO developed a spreadsheet-based sampling and sensitivity calculation tool and provided recommendations for further optimisation of the cost-effectiveness of the sampling program.
The sensitivity analysis of the surveillance system was kindly supported by Angus Cameron and his team from Ausvet.
