Abstract

Free trade with animals and animal products requires transparency concerning health information of animal populations. On the basis of the bilateral agreement with the European Union (EU), Switzerland is obliged to document freedom from Aujeszky's disease (AD) in its pig population by conducting surveys on a regular basis. Such a survey was planned for the first time for the year 2001. In this context, it was evaluated whether additional pig diseases should be included in the survey. This article describes the evaluation procedure for the selection of pig diseases integrated in the survey 2001. Additionally, it reports and interprets the results of this survey. All of the 2537 farms and 41,719 blood samples were tested negative. Therefore, it could be documented with a confidence of 99.98% that the AD-prevalence in Switzerland is below 1%.
