A national cattle health surveillance system (CHSS) has been in place in the Netherlands since 2002. This system consists of several surveillance components: enhanced passive reporting, diagnostic test results and post-mortem exams, random surveys for prevalence estimation of endemic diseases and quarterly data analysis. This data-analysis component [Trend Analysis Surveillance Component(TASC)] aims to monitor trends and developments in cattle health using routine census data. The key monitoring indicators that are analysed as part of TASC all relate to cattle health and involve parameters such as mortality, fertility, udder health and antimicrobial usage. The challenges and lessons learned from developing this tool are discussed in this article. The TASC also allows to visualize trends in time, can be used to support or highlight signals that are detected in one of the other surveillance components and can provide warnings or initiate changes in policy when unfavorable trends in cattle health occur.
