Relative effectiveness of irish factories in the surveillance of slaughtered cattle for visible lesions of tuberculosis, 2005-2007.

Background: In Ireland, every animal is examined at slaughter for its fitness for human consumption. The aim of this study was to determine the relative effectiveness of factories in submitting and subsequently in having suspect lesions confirmed as bovine tuberculosis (TB) lesions during the years 2005-2007. This work provides an update from previously published data for years 2003-2004.
