Herd-based monitoring for tuberculosis in extensive swedish deer herds by culling and meat inspection rather than by intradermal tuberculin testing.
The effect of random slaughter and meat inspection as a tool to detect or eradicate tuberculosis in large, extensive deer herds in Sweden was evaluated. A computer spreadsheet model based on the Reed-Frost method was developed. Numbers of new infections and of infected deer slaughtered as well as probability of detecting tuberculosis or slaughtering all infected deer in a herd, were simulated. The model predicted that, given a 20% annual slaughter and that disease was introduced with one infected deer, the infection would be detected or eliminated in most herds (90%) after 15 years.
