Industry-led licensed badger control began in Somerset and Gloucestershire in 2013 with the aim of reducing the population of badgers and reducing the potential spread of TB between badgers and cattle.
This report assesses the incidence of TB in cattle after the first 2 years of licensed badger control in these 2 areas.
Updated report - the risk ratios and 95% confidence intervals for data prior to year 2 were corrected in appendix tables 8a and 8b. Appendix figure 5 which is created using these data has also been revised.
