BVA responds to Downs Study on badger culling

We have responded to a study by Downs et al assessing the effects from four years of badger culling in England on the incidence of bovine tuberculosis (bTB) in cattle.

The study, published in Nature Scientific Reports, investigated the effect of culling in the first three licensed badger cull areas – Gloucestershire, Somerset and Dorset – using data from 2013 to 2017.

Gloucestershire and Somerset saw reductions in bTB incidence rates in cull areas relative to comparison areas of 66 per cent and 37 per cent respectively after four years.  In Dorset, there was no change in incidence rates in cull areas relative to comparison areas after two years, but incidence dropped by 55 per cent in the same period in the 2km buffer zone around the edge of the cull area.  Matched comparison areas were similar but not identical.

James Russell, BVA Junior Vice President said:

“These findings are encouraging and offer further evidence that badger culling can result in significant reductions in the number of new cases of TB in cattle.  However, they come with the caveat that the data only relates to the first three cull areas, and the variability within these alone makes it too early to draw firm conclusions that culling will reduce incidence significantly in all 40 areas where it is now taking place. 

“BVA’s expert working group is currently considering all aspects of disease control looking at cattle testing, removal of reactors, compensation and control in other farmed animals as well as the culling and vaccination of badgers. The group will consider this additional evidence as we develop our new policy on bTB.

“We continue to support a comprehensive and evidence-based approach to tackling bTB, including the use of badger culling where there is a demonstrated need and where it is done safely, humanely and effectively as part of a comprehensive strategy. The best way of halting the spread of this devastating disease is enhancing our understanding of bTB and applying that evidence to the eradication process.”
