Things are starting to become slightly clearer as we near the point of discovery over the future of badger culling in England and beyond. Consultees to the online Defra Consultation questionnaire of 14th March were told this Monday (5th August) that an analysis of Consultation responses will be published in the autumn (Sept-Nov?) giving more time for policy development without badger culling. But there is no reason now to delay clarification on the big 56% lie surrounding the ineffective badger culls.
Notably, the NFU appeared fully taken in by the spin from the Animal and Plant Health Agency paper by Colin Birch and Defra, that badger culling ‘is working’. Birch et al. follows on from a paper published in Veterinary Record in 2022 that showed quite neatly how recorded bovine TB levels (recorded OTF-W incidence) peaked after the introduction of annual tuberculin testing in 2010 and began dropping in the High Risk Area from 2013 in some counties and generally by 2015. And, at a steady rate that did not increase once badger culling started (and that was more widespread from 2018), showing no evidence that badger culling had contributed to a slow decline of around 6% per year.
Steve Barclay, and previous Environment Ministers before him, had made wild claims of a culling benefit of around 50%, based on APHA parroting the claims made since the 1970s that this is the badger contribution to cattle TB. This has always been a poorly evidenced, lame and far-fetched claim, making a mockery of professional epidemiology.
Not to be fooled, Labour are onto the problem and have firmly labelled badger culling as ‘ineffective’ in their manifesto. They have highlighted the need to work with farmers and scientists which is now the helpful – but not very specific – new Defra mantra.
The Birch paper makes it quite clear in two places that the cause of the welcome decline in bTB first identified formally in 2022, cannot be attributed to any particular intervention, be it better testing, different tests and more frequent tests, better biosecurity or badger culling. It is just a crude before-and-after effort with no controls, showing what was already known in a slightly clunky way. This is no help at all, as Professor Macdonald at Oxford pointed out in his November 2023 ‘state of the science’ review. However, the unfortunately misleading abstract for the Birch paper transmutes opinion into ‘fact’, to give the casual reader a misinformed overview of the findings. How very CVO.
So what are we left with as we approach the time of Labour’s big reveal this month? Firstly, an increased interest in badger vaccination with Defra organising a media spree with its dutiful contractors to suggest a direction of travel that Natural England seem to think is appropriate.
Also, news from Oxford, where a 50,000 signature petition to the School of Biological Science, organised by the Oxfordshire Badger Group calling for increased academic engagement seems to be working. A response to the Torgerson et al. 2024 paper on the choice of models for analysis of the Randomised Badger Culling Trial data, published recently in Scientific Reports is imminent. The Torgerson paper wallowed rather oddly for 18 months in peer review, emerging little changed, so plenty of time for the RBCT folk to have prepared.
How the 50 something % cull benefit lie has been peddled in recent months and years:
Farmers Weekly: Badger culling policy reduces cattle TB by 56%, study shows
Farmers Guardian, Farming matters: Lord Robert Douglas-Miller – ‘The science is clear that the tide is turning on bovine TB’
Shrewsbury Conservatives, DANIEL KAWCZYNSKI MP MEETS WITH MARK SPENCER, THE MINISTER OF STATE FOR FOOD, FARMING, AND FISHERIES, URGING HIM TO TAKE TOUGHER ACTION TO REDUCE CASES OF BOVINE TUBERCULOSIS:
Parliamentary Question response from Mark Spencer: To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment her Department has made of the (a) effectiveness of badger culls in tackling bovine TB and (b) reliability of the TB test used to identify cattle for slaughter; and what estimate her Department has made of the (i) annual cost of bovine TB in Shropshire and (ii) level of bovine TB in that county.
