The Failed Badger Culls – a brief history and why the fight is not yet over.

Featured

Posted on by

Episodic and patchy badger culling has been taking place in England over the last 50 years in an attempt to influence the bovine TB epidemic in cattle herds. And there have also been several ‘experimental’ badger cull trials over that time, the largest of which was the Randomised Badger Culling Trial (1998-2005). The current ‘proactive’ intensive badger culls, where a guesstimated 70-95% of the badger population is killed, began in 2013. We have now had 10 full years of intensive badger culling across the High Risk Area, with over 210,000 badgers reported killed. There have also been experimental badger culls in TB hotspots in at least two places in the ‘Low Risk Area’, where the aim is to kill 100% of the badgers. Killing is now done largely by free-shooting, which is deemed inhumane by the British Veterinary Association because of the cruelty involved.

How is disease control going?

With variations between areas, the general trend for the bovine TB burden in cattle has been downward. However, this decline in bTB cannot be linked to badger culling as in almost all areas bTB rates levelled off and began falling in response to the move to annual cattle testing in 2010, before badger culling began.

Importantly, there has been a further increase in the frequency of cattle testing for bTB over the same period as culling has been taking place, which has begun to remove infected cows slightly more efficiently. Cattle are now tested every 6 months using the tuberculin skin (SICCT) test, and additional testing using Gamma Interferon tests have been introduced to  help remove more of undetected but infected cattle. It is this increase in frequency and efficacy of testing that has been reducing the rate of infection, not badger culling.

Analysis shows no difference in disease decline between culled and unculled areas

The most recent peer-reviewed and pubished analysis of the efficacy of badger culling has shown that there was no detectable difference in disease reduction between culled and unculled areas between 2013 and 2020. All that DEFRA has done is make a crude claim that badger culling works, based on reports  and data that it has  refused to publish or make available for many years and for spurious reasons.

What’s happening now?

Despite the near-complete government news blackout on badger culling, it is still very much government policy. It continues in 60 zones this year, reducing in number by around a third each year until 2025 when the final 23 culls will fizzle out. Natural England have once again authorised badger culling licences for autumn 2023 (announced September 7th). This will mean that up to 26,000 largely completely healthy badgers will be shot dead this year under their watch.

What are Defra’s plans for badger culling in the future?

New report on ‘epidemiological culling’

Despite headlines back in 2020 suggesting that badger culling was to be phased out, the likelihood is that Defra is being cajouled by industry to introduce a new badger culling policy. We understand that a consultation this autumn might seek views on a ‘reactive’, or so-called ‘epidemiological’ culling policy, a method with the core approach banned by government in 2003..

If implemented, this policy would seek to kill 100% of badgers in what are being called bTB ‘cluster’ areas. Although such culls are described in new policy as for ‘exceptional use’ only, it is possible or even likely that they will be implemented wherever bTB is found in cattle and where farmers want to kill badgers. Minette Batters, President of the NFU, has made no secret of her wish to remove badgers from livestock farmland completely, and Defra listen to the wishes of the NFU. The policy does indicate vaccination for any badgers that remain following culling, but this is a policy that clearly continues to attribute significant cattle infection to badgers. This, despite consistently growing scientific evidence for this being extremely unlikely, with weak, equivocal or even manufactured evidence keeping that sentiment alive.

Disease breakdowns continued in Cumbria despite 100% of badgers culled

A trial of this new ‘epi-culling’ approach has been taking place in Cumbria since 2018. Despite eliminating the entire badger population over an area of around 90 sq.km. or more, herd incidents with persistent infections remain unresolved. Bovine TB infection is persistent because it comes from within the herd and from traded stock. There is no credible epidemiological route for infection from badgers. This is useful as a model of why government policy is badly flawed and misguided.

What can we do to stop this?

Years of campaigning by numerous organisations and individuals has so far;

  • Led to legal challenges in the High Court of aspects of the welfare consequences of, scientific justification for, and potential ecological effects of badger culling
  • Challenged the certainty of the science being used to justify badger culling with peer-reviewed analyses
  • Lobbied MP’s repeatedly
  • Organised over 50 rally’s and marches
  • Produced many petitions of up to 300,000 signatories
Protesting outside High Court London

But Defra have not listened or even significantly engaged with those  opposing badger culling. They are listening to the NFU, the big landowners with a powerful voice, and vets who put their own interests and industry before environment, biodiversity & animal welfare. 

The increasing public awareness of climate change impacts and the immediate threat they pose have led to urgent calls to reduce meat and dairy consumption. This in turn should make government take a radical look at the farming industry in the UK, and the policies it is supporting that damage our natural environment. It looks like an impossible task with a government that has no qualms about supporting and subsidising the fossil fuel industry and counts many large land-owners with vested interests amongst its MPs.

Will an election in a little over a years’ time make any difference? Politician’s convictions seem to be increasingly fragile approaching a election, where the importance of green issues to the electorate may be unclear or even antagonize a proportion of it. Whilst polls show that voters rank the environment among the concerns of greatest importance to them, the Uxbridge byelection showed that these issues require careful handling.

Effective caps are needed to block wastefulness and overexploitation of limited resources for trivial activities and inefficient processes.  If candidates want your vote at the next election, the political parties & their candidates need to commit to a comprehensive overhaul of farming and environment policies. It is vital to make it crystal clear to them how important these issues are, or they will not commit to addressing them urgently. We may be stuck with badger culling and policies that continue to deplete our natural resources until it is too late to prevent catastrophic damage. Badger culling is just one more symptom of everything that is wrong in environmental protection in England in recent decades. Strong action is needed right now to change the way government thinks and acts. Everyone has a role to play in ensuring that those in power, and those seeking power, know how important environmental issues are, and how their response to them will affect the way we vote. 

 

 

 

 

What is going on with bovine TB in north Wales?

Posted on by

Some observers may have noticed bovine TB breakdowns figures for Wales have levelled-off in recent years. For the first time in a long while they are showing a divergence away from the progress of herd breakdown trends that until recently was largely parallel with England.
See the data here. 

And here:

Since 2021, north Wales has experienced an uptick of bovine TB breakdowns in two areas in north Wales, which is causing a levelling of national decline. Looking at the genomic (spoligotype) data indicates that this upsurgence of disease originates from cattle movements from the English border counties of Shropshire and Cheshire, dating back to 2017. Radiating local movement of disease (local trading) within the ‘Low’ and ‘Intermediate’ TB Areas North, in Wales, has pulled down the overall progress compared with England.  Wales introduced enhanced measures and increased testing sensitivity several years before England, resulting in its downward trend. But this has now been held back and it has nothing to do with badger culling.

While bTB control has been compromised in two areas of Wales, in 2022  England saw a welcome steeper decline in 0TF-W  breakdowns as the use of 6-monthly SICCT testing and gamma interferon to better identify infected cattle began to take effect. Gamma testing raises herd testing sensitivity from around 80% (of the SICCT test) to perhaps  90% or more, halving the numbers the tuberculin test misses but has around 4% false positives. This is one reason why 6-monthly SICCT testing has been preferred as it also detects more than a single annual SICCT test. The additional 6-monthly SICCT tests were introduced in Shropshire and Staffordshire from March 2021 and in the rest of the HRA from January 2022. Defra have had issues updating their data recently, but it now appears that  in the HRA cattle tests increased from around 4.61 million 2021 to 5,44 million in 2022 an increase of approaching 20%. 

However, APHA data shows how, alongside, gamma testing bit into the main  driver of disease – persistent herds, often with large numbers of cows and cow sales each year and infecting many new herds each year through local and auction sales. The big breakthrough came in 2019 with over a quarter of a million gamma tests across the HRA and Edge with a 30% drop in persistent herds across the HRA and Edge. 

Further, for 2019, Defra followed the example of the Welsh Government and applied a 50% reduction in compensation for animals moved into a TB breakdown herd that were subsequently removed as TB reactors or direct contacts before the herd regained OTF status. Gamma testing was used in England at considerable levels from 2018-2022 in the HRA, and the disparity became more visible from 2020 as Wales became infected from the English Edge Area.

Peer-reviewed analyses show that in England  there is no sign of benefit in the HRA from badger culling. The rate of decline of bovien TB disease prevalence in England’s High Risk Area (HRA) now matches the level of fall of 20% per year seen in the 1960’s, when the disease was quickly brought under control using cattle based measures. Had gamma testing been introduced earlier as in Wales and the Republic of Ireland, the English epidemic would have been well under control by now.

Six-monthly SICCT testing and use of Gamma testing will disclose more infected cows that escape the testing system and bring bovine TB down, but may not finish the job. A more sensitive and specific  blood test such as Actiphage will be needed to do that. Cattle vaccination may also play a role too but with a disciplined approach to testing, may be avoided.

BBC misleading again on badger culling?

Posted on by
10 years on and the BBC repeats acknowledged errors, misleading the public on badger culling

On 13th May 2013, the BBC posted an article entitled “How did the Irish badger cull play out?”.

On 1st June 2013, this report was produced on the impact of the badger cull in Ireland.

Both of these pieces were by BBC Journalist David Gregory-Kumar (DGK). Both these stories, and others beside support the controversial government view that badgers play a significant role in bovine TB control in cattle. Complaints to the BBC by ecologist Tom Langton eventually led to the following BBC ruling:

Given that both the statistics and scientific studies about the link between badger culling and bovine TB levels were inconclusive, the Committee examined whether the article had used clear and precise language to make this apparent to the audience. In doing so, it observed that the badger cull had become a highly divisive issue with those for and against the cull using the findings of different trials to bolster their respective causes and so it was essential that the BBC provided the greatest clarity possible on the subject.

In this context, the Committee believed that the language used in the article had not been sufficiently precise as it suggested that the badger cull might be a factor in helping control the disease when this was scientifically unproven. It considered that, while the data did show a decline in the number of cattle infected with TB in Ireland, there was no conclusive evidence to show that the badger cull had been categorically responsible for any of this decline and so it was inaccurate to say that, along with other measures, it can help control the disease.

Exactly the same error was repeated by the same journalist in a piece on BBC’s Farming Today on July 4th 2023, 10 years later, this time regarding the English culls.  DGK plays a clip in which farmer James Griffiths says “badger culling has undoubtedly made a difference, no one can deny it” DGK follows this by saying “the latest data seems to support this.” The latest data does not support this. The latest data shows bTB falling generally because of cattle measures but the role of badger culling, if any, is not known. Why is DGK doing this we wonder?

DGK forgot to mention that there were more bTB breakdowns in Gloucetreshire pilot 1 area in 2022 than in 2013 when badger culling began.

And again, in ‘Has a decade of badger culling worked?’ published on the same day, the bias continues.

There is no mention of the peer-reviewed paper published last year by Vet Record, “Analysis of the impact of badger culling on bovine tuberculosis in cattle in the high-risk area of England, 2009–2020” by Tom Langton, Mark W. Jones, and Iain McGill. This examination of government data obtained over a wide area and a long time period failed to identify a meaningful effect of badger culling on bTB in English cattle herds.

Defra has failed to publish any analysis that shows that badger culling has produced any disease benefits since its much caveated publication in 2017, which was based on limited data over a limited period of time.  DGK says that to show that badger culling is working you would need to “compare areas with a cull to those without and we can’t do that because the culls are now everywhere.” This is not the case. Defra holds all the data for all farms, culled and unculled, and it would be a relatively simple job to extract data from culled farms and compare them with unculled farms using a range of available techniques. They may have already done this. If not why not? 

Overall, the bTB disease figures from Wales (where there is virtually no culling) and England (where 210,555+ badgers have been culled) have been very closely aligned. This is, perhaps, the best evidence that badger culling plays no role in bTB control.

Incidentally, Jeff Sim at Staffs Wildlife Trust who was interviewed said that he was vaccinating badgers to reduce bTB in cattle. But in fact such a relationship is not known and is purely speculative. Wales gave up on vaccinating badgers a long time ago.

Finally DGK’s idea that badger cull benefit lasts 4 years is not solid science. The confidence intervals on that old data indicate nothing scientifically significant. The late statistician David Cox who was involved with the RBCT is reported to have said at a conference later that he wished they had presented it as trends rather than as significant as the RBCT confidence intervals were also mostly very large.

The real story is that 6-monthly cattle testing in the High Risk  and Edge Area are now starting to work.

Out & about in Oxford this week

Posted on by

Badgers have been speaking up for themselves in Oxford this week. They  have been making their presence felt, raising awareness of the current government badger cull policy, and explaining what the future of badger culling could look like in Oxfordshire. Now that Minister Therese Coffey has thrown doubt over government previously stated intentions to stop culling in 2025, everyone needs to be alert to a possible U-turn on getting rid of badger culling for good.

The Oxforshire Badger Coalition (OBC) is a growing network of people and organisations from Oxfordshire and beyond who are concerned about the continuing, and potentially accelerating government badger cull policy.  This is a policy that is based on the Randomised Badger Cull Trials (RBCT) and what Lord John Krebs described recently in the House of Lords as ‘unsettled science’.

Badger culling has been happening in Oxfordshire since 2020, firstly on the periphery as overspill from adjoining counties, then with a full cull area added each subsequent year. An estimated 50% or more of the county now has culling, with 5000 or more badgers shot so far, and plans for thousands more this year and next.

The situation for Oxfordshire’s badgers is moving to a point where there is a serious risk that culling is running out of control. The NFU has been setting up large ‘cluster area’ projects that may include future 100% culling, perhaps starting next year and even though bovine TB breakdowns have reduced greatly in recent years with better testing.

The risk is a change from the existing proactive policy, to a new reactive culling policy, a move that it is thought will be subject to consultation later this year. No culling, even in exceptional circumstances, is warranted. Reactive culling threatens to become the ‘new normal’, but it is not based on sound or impartial epidemiological evidence (1).  The result could be 15 more years of 100% localized badger culling, and another 200,000 or more largely healthy badgers killed.

This is justified in part by Minster (Spencer) claiming in Parliament that badger culling is working, with a 45% benefit after three years and 50% after four years, but these numbers have no peer-reviewed or even published basis, and appear to be misinformation. Alternative peer-reviewed analyses (2) show that badger culling has produced no benefit in disease reduction. Despite a lot of claims and accusations by government, this work has not been effectively challenged.

The Oxfordshire Badger Coalition is determined to raise the profile of these issues in Oxfordshire over the coming months, so you may be seeing more badgers in Oxford in the very near future. Please say hello, and if you can, join in and spread the word. Most members of the public who stopped to say hello this week were supportive and said that they were not aware that the government is still killing badgers. This is because both badger culling and the results are being being kept secret from the public from reasons that remain unclear.

Is APHA’s approach to bTB control negligent?

Posted on by

The annual bovine TB epidemiology reports (1) for England and Wales, both compiled at APHA Weybridge, have historically had authors in common. More recently however, the reports no longer publish the identity of the authors. Why might this be? What we see now is a definite disparity in approach, presentation and implication.

The emphasis on wildlife and Risk Pathways Analysis (RPA) in the England reports is noticeable, compared to the Welsh versions (Table 1) which barely mention them. So whilst bTB is clearly the same disease in both countries, the attribution to wildlife, cattle movements and residual infection differs very markedly as you cross Offa’s Dyke.

*Wales not yet reported

Table 1. Mentions of the risk pathways approach and badgers and wildlife as a source of  bovine TB infection in APHA reports for Wales and England 2016-2021. Note near absence of mention for Wales, while England has a growing obsession over wildlife involvement.  Will attempts be made to force Wales to follow England’s scientifically unreferenced pathway?

These differences have occurred due to the use in England of un-evidenced data to support a policy that culls badgers in England, whereas in Wales no such policy exists (2).  RPA was introduced in 2015 by APHA on a trial basis by vets using the newly updated Disease Report Form (DRF), and with the stated aim of identifying the source of bTB breakdowns, defined as ‘hazards’. In this trial, the pathway by which disease entered the bTB infected herd was to be decided by the investigating vet. The DRF provided a list of epidemiological hazard options to select; the option of attributing disease to wildlife was the default where attribution to a cattle source was not immediately obvious. The trial was quickly hailed as a success and expanded in 2016 with a few changes. In 2017 it was adopted by APHA as a standard recognised procedure for identifying the source of an infection, training vets to routinely misdiagnose.  

Risk Pathways; a process hijacked by pro-badger cull advocates

APHA have not been able to provide scientific citation to validate the use of RPA protocol. Despite claiming since 2019 that they have a supporting paper in preparation for peer review and publication in a scientific journal, over three years later this has not appeared. It could perhaps be argued that RPA has all the hallmarks of being constructed by APHA to facilitate and support widespread badger culling, because that in effect is what it has done.

Since 2017 RPA has become the primary tool to implicate badgers as the source of the majority of incidents in England (2,3). Wales, in contrast, cites cattle movements, residual cattle herd infection and poor cattle purchasing decisions as the primary sources of bTB herd infection.

A trawl through recent APHA English County bTB reports reveals a plethora of statements about badgers which are not supported by qualifying scientific evidence. Many of these are stated as if they are settled science (they are not), or with descriminatory language. Below are a few examples from the Executive Summary of the APHA England 2021 epidemiological report (4) :-

“Eradication of bovine TB requires control of infection in both cattle and the main wildlife reservoir (badgers).”

“In 2021, as in previous years, herds located in the HRA (where there is high infection pressure from cattle and badgers),…….”

“For England, the source of infection with the highest weighted contribution was badgers (49%), followed by ‘Other or Unknown’ sources (17%). The most frequently considered sources of infection in the HRA were badgers (52%) and ‘Other or Unknown’ sources (16%). In the Edge Area, badgers constituted 52% of the considered source, followed by cattle movements (17%).“

“The existence of local reservoirs of M. bovis shared by cattle, badgers and other species; wildlife reservoirs of M. bovis are more common in the HRA and the western and northern parts of the Edge Area.”

Compare this with the extracts from the Executive Summary Wales Bovine Tuberculosis Surveillance Report 2020 (5), where there is not a single ‘wildlife’ reference.

“The risk of a herd becoming infected with TB is associated with factors such as herd density, herd size, production type, TB history and location. These factors contribute to the spatial pattern of TB in cattle herds across Wales. Dairy herds had a significantly higher TB incidence rate compared to beef herds, with this effect remaining after adjusting for herd size and location. Similarly, herds with more than 300 animals have the highest incidence rates, with this effect remaining after adjusting for herd type and TB Area.”

“The increase in recurrent infection (a TB incident occurring within the last two years) in cattle suggests this remains an important driver of infection in Wales.”

“Use of antibody blood tests increased by 85% in 2020 compared to 2019, with 11-13% of tests disclosing reactors in the high TB areas, west and east, intermediate TB area mid Wales.”

From 2017 onwards, the England epidemiological report has a map illustrating the areas of England where badgers are considered by (what is described as) “informed veterinary opinion” to be the source of bTB infection. This is veterinary opinion that has been informed by APHA’s flawed briefing of vets.The map suggests that badger contribution far outweighs that of cattle. Combined with DRFs, from which the map data is derived, it offers no evidence to support this veterinary judgement. There is a clear bias towards blaming badgers. It even references “infected badgers” within the text, with an admission from APHA that no badgers have been clinically tested.

There have already been 10 years of intensive badger culling in England, and there appears to be some intention to continue with so-called ‘epidemiological culling’ into the future, despite a lack of evidence as to efficacy (6). APHA’s epidemiological assessments try to justify this new style epidemiological culling, by ‘finger pointing’  badgers as the source of breakdowns.

Unscientific perpetuation of wildlife involvement persists

The unscientific claims of wildlife involvement in bTB persist. They are being pedalled via epidemiology reports that lack scientific evidence and backed by vested industry and veterinary interests. The speculative blaming of badgers as a source of bTB infection in cattle, without scientific evidence or justification, seriously undermines the whole bovine TB eradication policy.

APHA pride themselves on being a world class science establishment, supported by such statements as :

“Science continues to be fundamental to everything APHA does and we are committed to high quality science-based evidence for decision making and policy development. We will deliver this strategy over the next five years.”

The new model for epi-culling is not quite the model of scientific rigour APHA aspire to. Is it more a clear case of confirmation bias, remoulding and manipulating information to support a government policy that has tried to normalise removing large numbers of healthy badgers from the English landscape, contrary to high quality science based evidence and to correct handling of uncertainty and precautionary principles.

It has to be asked, has this manipulation been intentional? Is incompetence or even negligence the right perspective? Will public opinion continue to be ignored? Who exactly is pushing biased procedures? What level of pressure is being exerted from vested interests, and who is routinely interfering with government science?

Long-term protection for badgers in Bas-Rhin, France

Posted on by

Monday, May 15 was World Badger Day, but in France protection depends on which side of a boundary the badgers are.

Photo L’Alsace /Marc WILB

Badgers are not all in the same boat in the Alsace region of France. There are the lucky ones, in the department of Bas-Rhin, where hunting is not allowed. Sadly, their neighbours, in the Haut-Rhin, can be hunted legally as in the rest of France.

The Bas-Rhin is therefore a national exception to the rule, the only department where it has neither the status of pest nor of  a huntable animal. “In fact, it is classified without legal status. This means that there is no authorization to hunt it and therefore that it cannot be hunted”, says Lætitia Duhil, badger referent at the League for the Protection of Birds.

The status of ‘pest’, hunted or not, is defined in each department by commissions bringing together hunters, farmers, foresters, environmental associations, and representatives of the State. In the Bas-Rhin, the associations advised at the end of 2004, a cessation of badger hunting.

Since then, it has not been deemed necessary to return to hunting, on the findings that a natural balance in their numbers now prevails and there is simply no need. In the Haut-Rhin, however, the wildlife commission has not yet invalidated badger hunting. Last year, only a hundred badgers were killed, an insignificant number compared with an estimated population of 10,000 – 15,000 badgers across Alsace. Leaving badgers alone seems to simply be the best way to manage them. This philosophy will hopefully now spread across France and elsewhere in Europe.

Bovine TB and Badgers: a weakened link

Posted on by

A new article in the May issue of British Wildlife magazine provides an overview of the current state of affairs with badger culling in England, and a welcome update on the science surrounding the issue.

It looks at new work that questions the role that badgers play in bovine TB in cattle, and what the most likely reasons behind the perpetuation of the disease are.

It also looks at the problems that badger culling is likely to be causing to the ecosystem in general, and whether or not this is being adequately monitored or mitigated.

There is a potted history of legal challenges to the badger cull, and a view on the insight and benefits that this difficult work has provided.

It looks at where the current government intends to take the badger culling policy next, and what ‘epidemiological culling’ could mean for our badgers in the future.

You can access a copy of the article here, for a charge of 99p.

Where are they killing badgers?

Posted on by

Below is a summary table of the number of badger cull zones in each county of England since 2013 and those predicted according to government indications until 2025 (end of January 2026).  A measure of culling intensity is the number of cull areas, although some counties such as Somerset are far larger than others. It’s a sickening reminder of how extensive the culls have been, with already over 210,00 mostly healthy badgers reported shot, and many thousands of adults and cubs injured by the cruel methods used. 

The ‘zones’ are the HRA (High Risk Area) the Edge (Edge Area) and the LRA (Low RIsk Area). Cumbria* and Lincolnshire* have been subject to localised culling of 100% of badgers. Some of the cull areas overlap with other cull areas, so this is a generalised picture.

Last night in the House of Lords

Posted on by

Last night (15th May) in the House of Lords, Amendment 47 of the Retained EU Law (Revocation and Reform) Bill was discussed. There were a couple of points raised which will be of interest to those following the science of badger culling.

The amendment, moved by The Earl of Caithness, was described thus:

47: Clause 17, page 20, line 34, at end insert—“(3) In subsection (1)(b), developments in scientific understanding must be identified based upon regular reviews of the scientific evidence.(4) When undertaking a review of scientific evidence referred to in subsection (3), the relevant national authority must consider the methodological quality of the evidence, in terms of the extent to which all aspects of a study’s design, data collection protocols and statistical analysis can be shown to protect against systematic bias, non-systematic bias, and inferential error.(5) Where regulations under subsection (1) constitute environmental law, the review of scientific evidence must also consider whether the evidence takes a sufficiently wide view of the ecological impacts.”Member’s explanatory statementThis amendment is to ensure that future regulations will be based on a proper assessment of the best science available.

Member’s explanatory statement:
This amendment is to ensure that future regulations will be based on a proper assessment of the best science available.

Lord Krebs was at last nights debate and said:

“I support in large part what he said about the importance of rigorous scientific evidence to underpin policy—he referred to the environment, but I would say more broadly. I will add a note of caution from my personal experience. As many noble Lords will know, I was responsible for instigating the randomised badger culling trials, the so-called “Krebs trials”, which were meant definitively to determine whether killing badgers was a good way of controlling bovine tuberculosis. The trial was probably the largest ecological experiment ever done in this country; it did produce results, but it did not settle the arguments or the policy. So science has an important role to play, and I support the noble Earl’s amendment, but we must recognise that political decisions come in as well.”

So Lord Krebs, who set up the Randomised Badger Culling Trials (RBCT), states that the results did not settle the argument as to whether killing badgers was a good way of controlling bTB in cattle.

Further, The Earl of Caithness, speaking in the same debate quoted Lord John Krebs from the recent debate on the Genetic Technology (Precision Breeding) Bill, where he said;

“scientists do not absolutely agree on everything”.

And;

“when there is a centre of gravity of opinion, there are always outliers. Sometimes those outliers turn out to be right and there are transformations”.—[Official Report, 25/1/23; cols. 221-23.]

So in summary: the RBCT did not settle the arguments on the efficacy of badger culling, and the outliers in scientific opinion sometimes turn out to be right and there are transformations.

Will this to be the case with badger cull science; the outliers will turn out to be right, and there will be transformations?

Independent Report Exposes Unsafe Procedures in Bovine TB Control in English Cattle

 

A new report on the possible future use of so called ‘epidemiological badger culling’ is being released to MPs and Parliament on 11th May 2023. Compiled over the last year by a group of independent experts, it looks closely at one specific element of the government’s bovine TB control policy proposals for English cattle herds; that regarding the role of badgers in bTB disease hotspots as they develop.

The report can be accessed HERE.

Government Policy in 2020 had suggested a move away from intensive mass badger culling, that by 2022 killed over 210,000 mostly healthy badgers in England since 2013. This huge programme of wildlife intervention has produced no demonstrable benefit to disease control in cattle, with the government silent on results since 2017.

Authored by experienced and independent researchers, veterinarians, and epidemiologists, it addresses DEFRA’s handling of the disease crisis, and why the 2020 “Next Steps” policy is likely to fail because of incorrect decision making and exaggerated claims made on the back of equivocal research results.

The report claims that the Animal and Plant Health Agency (APHA) and DEFRA, are failing in their duty to provide proper scientific approaches to vital aspects of the heavily publicly funded, long running bovineTB control crisis in England.

Specifically, it exposes the poor rationale behind aspects of the proposal which aims to implement systematic localized elimination in an area of all (100%) of badgers, an approach termed by DEFRA as ‘epidemiological badger culling’. This back-door approach to systematic removal of badgers from farmland where cattle have bTB, is already being trialed in a small number of counties and appears to be planned in more. But it is founded on evidence and beliefs that are not fit for purpose.

The 55 page report with 2 page summary, provides a catalogue of evidence on issues that the authors say have been consistently misrepresented by APHA and the Chief Veterinary Officer. It calls for an immediate rethink, scientifically robust planning and an end to supporting an ill-conceived policy with uncertain science and procedures.

The report is prepared in advance of an anticipated government consultation over its future policy to phase out badger culling.

The Canary sings: government adds multiple extensions to existing badger cull areas

Posted on by

Last Friday, The Canary online  published a story about how large scale badger culling continues to be extended, despite government claims in 2020 that it is being phased out. 

It reports on Freedom Of Information disclosures that show  Natural England approved 10 cull extensions in 2022 in addition to declaring new areas. This amounted to badger killing on an additional 327km2 of land. In 2021, it greenlit eight extension areas totalling 342km2 in all. Natural England  effectively confirmed that extensions are again likely for 2023 by indicating that these are “in course of completion”. 

It’s a deeply disappointing story of more and more healthy animals being mass killed  by stealth, just in case they are involved in the cattle TB epidemic and despite latest published peer- reviewed science showing badger culling has no effect on herd breakdowns. You can read the full article here.
