Finding a Heiferlump and curing bovine Tuberculosis

In April 2017, Brian May – the rock star turned badger conservationist – brought together policy makers, scientists, veterinarians and farmers to discuss the continuing problem of bovine tuberculosis (bTB) in badgers and cattle. Whilst most media attention has focused on the controversy of badger culling, my recent paper in Transations of the the Institute of British Geographers, “Navigating veterinary borderlands: ‘heiferlumps’, epidemiological boundaries and the control of animal disease in New Zealand” (Enticott, 2017), examines a fundamental question: how do we even know what bovine tuberculosis is? And, is it the same everywhere, or do we need different ways of seeing disease to meet different local contexts?

Knowing Bovine Tuberculosis

Confronted with disease, most people want to be certain that a disease is present or not – that somehow disease can be routinely and easily diagnosed, and that this diagnosis would be the same anywhere. Such a belief in the universality of disease is popular amongst policy makers and epidemiologists too: it provides the basis for standardised responses to disease throughout an area or country. As my paper shows, though, in the field or on the farm, these universalities can be far from helpful. Rather, than relying on universal perspectives, the paper shows how accepting the mutability of disease by combining different knowledges and understandings can be central to its management.

Heiferlumps and Striking Farmers

The argument made in the paper comes from an historical analysis of attempts to eradicate bTB from New Zealand. Records of meetings held by the Department of Agriculture in New Zealand National Archives show that as the eradication programme was rolled out in the 1960s, the effects upon farmers’ businesses began to be felt, leading many to question the accuracy of the diagnostic tests. The problem was felt most on the West Coast of New Zealand. Farmers here refused to test: their strike causing political consternation. Local vets, too, had their doubts about the accuracy of the test. The problem seemed to be what was known locally as ‘Heiferlumps’ – young cattle testing positive to the skin test used to diagnose bTB, but which had no internal signs of disease at slaughter. One of these vets, Peter Malone, led pleas for a ‘lighter’ interpretation of the test results – what he called ‘reading light’ – but was ignored by senior government vets in the capital, Wellington.

The relationship between vets and farmers on the West Coast and government officials in Wellington turned toxic when Malone admitted to ignoring heiferlumps when interpreting the results of bTB tests. The Department of Agriculture’s leading vet, a Scotsman called Sam Jamieson responsible for the eradication program, and known for his short temper and scientific approach, was outraged. Malone was forbidden from testing, only stoking an air of mutual mistrust between vets and farmers on the West Coast and distant government vets like Jamieson.

In the ensuing controversy, Jamieson turned to a field trial to establish the veracity of the bTB tests and rule out the possibility that there could be local variations in the nature of bTB. It had little effect: although the trial proved the test was good, no test is ever 100% accurate and farmers and vets continued to raise doubts. But rather than more science, what came to settle the dispute was a new kind of science: a version of epidemiology that was not confined to a particular discipline but crossed boundaries to combine different ways of knowing disease .

The paper refers to this new approach as ‘borderland epidemiology’ in which
government vets came to recognize during the 1970’s that bTB was as much a social and moral problem as an epidemiological one. Archive documents show that they began to dispense with the rule-book, and instead working with farmers, to modify and adapt how bTB should be diagnosed, and reflect unique geographical variations. Understanding that managing disease is a balancing act made from negotiations rather than universalisms has since become a principle on which New Zealand has been able to almost eradicate bTB

Lessons for the UK?

Could these experiences from New Zealand be relevant to the management of bTB in the UK? On the one hand, Defra – the government department responsible for managing bTB – look favourably upon the New Zealand approach to managing disease, their recent strategy mentioning them more than any other country (Defra, 2014). Yet, at the same time, there appears to be little room for manouvre to experiment and try new approaches to managing disease. In fact, as revealed at Brian May’s summit, attempts of the kind conducted in the 1970s in New Zealand, but by vets in England, have been ruled illegal and halted, despite their positive impacts upon disease and farmer engagement with disease management process.  In future, however, as my paper argues, adapting and adjusting diagnostics to local geographical variations by working with farmers to develop new kinds of veterinary knowledge may offer the best chance of dealing with disease.

People Power; Shaping England’s Nature

By Paulette Cully

With the aim of being the greenest Government ever, the present incumbents have made the delivery of a Natural Environment White Paper a top priority, which they hope to publish in spring 2011. In preparation for this the Department for the Environment and Rural Affairs (DEFRA) published the “Shaping England’s Nature” discussion document in July this year.  Its aims are to encourage debate over how we can best protect and improve our natural environment. The article highlights our multifaceted regard of the environment. On the one hand the environment has great personal importance to individuals who enjoy it thorough it’s “green spaces, countryside, wildlife, rivers and seas” and “the quality of life in all of our communities”; whilst on the other hand the natural environment “underpins our economic prosperity, our food security, our health, our ability to adapt to a changing climate and to reduce the greenhouse gases which cause this change”. However, in the past the two sides have been in conflict, rather than being mutually inter-reliant  they have been regarded as competing choices. The consultation document gives us the opportunity to be the generation which puts this right, so that rather than limiting damage to the environment we can enhance it. DEFRA points out, that a vibrant natural environment is necessary for economic recovery and sustainable growth.

For a valuable insight into present day environmental policy making, its’ regional variations and the value of people power, Kate Muir et al have written a fascinating article in Area, “Shades of green in local authority policy-making: a regional case study”.  The authors show that there are clear intra-regional environmental policy dissimilarities in both level and form.  The paper also suggests that in part these differences may stem from the presence of environmental policy “champions” in positions of power and influence and environmental pressure groups who are able to communicate environmental agendas to local policy makers; thus demonstrating the importance of our say in environmental matters.

With that in mind, download the DEFRA consultation document to read their proposals; now is the time to have your say in the future of our environment.
