Bovine TB: The Independent Scientific Group on Cattle TB

The Independent Scientific Group on Cattle TB (ISG) is a group of independent scientists who advise the Secretary of State for Environment, Food and Rural Affairs on how best to tackle the problem of cattle TB.

For ease of administration, this ISG section of the Defra website is organised by Defra officials, but this in no way alters the validity of the preceding statement on the independence of the ISG, who are solely responsible for its content.

In their own words:

'The Independent Scientific Group on cattle TB was set up following the acceptance by Ministers of the recommendations contained in the Krebs Report (1997). From this it was clear that the problem of TB in cattle was extremely complex, still poorly understood and that previous policies to control the disease had been inadequate. It recognised that substantial further work was necessary if an informative framework was to be established that would be adequate to underpin an effective policy to control the disease in the future.

'The role of the ISG is to provide the scientific base for such a policy. From the outset we have adopted a holistic approach, recognising that sustainable control policies could only be achieved through a better understanding of the epidemiology of TB in cattle and wildlife reservoirs. Implicit in our approach is the recognition that the widespread elimination of badgers from large tracts of the countryside would not be politically or socially acceptable, hence we have sought to explore a much wider consideration of the problem and its possible solution(s)'

A letter dated 5 September 2005 Adobe acrobat pdf file (240 KB) from the ISG responding to the Parliamentary Under Secretary's request Adobe acrobat pdf file (334 KB) for the release of data from the RBCT. Letters dated 29 September 2005 from the ISG to the Parliamentary Under Secretary Adobe acrobat pdf file (13 KB) and the Chief Scientific Adviser Adobe acrobat pdf file (12 KB) about the ISG's September 2005 interim analysis of proactive and survey-only data from the RBCT. The ISG's accompanying report Adobe acrobat pdf file (118 KB) and a report Adobe acrobat pdf file (39 KB) on the analyses prepared by the RBCT independent statistical auditor are also available.

Note: The figures in the ISG and statistical auditors' reports accompanying these letters differ very slightly from those now published in Nature, as a consequence of further data checking and analyses undertaken by the ISG since 29 September 2005.
