Bovine Tuberculosis

Lord Trees Excerpts

Tuesday 12th December 2023 Lords Chamber

[Lord Harlech (Con)]

The noble Lord is absolutely right on the 56% reduction in incidence in cattle; that was one of the statistics I had prepared for the Dispatch Box. With our culling strategy, we will continue to follow the science. Culling will remain part of our toolkit for tackling this insidious disease for as long as necessary. However, we are moving to the next phase of our long- term strategy, which will also focus on wider-scale badger vaccination as the primary TB control measure in badgers.

[Lord Trees (CB)]

My Lords, a cattle vaccine will be a very valuable tool in controlling bovine tuberculosis, but it is likely to be several years before it is rolled out. In the hotspots of TB in the south-west of England, there is mounting evidence that outbreaks and breakdowns in herds are being linked to the continuing presence of infected cattle in those herds that are not detected by the current statutory tests. Will His Majesty’s Government urgently support the introduction, as a mandatory requirement, of additional diagnostic tests, which exist and are well proven, to aid the detection of such carrier cattle and their removal from herds? That would expediate the eradication of this terrible disease.

[Lord Harlech (Con)]

My Lords, I defer to the far greater knowledge and experience of the noble Lord, Lord Trees, in this area than my own. No diagnostic test for TB or other diseases is 100% accurate. The causes of recurrent cattle TB breakdowns in areas of endemic bovine tuberculosis are complex and manifold. The skin test is useful as a primary screening test and is supplemented by approved, ancillary tests where needed, based on stringent risk assessments. Defra supports the development of new diagnostic tests for TB and encourages test providers to seek World Organisation for Animal Health validation for UK regulatory approval.
