Data on tests, new incidents, restricted herds and cattle slaughtered with bovine TB for December 2023.

This report was revised on 10 May 2024, after initial publication on 20 March 2024. The revision was due to an error identified in the Defra TB Publication relating to New Herd incidents. This error was found to affect the December monthly values for each year from 2012 to 2023. Previously published figures for these months are correct and this issue only affected the latest release. Other related measures are unaffected. More information is available on Defra‚Äôs website.

As a result of the change new incidents for the year to December 2022 has been revised upwards from 592 to 601, and new incidents for the year to December 2023 has been revised downwards from 630 to 618. Changes have been marked with an (r).

The Department for Environment, Food and Rural Affairs (Defra) Statistics release, on which this statistical headline is based, includes statistics on the basis of the Wales TB areas.

Further information

The overall trend for animals slaughtered due to bovine TB control is variable. Much of the rise since 2014 is attributable to increased use of high-sensitivity testing. For example, gamma-testing, removal of Inconclusive Reactors (IRs) and severe interpretation of the skin test have all been used with the intention of clearing up infection and reducing the risk of the disease spreading and breakdowns recurring.

The monthly series is variable, and peaks can be expected from time to time. There had been an increase in the trend since the peak in October 2018 was reached, this has since fallen. Further analysis of this trend up to June 2019 has been published in the statistical article: Analysis on the number of animals slaughtered due to bovine TB controls, October 2018 to June 2019.
