Source: Bovine tuberculosis in England in 2021: Epidemiological analysis of the 2021 data and historical trends. Such movements are estimated to account for between a quarter and a fifth of all new TB herd breakdowns in the LRA each year and 1 in 6 in the Edge Area. In particular, movements of cattle from high bovine TB incidence areas of GB pose a substantial risk of introducing the infection to the lower incidence areas of England and Wales and to Scotland, which has been officially free of TB since September 2009. The movement of cattle with undetected TB infection is believed to be one of the most common ways in which this disease spreads to new areas. The different TB movement testing regimes in England, Scotland and Wales reflect regional variations in disease incidence, including the Officially TB Free status of Scotland. Introduction to Pre- and Post- Movement TB Testing This marks the first quarter since the second quarter of 2021 where no post-movement reactors were identified in any GB country.ġ.This was the fewest tests conducted in a single quarter since the policy’s rollout in 2018. Post-movement testing in the low TB area of Wales led to identification of no reactors, out of 1,578 tests completed.There were 224 post-movement tests in Scotland of animals that had arrived from annual and six-monthly testing areas in England and Wales.Post-movement testing in the Low Risk Area (LRA) of England identified no reactors, out of 11,086 tests completed.Pre-movement testing in Wales led to the identification of 28 reactors, including 6 IRs that became reactors at retest, out of 36,392 tests completed.This was the fewest such tests conducted in a single quarter since the first quarter of 2013. Pre-movement tests in England led to the identification of 34 reactors, including 1 inconclusive reactor (IR) that became a reactor at retest, out of 95,454 tests completed.Unlike the majority of TB tests, the pre- and post-movement tests reported on in this notice were arranged and paid for by herd owners. This notice contains statistics on statutory pre- and post- movement TB testing that is carried out to reduce the risk of spreading TB through movements of infected cattle.
