Cattle herds in Great Britain are routinely tested for TB. The frequency of surveillance testing differs between England, Wales and Scotland, depending on the level of disease.
In England, cattle herds in the Low Risk Area (LRA) are routinely tested every four years.
Cattle herds in the High Risk Area (HRA) are subject to annual surveillance testing.
In the Edge Area, cattle herds in higher incidence parts are routinely tested every six-months. Herds in lower incidence parts are tested annually, supplemented by radial testing around TB breakdowns with lesion and/or culture positive animals.
In Wales, all cattle herds are subject to annual surveillance testing, except for herds in the Intensive Action Area (IAA) where six-monthly testing is in place.
Although Scotland is officially TB free, cattle herds are subject to risk based surveillance testing. Cattle herds eligible for surveillance testing are tested every four years.
