When a breakdown begins with an animal positive at an individual animal test or a Lesion at Routine Slaughter (LRS) and a full herd test has not recently been completed, an RHT may be required.

Disease eradication programs consisting of post mortem meat inspection, intensive surveillance (including on-farm visits), systematic individual testing of cattle and removal of infected and in-contact animals as well as movement controls have been very successful in reducing or eliminating the disease.
