Active Surveillance

Surveillance Testing Programme

9. The measures which apply in the Edge Area are summarised below:

  • Surveillance:
    • increased test sensitivity by using six monthly or annual testing
    • 3km radial testing, around Officially Tuberculosis Free Status Withdrawn (OTFW) breakdowns in annual testing regions of the Edge Area
  • Management of new breakdowns to increased test sensitivity:
    • Officially Tuberculosis Free Status Suspended (OTFS) breakdowns to clear two short interval tests (SITs) at severe interpretation before restrictions can be lifted
    • Compulsory parallel g-IFN tests in OTFW breakdowns
  • Detailed epidemiological investigation and analysis
  • Preventative measures:
    • removal of Cattle Tracing System links between High Risk and Edge Areas
    • promotion of Risk Based Trading
    • badger vaccination and biosecurity
    • support for vet-farmer meetings and local boards
    • TB awareness events
    • information sharing - publicising six monthly reports locally
  • Periodic Reporting:
    • prepare and submit to TB Programme, six monthly epidemiological reports on progress
    • information sharing - publicising reports locally.

10. The Approach to Setting Routine TB Testing Intervals in 2018 Policy document (TR277) and Setting Routine TB Testing Intervals 2018 (TR283) provide more details.

Surveillance Strategy

1. Each country within GB administer a targeted surveillance strategy using agreed testing protocols appropriate to the prevailing disease situation.

2. A variety of different tuberculin test types are used to deploy the surveillance strategy on herds and individual animals. The tuberculin test types and VetNet codes table (TR15(E/S/W)) sets out:

  • all the possible types of tuberculin test
  • the corresponding Sam purpose/VetNet code
  • the reason and circumstances in which each purpose should be used
  • the classes of stock to be tested at each test type
  • whether zero tolerance applies
  • whether an automated Test Notification Letter (TNL) is generated.
