CONFIRMED TB INCIDENCE IN "HIGH INCIDENCE" COUNTIES: 1997 AND 2006

  The headline TB herd statistic for Great Britain is TB incidence, defined as confirmed new incidents as a percentage of tests on unrestricted herds.

  This figure is reported in Defra's National Statistics on bovine TB, which includes a graph showing the incidence of TB since 1996. This graph is included as Annex B.

  The tables below provide a breakdown of TB herd incidence for the worst affected counties across GB in 1997 (ie pre-RBCT) and 2006 (post-RBCT).

  For the purpose of this document, "high incidence" counties include all those with a TB incidence equal to or higher than the national average for GB. Counties involved in the Randomised Badger Culling Trial (RBCT) are shown in italics.[4]
