Annex A
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]
