TB In Cattle In January

Defra released provisional data estimating incidence of TB in cattle for January 2010. The early results suggest that incidents for January 2010 are below those for January 2009 though care should be taken with the results until more tests are carried out because for example a high rate of unclassified incidents were included.

The provisional figures show that there was a 21% decrease of new TB incidents compared with last year. There was also a decrease in the number of herds tested over the same period giving an overall decrease of 15%. The provisional confirmed average indidence rate was 4% for January 2010 compared with 4.3% for January 2009. The confirmed average indidence rate is confirmed new TB incidents as a proportion of tests on unrestricted herds.

The number of tests on unrestricted herds was 6,069. There were 3,685 restricted herds and the total number of tests on herds was 7,410. There were 420 new herd incidents and 226-256 confirmed new incidents. The number of cattle tested in the 420 tests was 706,558 cattle. As a result of the tests 2,752 cattle were compulsorily slaughtered, 2,730 of which were reactors to the tuberculin test and 22 considered to have been in direct contact with TB infected cattle.
