Incidence of TB in UK Cattle - July 2009

However, care needs to be taken not to read too much into a single month's figure, especially as this figure includes a high number of unclassified incidents. As such the incidence rates are subject to further revisions as more tests and their results are input.

Provisional statistics show a significant change in the number of new TB incidents in January - April 2009 which were just 1 higher at 1969 compared to the same period in 2008. Combined with an increase in the number of herds tested over the same period, this equates to a provisional overall decrease in the TB incidence rate (new TB incidents, as a proportion of tests on unrestricted herds) of 5.3 per cent.

The provisional average confirmed incidence rate (confirmed new TB incidents, as a proportion of tests on unrestricted herds) was 4.1 per cent for January - April 2009, compared to 4.9 per cent for the same period in 2008.
