Provisional data for June 2010 shows that there from 3,778 tests on unrestricted herds (previously TB free) there were 385 animals which either reacted to a tuberculosis test or had tuberculosis disclosed by routine infection at slaughter.
Of these 385 animals, it is expected that between 146 and 218 will be confirmed with TB.
This figure is slightly higher than the June 2009 estimate, in which there are 365 new herd incidents, of which 182 were confirmed.
Overall, provisional statistics show a four per cent decrease in the number of new TB incidents in January - June 2010 compared to the same period in 2009. 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 9.9 per cent.
The provisional average confirmed incidence rate (confirmed new TB incidents, as a proportion of tests on unrestricted herds) was 3.8 per cent for January - June 2010, compared to 4.2 per cent for the same period in 2009.
