The percentage of TB incidences has shot into double digits in one county for the first time this year, according to the latest figures from the Department of Agriculture, Food and the Marine.

According to department statistics for the second quarter of 2017, a total of 6,752 animals tested positive for TB so far this year. This is up marginally on figures from the same period in 2016, when 6,693 reactors were found – a rise of 59 cattle.

The national herd incidence for 2017 so far is 2.81% – up slightly on the figure  of 2.77% from the end of June last year.

In terms of TB ‘blackspots’, once again, the east of the country has been hit hardest, with Wicklow West, Wicklow East and Dublin being worst affected.

Meanwhile, Waterford, Longford and Roscommon were the counties least affected by TB in the last six months.
