Five herds have reportedly tested positive for the infection in recent months – four in the area surrounded by the M6 and A65 and to the south of the new auction mart at Junction 36 of the M6. Another herd tested positive in area around Flookburgh, near Grange over Sands, south Cumbria.
Ahvla said there was generally five to 10 TB outbreaks in Cumbria every year.
The last major outbreak in Cumbria was near Penrith, in April 2011, when 103 infected cattle were destroyed.
Gonzalo Sanchez, Ahvla veterinary lead for the north of England, said: “Cumbria and Lancashire remain low risk areas of bovine TB, however there are a small number of TB breakdowns each year, typically as a result of bought-in infection from TB high risk counties.
“To put this into perspective, in 2012 there were five OTFW (Officially Tuberculosis Free Status Withdrawn ) in Cumbria out of 3,500 registered cattle herds, which is a very small percentage.
“So far there is no evidence of bovine TB infection in wildlife in either Cumbria or in Lancashire.”
