Secondly, if cattle are to graze on-farm the following year, effective flukicide
treatment over winter will ensure that the cattle are not shedding fluke eggs in their dung onto pasture after turnout and will not contaminate pastures," said Dr Forbes.

The challenge from high levels of liver fluke on pasture continued throughout the first two months of 2013, and many farmers seem unaware that if sheep are put back on high risk pastures they will need to be re-treated with a flukicide
five to six weeks later to avoid losses.
She advised farmers to monitor flocks for signs of the disease and treat with an appropriate flukicide
Dr Vickers said: "Cattle rarely show signs of acute fluke disease, therefore unless acute disease is suspected or diagnosed, a flukicide
with activity against late immature/adult fluke stages (closantel, clorsulon, nitroxynil) may be selected, especially for treatments given in the late autumn/winter months.
Unless acute disease is suspected or diagnosed in cattle, a flukicide
that acts against late immature and adult fluke stages should be selected, such as closantel, clorsulon or nitroxynil, for treatment in the autumn and winter months.
NADIS said that stock should be dosed with a flukicide
around eight to 12 weeks after turnout to reduce the release of eggs from cattle infected already.
