The latest parasite forecast from the National Animal Disease Information Service (NADIS) has predicted high prevalence of both liver fluke and lungworm in cattle as autumn continues.

The National Animal Disease Information Service (NADIS) has announced that the high risk of liver fluke in Scotland, Wales and western England will continue throughout autumn 2012.

The risk of liver fluke in Wales, Scotland and western Scotland remains NADIS made the announcement in its latest monthly parasite forecast.

On control, NADIS recommends treatment – involving the use of triclabendazole – for those sheep farms with a known liver problem who have not already treated the animals. Sheep farms with no previous evidence of fluke disease are recommended to monitor for the presence of infection via post mortem examination of all sudden deaths.

The service also recommends that cattle which have been exposed to liver fluke infection at grass should be dosed at housing. Out-wintered cattle also exposed to high levels of fluke should be treated with a flukicide in late autumn.

The November parasite forecast also warns that the wet summer seen in some parts of the country had also resulted in a high prevalence of lungworm disease in cattle.

However, NADIS calls the prevalence of lungworm in the UK “unpredictable” and suggests that all vets, farmers and animal health workers should be aware that “all ages” of animal remain susceptible to the disease.

The service believes vaccination of youngstock should be considered on farms with a history of the infection and this allows for “the development of immunity before exposure to risk”.
