LIVER FLUKEDisease caused by liver fluke (fasciolosis) is an increasingly common, economically important parasitic disease of cattle in the UK. The disease is caused by the parasite Fasciola hepatica.

Since around 2001, definite changes have been recorded in the regional prevalence, seasonality and severity of disease caused by fasciolosis infections of UK livestock, with particularly high prevalences following a series of wet years and concurrent spread from traditional fluke areas in western UK to normally drier and fluke-free eastern districts.

Chronic fasciolosis - Disease is caused by the presence of adult fluke in the bile ducts which feed on blood, leading to anaemia. Autumn-calving beef cows do not lactate well and have chronic diarrhoea with associated weight loss. In spring-calving beef cows, liver fluke exacerbates the metabolic demands of advanced pregnancy in cattle on marginal winter rations, resulting in the birth of weakly calves to cows with little milk.

Co-grazing sheep and cattle will greatly increase the risk of liver fluke in cattle because infected sheep release much higher numbers of fluke eggs.

Control programmes for liver fluke must take into account the farm history, geographical location and prevailing weather conditions local to the area. In areas with endemic fasciolosis, control relies heavily on strategic flukicide treatments.

Black disease – is typically associated with migration of immature liver flukes during late summer/early autumn and can affect unvaccinated cattle of all ages. Clinical signs are rarely observed and cattle are simply found dead.
