Liver fluke in sheep - a growing threat

Liver fluke, or Fasciola hepatica, is a flatworm parasite that infects the livers of cattle and sheep as well as other grazing animals such as deer. Fasciolosis is the disease caused by liver fluke infestation and has a serious financial impact on livestock production: it is estimated that each case of liver fluke costs the farmer £25-£30 (€34-€42) per sheep1 and £6 per lamb1. Farmers can lose:

Liver fluke can increasingly be found throughout the UK, due to favourable weather conditions such as warmer temperatures and increased rainfall in autumn and winter, and due to both infected animals moving around the country and infected snails moving through flooded areas. The level of risk to animals is entirely dependent on the number of infectious cysts present on pasture when animals are grazing, which is dependent on how the weather impacts on mud snail habitats and life cycle.
