Farmed Cattle Liver Fluke Welfare and Control

Liver fluke (Fasciola hepatica) is a significant welfare and production problem in cattle across wet grazing regions.

Key Facts

Liver fluke affects an estimated 30% of UK cattle herds in high-risk areas
Acute fluke causes liver haemorrhage and sudden death, particularly in young stock
Chronic fluke causes weight loss, anaemia, ill-thrift and reduced milk yield over months
Resistance to the main flukicide (triclabendazole) is emerging in several UK regions
Strategic use of flukicidal treatments and pasture management reduces population buildup

Welfare Considerations

Liver fluke causes significant suffering - acute disease involves liver destruction with rapid death; chronic disease involves prolonged ill-thrift, anaemia and immune compromise. Strategic control using faecal egg counts and strategic treatment timing reduces welfare harm while minimising drug resistance development.

What You Can Do

Support farms with strategic fluke monitoring and treatment programmes
Advocate for veterinary guidance on fluke control as standard in cattle health plans
Support research into flukicide resistance and alternative control strategies
Ask beef and dairy producers about their fluke control approach in high-risk areas
