Cattle Liver Fluke Welfare Impact

Liver fluke (Fasciola hepatica) causes significant production losses and welfare impacts in cattle across wet, low-lying farming regions.

Key Facts

Acute fasciolosis causes sudden death from liver haemorrhage in heavily infected cattle
Chronic fasciolosis causes weight loss, bottle jaw, and anaemia over months
Fluke risk correlates with wet weather and mud snail habitat on farm
Strategic treatment timing based on regional risk forecasts improves efficacy
Flukicide resistance is emerging, limiting treatment options

Welfare Considerations

Liver fluke causes prolonged suffering in chronically affected cattle. Weight loss, anaemia, and reduced appetite compound over months without treatment. Welfare-conscious management combines strategic treatment, drainage improvement to reduce snail habitat, and monitoring of treatment efficacy to detect resistance.

What You Can Do

Support farms using liver fluke risk forecasts for strategic treatment timing
Advocate for flukicide stewardship to preserve treatment efficacy
Choose beef from farms with integrated parasite management programmes
