Cattle Farming

Cattle Liver Fluke and Welfare Impact

Liver fluke infestation causes significant welfare problems in cattle, particularly in wet UK conditions that favour the host snail.

Key Facts

Fasciolosis from Fasciola hepatica causes liver damage, anaemia, and reduced production
Acute fluke disease from massive early-stage fluke burden can cause sudden death
UK wet upland and lowland areas have high environmental challenge from fluke
Only triclabendazole is effective against all fluke stages including immature flukes
Resistance to triclabendazole is developing in UK fluke populations

Welfare Considerations

Liver fluke causes progressive welfare damage from subclinical reduction in production through to acute disease and death. Even subclinical infection causes chronic discomfort, reduced appetite, and immune suppression. Management combining targeted treatment with risk factor management - including drainage improvement and strategic grazing - provides welfare benefits alongside resistance management.

What You Can Do

Support cattle health planning including liver fluke risk assessment
Advocate for fluke monitoring and strategic treatment as welfare requirements
Choose beef from farms with documented parasite management programmes
