BSE: Lessons from the Bovine Spongiform Encephalopathy Crisis
The BSE crisis of the 1980s-90s caused enormous cattle welfare suffering and transformed animal welfare, food safety, and agricultural policy worldwide.
Key Facts
- BSE affected over 180,000 cattle in the UK alone with fatal outcomes
- Affected cattle experience progressive neurological deterioration over months
- The epidemic resulted from feeding cattle meat and bone meal containing prion-infected material
- Variant CJD in humans increased political pressure for animal welfare reform
- Feed bans, surveillance, and slaughter policies effectively eliminated BSE
Welfare Considerations
The BSE crisis caused immense welfare suffering through the progressive neurological deterioration experienced by affected cattle. Signs including progressive ataxia, behavioral changes, hyperesthesia, and eventual recumbency represented significant welfare compromise over weeks to months of deterioration. The scale of the epidemic — hundreds of thousands of affected animals — created unprecedented welfare emergencies across UK cattle farming. The lessons from BSE transformed how animal feed safety, welfare monitoring, and disease surveillance are conducted, resulting in systems that protect future cattle welfare by preventing similar crises.
What You Can Do
- Support robust animal disease surveillance systems through policy advocacy
- Learn about the history of BSE as a case study in agricultural welfare failures
- Advocate for feed safety regulations that prevent similar crises
- Support transparent food supply chain monitoring for animal welfare indicators
- Engage with agricultural policy processes that shape future disease prevention
