BSE ('Mad Cow Disease') & British Beef Safety (1988–1996)
Document A, case 03
- Original advice
- For nearly a decade, UK ministers assured Parliament and consumers that British beef was completely safe to eat and posed no risk of transmitting Bovine Spongiform Encephalopathy (BSE) to humans.
- How it was framed
- Ministers repeatedly cited the 1989 Southwood Working Party and the Spongiform Encephalopathy Advisory Committee (SEAC). In 1999 written testimony to the BSE Inquiry, former PM Margaret Thatcher stated her government was 'almost completely dependent on the scientists' and could not 'second guess the experts'.
- Later change
- On 20 March 1996, Health Secretary Stephen Dorrell told the House of Commons (Hansard) that new SEAC findings identified a probable link between BSE and fatal variant Creutzfeldt-Jakob Disease (vCJD) in humans.
