On Nov 26, ten years to the day since the first reported case of bovine spongiform encephalopathy (BSE), veterinary experts at a press conference held to discuss the epidemiology of BSE and scrapie found that the audience were more interested in reactions to the latest media hype on new variant Creutzfeldt-Jakob disease (nvCJD). According to a report in The Independent (Nov 26) "hundreds of Britons will die every year from CJD caused by eating BSE-infected food".Commenting on the newspaper report, Prof Roy Anderson (Oxford, UK) said that he personally felt that to extrapolate from 14 recorded cases of nvCJD when so little was known about disease parameters was difficult and could not be done scientifically at present. Prof Ian McConnell (Cambridge, UK) agreed but added that he had not seen the data behind the newspaper report .
Returning to veterinary matters, Anderson reported encouraging results about how soon BSE would be cleared from the British herd. His latest estimates are that, if the older animals are culled first, the epidemic may be effectively over by mid-1998, rather than by 2001 as reported in August (Nature 1996; 382: 77988) and that only 150 cattle below the age of 30 months are currently infected.
Among the issues discussed was the possibility of clearing scrapie from sheep flocks. The scientists stressed that this should be a high priority because of animal health issues rather than human health considerations.
