DEFRA tested over 394,000 cattle for bovine spongiform encephalopathy (BSE) in Great Britain in 2007, including all suspected BSE cases, all fallen stock aged over-24-months and all healthy slaughtered cattle aged over-30-months. This testing identified 53 BSE cases, at a cost of over £55 million. DEFRA has produced a report on BSE surveillance for the Food Standards Agency. The report will be published on the DEFRA website.
