10. BSE National Surveillance Plan GOAL: Obtain as many samples as possible from the targeted high-risk population in a 12-18 month period

11. BSE Surveillance Plan Targeting population where disease is most likely to be diagnosed – most efficient Targeting population where disease is most likely to be diagnosed – most efficient Assumption if we cannot find disease in targeted – or most likely – population, even more unlikely to be found in non-targeted population Assumption if we cannot find disease in targeted – or most likely – population, even more unlikely to be found in non-targeted population Use data obtained to extrapolate information about broader cattle population Use data obtained to extrapolate information about broader cattle population

12. BSE – Targeted Surveillance Non-ambulatory animals Dead stock Field CNS Cases and on-farm suspects Veterinary Diagnostic Laboratory data Public health laboratories Ante-mortem condemns at slaughter
