News sites still write about the accuracy of the ban. By comparison, to lift the export ban on beef from the UK, the following stringent rules have to be followed...noticias.info /snippet -------------------------------------------------------------In the Roadmap, the Commission set out two minimum conditions that had to be met before any negotiations with the Member States on lifting the UK embargo could begin: * The incidence of BSE in the UK had to be below 200 cases per million adult animals per year. This was the level at which the OIE (World Organisation for Animal Health) defines a country to be of at “moderate risk” of BSE (the UK was previously classified as “high risk”). ------------------------------------------------------------- /end snippet. i.e. if 10 thousand cattle are tested for BSE less then 2 of them should test positive. A failure of this test would indicate a larger sample should be measured. A quick benchmark to establish sample size imo. and (regarding 100% testing of slaughtered cattle entering the human food chain) /snippet ------------------------------------------------------------As additional protection for consumers, stringent testing requirements for BSE are laid down under EU legislation. All animals above 30 months that are slaughtered for human consumption are tested for the presence of a misshaped prion protein called PrPres, which is regarded as a marker for the presence of BSE. The objectives of the BSE monitoring are not only to assess the BSE prevalence and evolution over time, which the impact of risk reducing measures to be evaluated and enables the review of other measures, but also to protect public health. Indeed the testing of animals prior to slaughter may detect animals presented for slaughter which may have unnoticed signs of BSE and also animals with the disease which are not yet showing signs. The identification and removal of these animals will be an additional protection for the consumer. The BSE post-mortem rapid tests operate by detecting PrPres in the central nervous system. Following slaughter, a sample of brain or spinal cord is taken from the animal using a special tool. This tissue is taken to the laboratory and tested for the presence of PrPres. Rapid tests are quick and reliable, and allow large numbers of samples to be tested. , -------------------------------------------------------------- /end snippet I am no authority on the statistics or issues involved, just a concerned citizen who has followed the BSE case in the UK.
