The Food Standards Agency (FSA) yesterday [Thursday] announced that 20 Beef Assurance Scheme (BAS) cattle have entered the human food chain without meeting the EU legal requirement of testing for BSE. An investigation is underway to establish how this happened, although the actual risk from these specific animals is negligible. There were no positive tests from the BAS animals slaughtered for human consumption in 2001, around 150 in total. There have been no clinical cases of BSE in bona fide BAS herds.
