Health authorities announced on Friday that the first known case of variant Creutzfeldt Jakob disease (vCJD) in the US has been discovered in Florida, but officials are insisting that there is no cause for concern amongst US consumers. The Florida Department of Health (FDH) says that the 22-year-old British woman who has contracted the illness, the human form of mad cow disease, is likely to have done so by eating BSE-contaminated beef in Britain during the 1980s or 1990s before BSE controls were brought in. The department is investigating the case with the Atlanta-based Centers for Disease Control and Prevention (CDCP).
