Perhaps more seriously, the article suggests that the calculations "destroy for ever" the assertion that BSE "posed no threat to human health". Mathematical calculations do not constitute evidence for or against a causative link between BSE and CJD.
The work on examining possible future scenarios is continuing and it is disappointing that comments should be made about work that is not yet complete, let alone published.
