Work with transgenic mice which lack normal prion and apparently can't be 
infected by brain grafts from normal, infected mice strongly suggests the 
problem is not organo-pesticides but is prion related.  Given the widespread 
use of organo-pesticides on all sorts of crops, if that were the link to CJD 
I'd expect lots more cases...
