Responding to the message of 
from "Cheasty, Sandra" :

We DO initiate an incident report when this happens. Unfortunately, many of our 
cases come from outside our institution and the possibility of CJD is not always
recognized by the sender or evident in the report.  We have had two cases come 
through just this year where CJD was not suspected, but they turned up positive.
For known or suspected cases, we have a specific protocol set up. All samples 
are processed by hand and cut under a hood set up specifically for CJD and other
prion diseases, using double gloves, gowns, goggles and so forth.  All tools, 
containers, etc,. used for processing, embedding, cutting and staining are 
disposable. Blocks and slides on positive cases are filed separately from all 
other blocks and slides in a closed contaioner. 
While it is indeed unfortunate (and a real pain) when this happens.....there 
WILL be times when a case "slips" through.
