Dawn, The only study I know of is on CJD crutsfeldt-Jacobs Disease (know to survive formalin fixation and routine processing protocols, the CDC web site has additional information, In my laboratories I put all blocks in hazardous waste for incineration disposal. It is not that costly just to be on the safe side.

Our pathologist for our private GI lab would like me to find out if anyone has done a study to determine if the paraffin blocks, once they have been processed, are considered biohazard. I have searched high and low and can find many people stating that the blocks are not bioharzard, with the exception of neurological tissue, but they don't state how they know this. He would like me to reference an actual study to prove that someone has actually looked into this. Any one know of something like this? I know common sense would say that once the tissues have been in formalin for hours, than on the processor for hours that the tissue would be non biohazard and completely safe. Thanks for your help :) -- Dawn R Bugge HT(ASCP), Lab Manager Seattle Histology Dawns Usborne Books Website <http://x3128.myubam.com/> _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
