RE: [Histonet] Are Paraffin Blocks Biohazard

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.

Subject: [Histonet] Are Paraffin Blocks Biohazard

Hello Histo World!

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 :)

Tell your pathologist to relax, nobody in the lab will sue him (or her) for any 
disease gotten from a paraffin block OTHER than a prion case.
As far as I know nobody has wasted time and money in proving this issue but you 
can have "a hint" when the "ultra cautious" CAP has not classify them as 
"infectious".

I think it may be on the OSHA website under the bloodborne pathogen standard - 
fixed tissue is considered non-infectious and non-hazardous.  Below is what 
OSHA considers potentially infectious materials and specifically addressed 
unfixed tissue, fixed tissue would therefore be considered non-infectious.

occupational exposure to blood or other potentially infectious materials (OPIM) 
place workers at risk for infection with bloodborne pathogens. OSHA defines 
blood to mean human blood, human blood components, and products made from human 
blood. Other potentially infectious materials (OPIM) means: (1) The following 
human body fluids: semen, vaginal secretions, cerebrospinal fluid, synovial 
fluid, pleural fluid, pericardial fluid, peritoneal fluid, amniotic fluid, 
saliva in dental procedures, any body fluid that is visibly contaminated with 
blood, and all body fluids in situations where it is difficult or impossible to 
differentiate between body fluids; (2) Any unfixed tissue or organ (other than 
intact skin) from a human (living or dead); and (3) HIV-containing cell or 
tissue cultures, organ cultures, and HIV- or HBV-containing culture medium or 
other solutions; and blood, organs, or other tissues from experimental animals 
infected with HIV or HBV. The following references aid in recognizing workplace 
hazards associated with bloodborne pathogens.

Take a look at this document. It should help you.
IATA and DOT have plenty of documents and training that you can take to 
understand this better.
