[Histonet] The procedure that substitues xylene with mineral oil.

[Gayle Callis]

Phil and Renee,

If the solvents i.e. alcohols, xylene or xylene substitutes need to be 
collected for incineration after CJD cases, wouldn't mineral oil also need 
to be collected and disposed of in the same way?  The expense of collection 
will still be there no matter what the powers that be do not like to 
do.  Mineral oil may be less toxic compared to xylene but after 
contact.contamination with CJD or any other other prion diseased 
tissues,  it's status changes back to being a collectable solvent.

We work with prion diseased animal tissues using xylene substitutes (they 
work very well for processing and staining) and we are REQUIRED to collect 
these for incineration.
