RE: [Histonet] Paraffin blocks - Dangerous goods?

From:"John Mackinnon"

I would say that that regulation would be open to interpretation.  My
interpretation would be that most tissues following fixation do not
contain viable pathogens and in most cases it would be reasonable to
expect that it does not contain pathogens and is therefore not a
biohazard.  I know that there are some infectious agents that survive
fixation and processing but in most cases we are aware of these because
they have been diagnosed (most of the time).  These few cases fit the
definition and should be handled accordingly.  This is just one mans

I wonder if all of the meat packing plants include a shipper's
declaration (E.coli, BSE) with their raw unfixed carcases they ship to
the grocery stores and butcher shops.  Now there is something to think

They are a regulated class 6.2, it is a substance known or reasonalbly
expected to contain pathogens.  If you ship dangerous goods you will
need a shipper's declaration which is required.

Would you further define or point me towards a regulatory definition
"Dangerous Goods".
Thanks, Greg

I have just been told that paraffin tissue blocks are considered
"Dangerous Goods" and can only be packaged and shipped by individuals
who have received special training.  Would anyone like to comment on
this?  Thank you.
