I think you have effectively put yourself out of the frozen section
business in fact, histopathology laboratory business. 

I agree with another comment, risks are still there even with paraffin.
How about those bloody tissues not completely fixed, infectious agents are
still viable (other than CJD) which 'lives' on to 'bug' you forever.  

There are ways to safely work with frozens, hence all the discussion a
couple of weeks ago on ways to disinfect a cryostat.   I suggest you
rethink your policy.
