Here's one for all you Regs buffs.

Are there any regulations that state that you cannot use a piece of
equipment for both human and research animals tissues?
The point in question, particularly, is the cryostat (although I'd be
interested in other histology equipment also).

One of our clinicians is ranting and raving about us using our CM3000 to
cut both human biopsies and animal tissues; not at the same time! This
is despite the fact that we have been doing this practice for the last
six years, and she knows this, and checked up with several pathologists
and agencies before hand. But now she knows better!
We always clean the cryostat and change the blade between tissues
anyway, whether it be different biopsies, or animal.
Thanks for any input.
