Aside from the recent Rodent Pro issue http://www.in.gov/activecalendar/Eve...91&print=print which was addressed here http://www.faunaclassifieds.com/foru...d.php?t=334751 I am not aware of any other issues on that level.
I have heard recently that the main supplier of pet mice in GA had issues with their mice which is why mice have been pulled out from local ATL Petcos and Petsmarts (no idea on the issue itself) that's about it.
