Gentlemen,
Thank you for the responses. I feel silly that I didn't google the fact that mice are not carriers, but I knew those little buggers carried rabies. I am plenty happy to be wrong in public and look a little foolish. Hanta is exceedingly rare in WI (freshly researched), so that's not much of a concern.
As for not using the 10mm, I did the pliers thing because I've had escapes when trying to move rodents that were not well glued down. But next time I'll use a 12 gauge or 416 Rigby to make up for this situation.
