Hi THE,
There are numerous discussions about this on the General Discussion Board here at TER.  You can also read up on the subject at CDC and/or give the Red Door clinic downtown a discreet call.

Yes, you can pick up things from DATY.  I haven't met anyone who has and I think the risks are quite low, but I'm not an expert.  Some use a dental dam (saran wrap), maybe that would be an option?

Have fun
