Staph and Mersa are bad, I know they said it was safe, but it spreads through air, touch etc. and is very dangferous, even deadly a lot of times. They call it the super bug because it's resistance to anti bacterials and ability to spread. Unless the staph is treated properly the first time, the bug will groqw immune to the meds, and new meds are needed, until you run out of meds. It is very common on door knobs public places etc.
