"can"  Whenever one of these cases hits the news, I have noticed that it is always a butter huffer.  It could just be the odds, since most of society is butter huffers, but I would like to see some science on how MRSA takes hold externally.  I remember reading something about acetaminophen sets the stage for it to take hold, and we know almost all fats have to take meds for "muh knees muh back".
