One of those articles indicates that the syringes were "dirty" (as in dusty and had obviously been stored near rodents), but they were not *used* (the distinction here is only made because I would expect that if someone was stupid enough to bring in a box of dusty syringes from home, they would likely give it a little rub on their lab coat so as to be unnoticeable). The other article doesn't make sense - the standard practice is to use one needle when drawing up more than one dose from a vial. Then it goes on to say that the vial was a single-dose vial and seemed to imply that the needle had been used in the patient and THEN put in the vial (again, no logic here). Seems like shoddy reporting to me.
