I have never been to any facility that left used syringes lying around. Let alone, uncapped needles. Please explain why you brought it home and cleaned it. Something does not sound right about this.
that is the point - funny girl. ;)
PS Most syringes are hollow that is the point.
Yes there is. You cannot clean a needle with hot water you know that wont' kill anything. I'm not sure why you brought it home with you and put yourself in the way of more exposure.
