FWIW--this did NOT happen at a HOSPITAL pharmacy. This was an outside IV company that was at fault. It actually effected patients in several Birmingham hospitals; not just one. Thank God, my hospital does not use that company.
Local reports say the bacteria was found in several places in the prep area AND that sterilization should have killed the bacteria but did not. I'm not sure this was a particular pharmacist/pharmacist tech error; sounds like a system error.
As a side note of interest...the owner shut up shop the day the story broke and is said to have left town. That has guilt written all over it imo.
