Abstract: At approximately 5:30 p.m. on May 8, 2011, Employee #1, a medical records clerk for Ccc Health Services, Richmond Health Center, died and tested positive for Legionella disease. He spent the majority of his day in the MRT records room on the first floor of the center. Approximately two hours of Employee #1's work day were spent at the public access window. Both of the aforementioned locations tested negative for legionella. However, throughout the day Employee #1 would also travel to other locations in the building to obtain medical records. County personnel took water samples from a total of twenty six separate locations to include: the cooling tower, possible drinking fountains used by Employee #1 and restroom facilities in the vicinity of Employee #1's prominent work locations. Test results indicated only trace levels of legionella, which were well below Federal OSHA Action Level Guidance. Water samples taken by the Division at four separate locations and analyzed by McCampbell Analytical resulted in nondetectable levels. These samples were taken at the cooling tower, the hot water taps of two separate restrooms in Employee #1's immediate work area, and the change room/shower room. The Contra Costa County Coroner was contacted to obtain the results of Employee #1's autopsy. The Deputy Coroner informed the Division that an autopsy was not requested for Employee #1. A copy of his Death Certificate was obtained from Contra Costa County Health Services and the cause of death was stated as: Acute Respiratory Distress Syndrome and Community-Acquired Pneumonia Legionella. Other significant conditions were listed as: Sarcoid Lung Disease and Chronic Immunosuppressive Therapy.
