Legionnaire’s disease found in adjacent California prisons

Legionnaires’ disease bacteria that killed one inmate and sickened another is more widespread than expected in a California state prison, officials said Wednesday, citing new test results.

Preliminary results found the bacteria in the water supply at a prison medical facility in Stockton and at two neighboring youth correctional facilities, Corrections Department spokeswoman Vicky Waters said.

Officials had thought it was isolated to one housing unit where the two inmates lived. They restricted water use throughout the medical facility and neighboring juvenile facility, bringing in bottled water. But they put special filters only on showers in the housing unit where the inmates had been housed in the California Health Care Facility, which treats about 2,670 inmates needing medical or mental health care.

The neighboring O.H. Close Youth Correctional Facility houses about 150 youths and N.A. Chaderjian Youth Correctional Facility about 260 youths.

No subsequent illnesses were reported and the source hasn’t been found. But officials now are adding the shower filters in other areas and warning against using unfiltered water throughout the three facilities.

“We are responding to preliminary findings and recommendations,” Waters said in an email. “We are still awaiting the final findings and working on a remediation plan.”

That includes deciding how they will clean out the bacteria from the facilities’ water system and how much it might cost, she said.

The bacteria weren’t detected in the Stockton city water supply, though the city supplies water to the state facilities.
