Water sources in the Karratha Health Campus are being treated for legionella after traces of the potentially fatal bacteria were detected in the building.

The WA Country Health Service confirmed the bacteria had been discovered following recent scheduled testing.

WACHS chief executive Jeff Moffet said the bacteria posed a very low risk to patients and staff and he expected all traces to be cleared in the next few days.

“Remediation has been undertaken and included the flushing of water lines and treatment of negative pressure rooms with chlorine,” he said.

“Under public health advice, several other precautions have also been taken and will remain in place until confirmation is received that the facility is clear of legionella – something we expect to occur in the coming days.”

“The hospital remains operational and anyone requiring hospital services should access it as normal.”

Legionella is a type of bacteria that can become established in water systems and can cause Legionnaires’ disease if inhaled.

The bacteria is routinely tested for and, if necessary, treated.
