THE latest round of testing at Hervey Bay Oral Health and Cancer Care Centre has confirmed legionella is no longer present in the hot and cold water system of the building.
The bacteria was first detected in December in the centre's water system.
The building was systematically treated by the Wide Bay Hospital and Health Service on three occasions after legionella was detected in two hot water taps, then in two cold water fountains.
"During the latest testing, a single legionella detection was found in a staff room sink tap head, which has since been replaced," a WBHHS spokeswoman said.
"In the past two months, more than 500 water samples have been taken across Wide Bay Hospital and Health Service facilities as part of our Water Quality Risk Management Plan, which is considered a leader in water quality testing across the state.
"The WBHHS is committed to ensuring water quality within our facilities is of the highest standards and meets both state and national guidelines."
At the time of the discovery of the bacteria, Wide Bay Hospital and Health Service's chief executive Adrian Pennington said that legionella was a naturally occurring bacteria that all health services needed to manage.
The positive test results at the Hervey Bay Oral Health and Cancer Care Centre follows an outbreak of the bacteria at Hervey Bay Hospital in May last year.
The hospital was cleared of legionella 17 days after it was discovered in the hospital's water system on May 19.
A patient who died at the hospital was found to have legionella on April 20, prompting further checks regarding the water supply.
