ROCKHAMPTON Hospital and the Mater Misericordiae Hospital have tested negative to the potentially deadly Legionella bacteria.
Queensland Health released the results of the hospitals yesterday.
Fourteen samples were tested from the Mater and six were tested from Rockhampton Hospital.
There are more results expected for Central Queensland hospitals to be released next week.
Of the 241 facilities that have released their results so far, 29 have returned a positive test for Legionella pneumophila.
Acting Chief Health Officer Dr Stephen Lambert said the detection of the bacteria in hospitals was expected, and did not give cause for concern.
"We believe there is no risk to patients or staff and we have not had a case of hospital-acquired Legionnaires' disease since the two cases at the Wesley Hospital," Dr Lambert said.
The Mater Hospitals in Gladstone, Mackay and Bundaberg also tested negative to the bacteria.
