I am informed that:
(1) (a) Nil
(2) (a) Both the detections of Legionella were from samples collected from the Edward Wilson Building
(b) In 2012 the Legionella level was 10 cfu/ml in 2013 it was 27 cfu/ml
(c) Legionella has not been detected in any air conditioning or cooling system
(i) In 2012 and 2013 approximately one staff member was potentially exposed. No patients were exposed.
(ii) Following the detection of Legionella on both occasions the system was disinfected with hot water. People were prevented from showering until the follow up sample showed no Legionella was detected. Following the detection in 2012 a review of the system was conducted.
(iii) All staff were informed following both detections.
