Pool closed after legionella found
A spa pool at the Onehunga War Memorial Pool and Leisure Centre will be closed for weeks following the detection of legionella bacteria.
The Auckland Council-owned facility closed a spa pool on July 5 following word from the Auckland Regional Public Health Service (ARPHS) that the bacteria had been detected in a water sample. Chief operations manager Arvid Ditchburn said the spa would remain closed for up to three weeks while ARPHS carried out tests.
Auckland University associate professor Simon Swift said the bacteria could cause two diseases, Pontiac Fever and legionnaires disease. The latter could be a serious and potentially fatal infection, he said.
‘‘Most people exposed to the bacteria do not get sick and it is treatable with antibiotics, but the bacteria causing the infection does need to be identified,’’ Swift said.
‘‘Heat above 60 degrees kills this bacteria, a good flow of water without stagnant areas stops it colonising and cleaning the pipes and removing any slime that might grow should get rid of it.’’
The period between exposure and onset of symptoms is usually two to 10 days. Ditchburn said there were no immediate risks to contamination in the other pools, but the spa would not re-opened until a negative test was returned.
