Health Protection Agency conference highlights spa pools as a cause of legionnaires’ disease

“It’s been assumed that if the pool water is satisfactory for routine microbiological checks then growth and spread of Legionella would also be under control. But we discovered that the Legionella bacterium, may be present in high numbers in both privately owned and public facilities even when routine microbiological and safety checks appear satisfactory.
