There were no other significant sources of aerosolized water - small droplets of water or mist that can be inhaled - at the event center, and no other ongoing potential sources of exposure identified, the health department said. The department says 124 cases have been reported so far. Very little aerosolized water is created from hand washing sinks, toilets and other now operating water sources at the Agricultural Center, meaning the risk of exposure to Legionella is low. According to the Centers for Disease Control and Prevention (CDC), faulty plumbing systems, contaminated air conditioning units, cooling towers, and hot tubs are common sources where the bacteria can be heavily concentrated.More news: Robert Forster: Jackie Brown star dies aged 78
