Managing and Controlling the Risks of Legionella in Care Homes

Legionella Stansted Laboratories

Legionella bacteria is commonly found in water and especially in purpose-built water systems such as cooling towers, evaporative condensers, hot and cold water systems and spa pools as well as water fountains. The bacteria can multiply where water temperatures are between 20-45°C whereas the bacteria is normally dormant below 20°C and does not usually survive above 60°C.
