Legionnaires’ disease is a pneumonia like illness caused by the Legionella bacteria and can be fatal. The infection is caused by breathing in small droplets of water contaminated by the bacteria. The disease cannot be passed from one person to another.
Legionella bacteria are found in the natural environment and may contaminate and grow in water systems, including domestic hot and cold water systems. They survive low temperatures and thrive at temperatures between 20 – 45°C if the conditions are right. They are killed by high temperatures at 60°C or above.
The outbreak of Legionnaires Disease in the Renfrew area, plus the Edinburgh outbreak in 2012, brought the risk of legionella into our consciousness. It is the case that private landlords have an obligation to carry out legionnaires risk assessments of water systems within their rental properties.
