Infection is caused by breathing in small droplets of water contaminated by the bacteria. Common symptoms include coughing, breathlessness, high fever, muscle aches and headaches and usually ...
Legionella bacteria grow best between temperatures of 20°C–45°C with optimum growth temperature being 35°C–40°C. High temperatures (minimum 60°C) kill the bacteria. Legionnaires’ disease can affect anyone. People with immunosuppressed systems, the elderly or people suffering from respiratory problems may be particularly vulnerable.

A specific strain of legionella bacteria (L. pneumophila) can cause a Legionellosis infection in susceptible individuals and presents the most serious hazard.
Legionella control can be achieved by; Keeping water systems clean Preventing stagnation, and Maintaining water temperatures that prevent or minimise Legionella growth. Remember; Legionella control will only be achieved if all the control measures are in place. Review and update Risk assessment.

Agents are classified into 4 risk groups according to their level of risk of infection and can relate to bacteria, fungi, virus, parasites etc. These groups are: A "group 1 biological agent", means one that is unlikely to cause human disease to employees. A "group 2 biological agent", means one that can cause human disease and might be a hazard ...
