Why is it important?

Legionella bacteria are potentially present in all domestic hot water systems and cooling towers, causing fatal respiratory diseases when they are poorly maintained or too old. There are more than 50 species of legionella, including legionella pneumophila, which accounts for 80% of pathologies. Although the entire population may be affected, immunocompromised persons or those with breathing difficulties are the major targets of the disease. Infection occurs after the inhalation of contaminated aerosols.

Two methods of normative analysis make it possible to demonstrate the presence of these bacteria. The regulations specify how to use them. The DGS (Directorate-General for Health) circular of 21 December 2010 (DGS / EA4 / 2010/448) and the Order of 1 February 2010 impose on establishments open to the public, the duty of conducting analyses to detect Legionella and establishing a health file. This circular makes the manager of the establishment legally liable for the quality of the water supplied. The occurrence of Legionella cases results in an investigation by the competent authorities and the systematic closure of the establishment during disinfection and the counter-analysis period (15-20 days).
