Data sheet

Contexte de l'analyseLegionellosis is a serious pneumonia caused by bacteria (Legionella) which can develop in the domestic hot water network (DHW). Contamination occurs by inhalation of aerosols, for example in the shower.
RèglementationEstablishments Receiving the Public (ERP) are required to have an annual check by a COFRAC accredited laboratory (sampling + analysis). Note: For regulatory control of LES, the sampling must be carried out by an accredited laboratory COFRACInovalys performs the analysis of your domestic hot water in accordance with the official method appearing in the regulations in forceSee "Download" section below.

Why do I have to test the water in my shower (Legionella)?

Analysis is a way of reassuring oneself about the "Legionella" risk that is regularly reported in the media.

Any network of Domestic Hot Water, private or collective, can be the place of proliferation of Legionella, especially if the temperature is below 55 ° C, if the installation is aging, if there is a large storage tank, or if the network is little used and if the shower heads are dirty or corroded.

Fortunately, the sensitivity of individuals is very variable towards this infectious agent and most people do not develop Legionellosis when they are in contact with contaminated water. Factors increasing this sensitivity are age (over 50), alcohol and tobacco use, immunosuppression.

Approximately 1000 cases of Legionellosis are declared annually in France (notifiable disease), of which almost 10% are fatal.

Description of the analyzes carried out by the laboratory

Legionella pneumophila: It is, in France, the species of Legionella responsible for the majority of cases of Legionellosis. French regulations only relate to this species.

Legionella spp: All Legionella species combined. In the absence of Legionella pneumophila, the presence of other Legionella remains an indicator of the risk of potential proliferation.


Inovalys performs the analysis in accordance with AFNOR NF T90-431, the only officially recognized method for controls. It requires at least 8 days of incubation (more if suspicion of presence). Any proposal to analyze Legionella in a shorter time means that another method is used.

There are faster methods, the results of which are not very comparable and more difficult to interpret. Inovalys is able, for example, to carry out Legionella counts if necessary by the Molecular Biology "PCR" method, with results in 72 hours, or even less in the event of a health crisis.
