Legionella Services

Mérieux NutriSciences accredited laboratories offer a wide range of services to help businesses avoid legionella contamination.

Legionella bacteria are found naturally in low numbers in water bodies such as rivers, lakes, and reservoirs in temperatures between 20°C and 60°C. Since they are naturally in the water they end up entering man-made water distribution systems where they can then reproduce and thrive on the nutrients available and the favorable conditions within these systems. The organism is able to infect humans when water is aerosolized (airborne droplets) and the organism is dispersed along with these aerosols.

Our Services

Legionnaires’ Disease is a form of pneumonia that can be potentially fatal. Certain sections of the general population are more susceptible to the organism, those such as the elderly, immunosuppressed and immunocompromised persons, people with health conditions, and smokers.

Water systems that pose the greatest risk to the public are those systems that aerosolize potentially contaminated water, including cooling towers, spas, showers, fountains and garden sprinkler systems, etc. For example, cooling towers can spread aerosols in the air up to a 7km radius from the unit, depending on the atmospheric conditions.

With this in mind, Mérieux NutriSciences offers a range of services, designed to assist you with the monitoring and management of Legionella.  

*These services are not conducted on-site in Malaysia but can be outsourced to one of Mérieux NutriSciences’ global network laboratories.
