Mérieux NutriSciences laboratories determine the microbiological contamination (bacteria, fungi, etc.) on specific culture media through the use of SAS sampler for the detection of the microbiological airborne component or by means of swabs or contact plates for the assessment of the microbiological component on the surfaces. The verification of the contamination of sites under investigation leads to define and identify possible risks for workers.

Downloadable Chain of custody
The Chain of custody is a document of fundamental importance to correctly manage samples information during sampling, transport, analysis and reporting. It guarantees the traceability of every sample. Mérieux NutriSciences offers templates that can be downloaded from the website and then filled in to accompany samples.

Microbiological parameters
The determination of microbiological contamination (bacteria, fungi, etc.) on specific culture media and through a SAS sampler for the detection of the microbiological component -by means of the airborne or contact pads or plates for the evaluation of the microbiological component on surfaces- is of fundamental importance for the verification of the microbiological contamination of the places under investigation. The activities of Mérieux NutriSciences define and identify possible dangerous situations for workers.

It is a ubiquitous organism that especially proliferates in hot water environments, between 32 and 45 °C. Legionella infection is not transmitted from person to person, but it is rather transmitted via aerosol and contaminated water, as in the case of a conditioned environment or with humidifiers. The bacterium mostly reproduces in humid and warm or heated environments -such as piping systems, condensers, water cooling piping-, and then it forms a kind of bacterial film. For this reason, Legionella infection is a serious public health problem because it is an element of risk in all situations in which people gather in the same environment, as occurs in nursing homes, retirement homes, hospitals, swimming pools and spas and other public places where an air conditioning system or humidification of air treatment or water re-circulation are operating. Mérieux NutriSciences offers analyses for the determination of Legionella.
