Water is a precious natural resource whose quality is vital for human and animal health. It is also one of the main sources of contamination in the manufacture of food products – whether as an ingredient or as a result of industrial processing.


Ensuring food safety and quality depends upon accurate and reliable water testing. Mérieux NutriSciences performs a range of water quality tests to safeguard food and beverage products as well as manufacturing processes.

From drinking water to wastewater, Mérieux NutriSciences offers the services of our specialized, fully accredited labs for the bacteriological and chemical analysis of water at every stage of the food supply chain. We also conduct water tests to ensure the quality and safety of water in recreational and leisure installations such as pools, spas and saunas.

Environmental standards 

As part of the services carried out by our Water and Environment specialists (link to Water and Environment), we perform analyses of groundwater used for human consumption to safeguard against potential contamination by industrial pollution and landfills. We also conduct sample collection and analyses of surface waters and treated water for public supply in order to ensure full compliance with current legislation.

Sensory analysis of water 

Organoleptic properties like taste and smell are key to developing products that will appeal to consumers in the food and beverage sector. We offer a full range of analytical and consumer research services on water and water products as part of our specialized Sensory and Consumer services (link to Sensory Analysis).
