Rooted in Science

Marcel Mérieux, grandfather to Board Member of Mérieux NutriSciences, Alain Mérieux, first studied biology under Louis Pasteur. In 1897, he founded an analysis laboratory in Lyon, France that would become the prestigious Institut Mérieux. It was in this laboratory that Marcel Mérieux developed the first antitetanus sera.


Dr. Charles Mérieux

In 1937, his son, Dr. Charles Mérieux, took up the reins of his father’s laboratory after his death. In the 1940's, he introduced a technique developed by the Dutchman Frenkel - in vitro culture – which revolutionized the manufacture of vaccines and led to the production of reagents for in vitro diagnostic testing.

Initially under the direction of Dr. Charles Mérieux (Marcel’s son) and later Alain Mérieux (Marcel’s grandson), Institut Mérieux became a world leader in the field of human and veterinary vaccines.

The family's corporate holding was later extended in the 1990s to address food safety and nutrition issues, through the acquisition of American food testing company Silliker. It was this acquisition which later resulted in Mérieux NutriSciences.

Food safety and nutrition are major public health challenges that are integrated in public health policies in many countries. More broadly, protecting health entails the security of products that could, in their daily use, risk the health of consumers.


Dr. John H. Silliker

Silliker is the historical pillar of Mérieux NutriSciences and a pioneer in the field of food safety and quality. The company was created in 1967 in the United States by Dr. John H. Silliker, a microbiologist known for his work on Salmonella, who began his own business with a staff of just four people. With its headquarters in Chicago (Illinois), the company has grown rapidly in recent years and now operates nearly 100 laboratories in 21 countries.

With over 50 years of experience in food safety and quality, Mérieux NutriSciences has won the confidence of the food industry and extended its expertise to several industrial sectors across the globe including: Water and Environment, Pharma and Medical Devices, Personal Care and Cosmetics, AgroChemicals and Consumer Goods.

Mérieux NutriSciences is also increasing its presence in emerging countries, in particular in China, Brazil, Turkey, South Africa and India, with the purpose of answering these countries’ growing demands.

Today, Mérieux NutriSciences works with clients as a trusted partner to promote public health through analysis, consulting, auditing, training, contract research and sensory analysis services.

An integral part of Institut Mérieux, Mérieux NutriSciences contributes to advancing science and addressing the concerns of manufacturers through a uniform approach of quality.

The Fondation Mérieux

The Fondation Mérieux was established in 1967 by Docteur Charles Mérieux, in honor of his father, Marcel Mérieux. It was awarded official charitable status in 1976.

The Fondation Mérieux is an independent family foundation. Each successive generations sharing common values in the Pasteurian tradition, have succeeded in passing on their vision of biology serving public health worldwide.

By bringing together partners with a wide range of skills and cultural backgrounds, Dr. Charles Mérieux has succeeded in creating an exceptional international network. Fondation Mérieux has thus played a unifying role catalyzing initiatives with the common goal of fighting infectious diseases worldwide.

Under the impetus of Alain Mérieux and Docteur Christophe Mérieux, the Foundation has refocused its action in the field at the heart of infectious areas, with the support of Fondation Christophe et Rodolphe Mérieux.
