The creation of the “Metabiot: Use of massive data to improve food safety” contracted unit (USC) was made official on 28 February 2022 at the Paris International Agricultural Show, when the agreement to that end was signed by Olivier Faron, General Administrator of the CNAM, and Roger Genet, Director General of ANSES. The USC, which will run for a renewable three-year period, had been included in a framework agreement signed by ANSES and the CNAM in 2021.
The aim of Metabiot is to study the role of microbiota (communities of micro-organisms), in conjunction with the metabolome (the complete set of metabolites produced), in the foodborne transmission of bacteria posing risks to humans. The studies undertaken will rely on the development of tools for the acquisition and analysis of massive data. The unit’s research will encourage measures to reduce the use of medicinal products and biocides in animal and food production sectors. It will also provide input for discussions on how to improve animal feed and make better use of massive data in the food processing industry.
Studying zoonoses from farm to fork
The joint research team will study interactions between bacteria that pose risks to human health and their hosts, all throughout the food production chain. The objective is twofold:
- optimise animal feed in order to limit levels of bacteria transmissible to humans in their digestive system;
- better understand the interactions that occur between the microbiota contained in products such as meat and that found on surfaces in agri-industrial environments, in order to determine what role they play in the circulation of pathogenic bacteria.
Complementary skills relating to the food industry
The Metabiot USC will bring together the Hygiene and Quality of Poultry and Pig Products (HQPAP) Unit of the ANSES Ploufragan-Plouzané-Niort Laboratory, led by Marianne Chemaly, director of research projects, and the Agri-food Chair of the CNAM, placed under the responsibility of Philippe Fravalo, professor and CNAM chairholder. Both entities are based in Ploufragan, in the Côtes-d’Armor département. Therefore, Metabiot will be supported by the Bretagne region, the Côtes-d’Armor département and the Saint-Brieuc urban community, to facilitate the hosting of doctoral and post-doctoral students.
The HQPAP Unit will provide its expertise on foodborne zoonotic bacteria in the poultry, pig and cattle sectors. Its research aims to gain insight into bacterial circulation, identify sources of contamination, and understand how zoonotic bacteria interact with their hosts, to improve the methods used to combat infections.
The CNAM's Agri-food Chair, supported by its biology team, has expertise in the acquisition and analysis of massive data in the food processing industry, in particular for the poultry and pig sectors but also for crop production. Based on an analysis of vast amounts of data, the use of artificial intelligence will help make connections and identify indicators associated with the transmission of these zoonotic bacteria in various production sectors; these may include the genomes of all of the bacteria present, or the metabolites of bacteria or animals.
