This project aims at characterizing and better understanding the behavior of viable bacterial flora that is transferred inside fish and on industrial surfaces after having undergone stress linked to the procedures of N&D, or processing.

It is important to study viable bacterial flora, and specially the VNC part that is still little known in the industry of fishery products, because it represents a major problem at the health level. In fact, VNC bacteria cannot be detected using classic microbiological techniques, but they are still potentially pathogenic under the right conditions, knowing that the disease transmitted via food, including listeriosis, have of course a significant human and economic cost. This project comes as a continuation of studies performed for better understanding of the microbial risk in the industry of fishery products, by basing itself on molecular techniques that have been developed for detecting viable bacteria populations.

This project has the purpose of allowing companies to manage promptly the threat from VNC forms to limit risks of contamination and possible withdrawal of contaminated batches, which give a negative image of the company involved and/or the industry in general. Moreover, contamination of surfaces by microbial stains is a common problem in the agrifood industry, leading to significant financial losses. Besides this economic aspect, it is important to note that the consequences in terms of public health remain at a significant level since 25% of food poisoning cases are linked to contamination during the food processing procedure. It appears therefore necessary to quantify the bacteria/substratum transfers, and to determine how VNC bacteria population transfer develops in a food item.
