The slaughter to cutting pork process selects Listeria monocytogenes strains by differential ability to form biofilms. Further analysis to asses the virulence potentiel

Listeria monocytogenes is a pathogenic bacteria for human that can be found in food including meats. despite of many other bacteria, L. monocytogenes can grow at low temperatures like those in our fridges, this can causes a serious public health problem. The other complication with L. monocytogenes is that it can adhere irreversibly to food processing plant surfaces and thus facilitate food contamination. During listeriosis outbreaks, the pig meat is often involved, my project aims to identify places in slaughterhouses where this unwanted bacterium persists despite cleaning and desinfection. For that, i have two objectives : a) Understand the ability of listeria to adhere to cutting boards for meat : b) Differenciate L. monocytogenes strains according to there virulence levels. My results will help manufacturers to ensure a safety food products by taking the necessary precautions to keep food protected from Listeria hazards that can increase human health risks.
