Identification of the microbial ecosystem components in pigmeat production areas associated with the absence of Listeria monocytogenes. Towards a surfaces directed ecology.
I study Listeria monocytogenes on pork production areas in slaughterhouses. L. mono is the etiologic agent of listeriosis, a foodborne illness that can cause serious health problems. It has been shown that in slaughterhouse’s production from one stage to another some strains outweigh others and can become persistent and thus increase the chance of product contamination. The hypothesis to explain the persistence of some strains is that the presence of specific bacteria can influence the presence of L. mono. I try to describe the microbial population present on the surfaces. I also want to detect associations of the presence of the pathogen with microbial determinants of the community and confirm those relations in laboratory. My work is part of an ecology directed perspective to provide an assessment risk model of contamination of a product by L. mono.
