Genetic diversity of Listeria monocytogenes strains isolated from pork products

The SafePork conference series began in 1996 to bring together international researchers, industry, and government agencies to discuss current Salmonella research and identify research needs pertaining to both pig and pork production. In subsequent years topics of research presented at these conferences expanded to include other chemical and biological hazards to pig and pork production.
Listeria monocytogenes (Lm) is an ubiquitous bacterium that causes a foodborne illness, the Listeriosis. PFGE-based studies revealed low genetic diversity among 126 strains isolated from pork products from 2000 to 2001, in France. 78% of these strains displayed two AscI PFGE profiles “a1” and “a2”, which were pork specific, in comparison to clinical strains during the same period1.
