Listeria monocytogenes is another major concern to the food industry, due to its inherent resistance to several preservation practices and the high mortality rate of listeriosis in susceptible populations. Of particular concern is its ability to grow at refrigeration temperatures and on dry surfaces, and to tolerate acidic conditions (Barker and Park, 2001).
