Résumé

Bologna and salami slices were inoculated with Listeria monocytogenes then stored for 82 days at 4°C. They were then exposed to a simulated dynamic model of the stomach and the small intestine. Although salami had potential effects against gastric killing of L. monocytogenes, the high and low contamination levels in bologna and salami during storage were by far the dominant findings. The results indicate that simulation of gastrointestinal conditions is vital in order to acquire knowledge of the gastrointestinal survival of pathogens.
