Abstract

Fresh-cut apples contaminated with either Listeria monocytogenes or Salmonella enterica serovar Poona, using strains implicated in outbreaks, were treated with one of 17 antagonists originally selected for their ability to inhibit fungal post harvest decay on fruit. While most of the antagonists increased the growth of the food-borne pathogens, four of them proved effective in preventing the growth or survival of food-borne human pathogens on fresh-cut apple tissue.

Abstract

The authors describe their study of Listeria monocytogenes. They have determined the survival and growth of L. monocytogenes on fresh-cut honeydew melon and apple slices at an abusive temperature, and have investigated the effectiveness of lytic phages in controlling L. monocytogenes contamination on fresh-cut fruits.
