Listeria monocytogenes is problematic for the manufacturing, storage, and consumption of ready-to-eat foods. This bacterium may cause listeriosis upon consumption often with deadly complications. Queso Fresco (QF), a pasteurized Hispanic-style fresh cheese (HSFC), has been shown to support the growth of L. monocytogenes. QF is the most widely produced and implicated HSFC in the U.S., representing a significant health hazard to at risk populations such as infants, pregnant women, elderly, and the immunocompromised. The objective of this research project is to evaluate the efficacy of ten novel antimicrobial endolysins in combatting L. monocytogenes contamination in a miniaturized lab-scale queso fresco model over a 28 day shelf life.
