Using model miniature ham as a high-throughput tool to screen antimicrobials targeting l. Monocytogenes
The foodborne pathogen Listeria monocytogenes can be transmitted through eating contaminated foods, with outbreaks associated with ready-to-eat (RTE) products, such as deli ham, turkey, and hot dogs. Luncheon meats are often formulated with antimicrobial agents to limit the growth of this …
