Given the facts that concentrations of antimicrobials in RTE meats differ from lot to lot and the deli counter is one of the critical contamination/cross-contamination sites, new techniques that can prevent Listeria contamination and inhibit the Listeria growth during the
deli counter or consumer home processing/storage are needed. In the last decade,researchers evaluated various means of improving the safety of deli meat products, including using antimicrobial packaging, films, or coatings, applying antimicrobial treatments
such as organic acids and bacteriocin prior to final packaging, or employing post-packaging pasteurization such as high pressure and thermal treatments
