Inactivation of Listeria monocytogenes on agar and processed meat surfaces by atmospheric pressure plasma jets

► Pathogen inactivation of atmospheric pressure plasma (APP) jets was investigated. ► N2 + O2 gas mixture was the best for inactivation. ► APP jets were effective for inactivation of Listeria monocytogenes on meat surfaces. ► Shelf-life extension was also expected by APP jets.
