An apparatus for generating atmospheric pressure plasma (APP) jet was used to investigate the inactivation of Listeria monocytogenes on the surface of agar plates and slices of cooked chicken breast and ham. He, N<SUB>2</SUB> (both 7 L/min), and mixtures of each with O<SUB>2</SUB> (0.07 L/min) were used to produce the plasma jets. After treatment for 2 min with APP jets of He, He + O<SUB>2</SUB>, N<SUB>2</SUB>, or N<SUB>2</SUB> + O<SUB>2</SUB>, the numbers of L. monocytogenes on agar plates were reduced by 0.87, 4.19, 4.26, and 7.59 log units, respectively. Similar treatments reduced the L. monocytogenes inoculated onto sliced chicken breast and ham by 1.37 to 4.73 and 1.94 to 6.52 log units, respectively, according to the input gas used with the N<SUB>2</SUB> + O<SUB>2</SUB> mixture being the most effective. Most APP jets reduced the numbers of aerobic bacteria on the meat surfaces to <10<SUP>2</SUP> CFU/g, and the numbers remained below that level of detection after storage at 10 <SUP>o</SUP>C for 7 days. The results indicate that APP jets are effective for the inactivation of L. monocytogenes on sliced meats and for prolonging the shelf-life of such foods.
