20Gas plasmas generated at atmospheric pressure and ambient temperatures offer a possible 21 decontamination method for poultry products. The efficacy of cold atmospheric gas plasmas 22 for decontaminating chicken skin and muscle inoculated with Listeria innocua was examined. 23Optimization of operating conditions for maximal bacterial inactivation was first achieved 24 using membrane filters on which L. innocua had been deposited. Higher values of AC 25 voltage, excitation frequency and the presence of oxygen in the carrier gas resulted in the 26 greatest inactivation efficiency, and this was confirmed with further studies on chicken 27 muscle and skin. Under optimal conditions, a 10 s treatment gave > 3 log reductions of L. 28innocua on membrane filters, an 8 min. treatment gave 1 log reduction on skin, and a 4 min.
