Abstract: Abstract This study focuses on the efficacy of dielectric barrier discharge (DBD) plasma treatment (1.1 kV, 3 mm distance, N2 1.5 L/min) as a non-thermal intervention to reduce non-pathogenic Escherichia coli and E. coli O157:H7 in oysters (Crassostrea gigas). Exposure times of 10–30 min by the plasma against non-pathogenic E. coli and E. coli O157:H7 resulted in a log reduction of 0.31–1.01 and 0.18–0.62, respectively, in fresh oysters. In particular, exposure to DBD plasma for 60 min indicated 2.14 log reduction (99.28% reduction) of no...
