Three pork fabrication processing were examined for isolation and serotyping of Listeria monocytogenes. Three hundred thirty samples were collected from gloves, knife sharpeners, knives, cutting boards, conveyer belts, skinning machines, working room air, pig carcasses, and cut meat. Among the 234 samples taken from processing environment, the isolation rates of Listeria monocytogenes and other Listeria spp. were 17.5%, 34.2% respectively. Isolation rates of Listeria monocytogenes from different specimens during processing were 20.8% in gloves, 21.3% in knife sharpeners, 14.6% in knives, 20.8% in cutting boards, 28.6% in conveyer belts, 16.7% in skinnig machines. Listeria monocytogenes and other Listeria spp. were not detected in working room air. Isolation rate of Listeria monocytogenes 14.6% in pork was increased compared to that of 8.5% in pig carcasses (p$lt;0.05). The serovars of 41 isolates from processing environment were 4b 36.6%, 1/2a 24.4%, 4ab 17.0%, 4a 4.9%, 1/2c 2.4%, and 4c 2.4%. The serovars of 4b, 1/2a, 4ab were detected from carcassess and cut meats.
