The purpose of this study was to investigate the antibacterial effect of films on shelf-life and microbiological Safety of pork meat. Effects of antimicrobial films against total aerobic bacteria, Escherichia coli O157:H7, Listeria monocytogenes, Salmonella Typhimurium, Staphylococcus aureus in pork meat were evaluated during storage of 14 days at 5℃, 10℃ and 15℃. Antimicrobial films were developed with addition of a natural substance, wasabi extracts (Wasabia japonica). At 5℃ storage, growth of total aerobic bacteria, E. coli O157:H7, L. monocytogenes were inhibited higher than at 10 and 15℃. Especially, the numbers of S. Typhimurium and S. aureus were increased gradually at 5℃ even in the control sample, and it takes more than 14 days to increase in every sample upto 6 log10 cfu/g. The higher antimicrobial effects of the films were observed at storage of 5℃ than at 10oC and 15℃. There was a limit of a single treatment of antimicrobial film to prolong shelf-life of pork meat. The synergistic effect of antimicrobial film were observed with addition of refrigeration at 5℃.
