This study was conducted to investigate the combined effect of lactic acid and various food ingredients for inactivating Escherichia coil 0157:H7 in laboratory media. Luria-Bertani (LB) without NaGl was used for treatment of lactic acid alone or the combination of lactic acid and food ingredients such as 3% NaCl, glucose, sucrose, glycine, vitamin mixture. Also, the combined effects of various NaGl concentrations (1-15%) on treatment of lactic acid against E. coil 0157:H7 were tested. pH and a values were decreased when food ingredients were added into laboratory media containing 1% lactic acid, However, the combination of lactic acid and food ingredients (NaCl, glucose, sucrose, glycine, vitamin mixture) were less effective on killing E coil 0l57:H7 than the treatment of lactic acid alone therefore it showed the antagonistic effect. Among food ingredients, the addition of NaCl and glycine showed the highest antagonistic effect and for NaC1, the concentration of upto 12% resulted the antagonistic effect. From these results, the addition of food ingredients which could be helpful to preserve food due to decreasing a may result the negative effect when they combined with treatment of lactic acid. Therefore, the combined effect of acids and food ingredients should be studied further for inactivating foodborne pathogens in foods.

The market of organic produces which are cultivated without insecticide or chemical fertilizer is growing very fast. However, several food poisoning cases are caused by microbiologically contaminated organic vegetables. Therefore the aim of this research is to compare the microbiological contamination level of organic and inorganic vegetables produced in Korea. Each 10 samples of organic and inorganic vegetables (Chicory, Romaine, Red Lettuce, and Red chard) were collected from retail market and submitted to the microbial evaluation. The number of total microbes, Escherichia coli 0157, Salmonella spp., and Staphylococcus aureus were investigated with the standard methods of Food Code in Korea. Statistical analysis of each group was performed using SAS (version 9.1) program. The average number of total microbes and Staphylococcus aureus in organic vegetables were much lower than that of inorganic vegetables (6.91 vs. 6.44; 7.04 vs. 6.89 respectively) but contamination of E. coli 0157 and salmonella spp. were vice versa. Our data may support that organic vegetables are not free from microbiological contamination which can cause food poisoning.
