Recently, the sanitary importance of food poisoning bacteria was reported in many literature. The environmental factors such as temperature. pH, salinity and organic material were reported as important factors in determining detection rate and density of these bacteria. Thus, experimental study were conducted in order to evaluate the influence of environmental factors on detection rate and density of these bacteria. Fifty four fresh water samples and 55 bottom deposit samples from Mije pond in Kunsan from June 1996 to May 1997 were used for this study. The detection rate of Vibrio cholerae non-O1 were 50.9% for fresh water and 47.3% for bottom deposit and those of Vibrio mimicus were 34.5% and 38.2%, respectively. The total detection rate of 'Vibrio cholerae non-O1 (49.1%) was higher than that of Vibrio mimicus (36.4%), Vibrio cholerae non-O1 were only detected in fresh Water and bottom deposit from May to October when the water temperature was 20℃ above but Vibrio mimicus were detected in fresh water and bottom deposit from July to September when water temperature was 25℃ above. Vibrio cholerae non-O1 and Vibrio mimicus were detected even in bottom deposit .on the February when the water temperature was 6.2℃ but these bacteria were not deteted in fresh water in cold weather. From these results, we supposed that temperature and organic material in aquatic environmental condition were one of the most important factors in determining detection rate and density of Vibrio cholerae non-O1 and Vibrio mimicus.
