This study was conducted to investigate the microbial loads in mulberry fruits depending on cultivation environment and fruit ripeness. The population levels of total aerobic bacteria in mulberry fruits collected from open field orchards were higher than those from three plots protected within plastic green houses. In regards to fruit ripeness, the levels of total aerobic bacteria in ripe black fruits were higher than those in unripe green and red mulberry. From the farms into where livestock animals were allowed to enter, Escherichia coli was detected in soil at a level of 4.26~4.94 log CFU/g and in mulberry fruits at 5.03~6.07 log CFU/g, while no coliform and E. coli were detected from where the intrusion of livestock was prevented. We also examined the density change of inoculated E. coli in mulberry fruits as they were becoming mature. While E. coli did not increase in green fruits, two and four log CFU/g increases at 20oC and 37oC, respectively, were observed with red and fully mature black mulberries during 48 hours incubation. To ensure the food safety of mulberry, it is suggested that the introduction of E. coli into a farm through livestock should be prevented and more hygienic caution should be taken especially when the fruits are ripe.
