Historical statistic data shows that seafood have been argued as the main medium for Vibrio parahaemolyticus which cause most cases in foodborne outbreaks and this trend is increasing. From food safety viewpoint, there is a need to understand more about the purchase environment of seafood, and its fatal importance on foodborne outbreaks. To ensure the quality of seafood safety, the number of bacterial pathogens and their pollutions must be controlled and inhibited. E. coli and aerobic plate count have been suggested as two key factors to measure seafood safety. This research aims to create an Epidemiology Monitor Network based on local descriptive data collected from different kinds of seafood bacteria distribution, and safety condition。From August 2007 to January 2008, we collected 252 sample data from traditional market, warehouses, and supermarket in 12 official administrative areas in Taipei. The results show that the records found for Vibrio parahaemolyticus is 103 (rate = 40.9％), E. coli is 80 (rate = 31.7％), and; Aerobic plate count is grater than 105 as 185 (rate = 73.4％). Through Kanagawa test, the 103 Vibrio parahaemolyticus records all show positive reaction. Based on Kanagawa phenomenon, the result suggests that Taiwan is higher than other countries in Vibrio parahaemolyticus. In Vibrio parahaemolyticus, we inspected Bivalves and found the highest rate as 60.％, Shrimp the middle rate as 52.3％, and Fish the lowest rate as 22.8％。In traditional market, the rates for Vibrio parahaemolyticus, E. coli, and aerobic plate count are significantly found as 51.2％, 38.0％, 79.3％ respectively. The records are found as the highest than those in warehouses as 40.5％、31.1％、71.1％, and supermarket as 26.7％、23.3％、66.3％。
