Despite to the reality that the outbreaks from food poisoning in Korea have been continuously increasing in the last two decades, it was very much neglected even in the public health field in Korea. Food poisoning outbreaks resulted in many cases not only in the damage of health but also in the death of many lives. However, this problem can be effectively solved by efforts through health education activities, but not solely by the legal measures. This study was carried out to provide information that can be used in planning health education programs and proposing new rules to prevent any possible outbreaks from food poisoning. The main problems contributing to food poisoning outbreaks in an institutional setting or school catering and at home were reviewed and analyzed through the epidemiological investigations and articles related to food poisoning in the last a decade (1991-2000). Accordingly, the data presented in this study are sufficient to show and prove the significant trends in food poisoning accidents in Korea. The major findings investigated in this study are as follows. The frequency of food poisoning accidents as well as the number of victims have continuously increased in Korea. The number of victims per food poisoning accident is also increased from 20 persons in 1990 to 69.8 persons in 2000. Therefore, we should realize that the group poisoning outbreaks occur more frequently and the size of group poisoning accidents is getting larger. Among four seasons, the food poisoning accidents occurred more frequently in the summer (May-September) until 1997. However, after 1997, the food poisoning accidents occurred evenly in three seasons except the winter. The most important bacteria that cause food poisoning in Korea were Salmonella spp., Vibrio spp. and Staphylococcus aureus. They occupied 85-90% of the rates of accidents and the number of victims. And, the major category of food causing outbreaks in Korea are meats, raw and undercooked sea foods and compound food as Kimbab and lunch box. Among meats, the most food poisoning accidents were caused by pork. The frequency of food poisoning accidents at individual households tends to decrease continuously. Whereas, the rates of accidents at the public restaurants and food service establishments are comparatively increasing. Therefore, we must improve the quality of the sanitation management in food service establishments through HACCP and post- administration of HACCP.
