Objectives: This study estimated the annual socioeconomic costs of food-borne disease in 2008 from a societal perspective and using a cost-of-illness method. Methods: Our model employed a comprehensive set of diagnostic disease codes to define food-borne diseases with using the Korea National Health Insurance (KNHI) reimbursement data. This study classified the food borne illness as three types of symptoms according to the severity of the illness: mild, moderate, severe. In addition to the traditional method of assessing the cost-of-illness, the study included measures to account for the lost quality of life. We estimated the cost of the lost quality of life using quality-adjusted life years and a visual analog scale. The direct cost included medical and medication costs, and the non-medical costs included transportation costs, caregiver's cost and administration costs. The lost productivity costs included lost workdays due to illness and lost earnings due to premature death. Results: The study found the estimated annual socioeconomic costs of food-borne disease in 2008 were 954.9 billion won (735.3 billion won-996.9 billion won). The medical cost was 73.4 -76.8% of the cost, the lost productivity cost was 22.6% and the cost of the lost quality of life was 26.0%. Conclusions: Most of the cost-of-illness studies are known to have underestimated the actual socioeconomic costs of the subjects, and these studies excluded many important social costs, such as the value of pain, suffering and functional disability. The study addressed the uncertainty related to estimating the socioeconomic costs of food-borne disease as well as the updated cost estimates. Our estimates could contribute to develop and evaluate policies for food-borne disease.

본 연구는 식중독을 일으키는 병원성 미생물들은 식품시료와 교차오염 원인의 지표가 될 수 있는 도마에 접종한 후 오존수와 일반 수돗물을 이용하여 세척한 후 미생물의 변화와 세척방법에 따른미생물의 변화를 각각 비교 관찰하였다. 실험결과 일반 수돗물보다 오존수가 살균효과가 더 높았고, 같은 세척수로 세척 시에도 접종 방법, 실험시료 및 시료의 표면, 균질화에 따라 살균효과가 다르게 나타나는 것을 확인할 수 있었다. 세척방법으로는 침수보다 주수 에서 살균효과가 더 컸으며 오존수의 농도는 0.2 ppm에서 유의적인 살균효과를 나타내었으며 오존수 농도가 0.4, 0.6, 1.0 ppm으로 증가함에 따라 농도 의존적으로 살균효과 또한 증가하였다. 위의 결과들을 통해 0.2 ppm 이상의 오존수가 부패 미생물 제어에 미치는 영향이 크고 식품의 제조 가공 시 여러 안전성 면에 있어서 오존수를 이용한 세척이 효과적이라고 생각된다.

Water- borne infectious diseases can be acquired by contact with contaminated water or by ingestion of contaminated water. There are many water- borne infectious agents such as bacteria, virus, and parasite. Among many of water- borne infectious diseases, health authorities of Korean government has particularly intensified to prevent and control typhoid fever(class I ), shigellosis(class I ), cholera(class I ), paratyphoid fever(class I), amebiasis(class II ) and leptospirosis(euivalent to class II ) under the communicable disease control law. Water- borne disease Prevention and control guideline itself has been also well provided by the health authorities. However, in practical public health point of view, there are still many problems remained to be solved out; no prospective investigation project to survey water borne infectious diseases under the national disease prevention and control programmes, incredible statistic data of annual notifiable disease report frequent appearance and varieties of drug resistance water- borne infectious agents, little cooperation and information- exchange system in between the related government authorities( the health authorities, the environment sanitation authorities and the food hygiene authorities) which should be closely collaborated, lack of health consciousness of the people, necessity of evaluation and Hndification on to the outcomes of performed health activities and programmes, neglect activities for water quality investigation, shortage of expertise and human resources in the related field, and poor investment of the government budget to develope and improve public health and sanitation field. In order to prevent and control water- borne infectious diseases effectively, it is emphasized that all the above indicated should be considered and performed to improve under the national health and sanitation development programmes.

Fishery products were collected in seafood markets located on the southwestern coast of Korea between 2000 and 2004 and examined for the presence of Vibrio parahaemolyticus. This strain was detected in 138 of 843 samples (16.4%) that included dams, eels, crabs, octopuses, and cockles. The number of positive findings for V. parahaemolyticus among fishery products was the highest in dams at 23.6% followed by eels at 22.1%, crabs at 21.1%, octopuses at 18.0%, and cockles at 14.3%. V. parahaemolyticus was detected with overall frequencies of 15.3, 14.8, 13.8, 21.6, and 18.6% from 2000 to 2004, respectively. The monthly occurrence of the organism rapidly increased to over 20% between June and October. The monthly cases of food borne disease caused by V. parahaemolyticus in Korea over the last five years began to increase in August and reached its peak in September. However, the potential for outbreaks of food borne disease caused by V. parahaemolyticus was relatively minor between November and April. Consequently, this study shows that fishery products harvested from June to October must be handled sanitarily in Korea.

Milk and dairy products are not only excellent foods for humans, providing plentiful varied nutrients, but are also a good medium for detrimental food-borne pathogens. Although the food safety field has stabilized due to standardization of food processing, such as the hazard analysis critical control point (HACCP), outbreaks and cases caused by food-borne pathogens still occur at high rates. In approximately 30% of cases, the disease-causing pathogenic organism is undetermined. Recently, a biosensor was developed that has a simple and fast response and overcomes the problems of conventional methods such as cultivation, immuno-assay, polymerase chain reaction, and microarray. Due to the high selectivity and sensitivity of optical biosensors, it is a suitable method for the immediate detection of food-borne pathogens in milk and dairy products.

온천수에는 각종 무기물이 풍부하게 함유되어 있으며 특히 2가 이온들이 많이 들어있고 살균력을 갖춘 유황 성분이 있어, 식중독 및 병원성 미생물의 증식을 억제할 수 있는 가능성이 있다. 온천수의 식중독 및 병원성 미생물에 대한 억제 효과를 시험하기 위하여 식중독 미생물인 Bacillus cereus, Staphylococcus aureus 및 Escherichia coli, 피부병 원인균인 Candida albicans와 Trichophyton mentogrophytes, 위장병 원인균인 Helicobacter pylori을 대상으로 시험하였다. 본 실험에 사용한 온천수는 먹는물 수질기준에 따라 분석한 결과 불소함량이 기준치 1.5mg/L보다 높은 14.1 mg/L로 먹는물 수질기준에 적합하지 않으나 그 외 항목은 먹는물 수질기준에 적합하였다. 몇 가지 식중독 미생물이 온천수에서 생존하는 양상을 관찰한 결과 S. aureus 및 E. coli의 생존에 대해서는 별 영향을 미치지 않았으나, B. cereus의 균수는 감소시키는데 이는 온천수의 온도($41^{\circ}C$와 관계있는 것으로 판단되었다. C. albicans와 T. mentagrophytes등 피부병균과 위염 원인균(H. pylori)에 대해서도 온천수는 뚜렷한 증식 억제효과를 보이지 않으나 T. mentagrophytes는 온도에 영향이 있음을 확인하였다. 이상의 결과를 종합할 때 온천수는 식중독균이나 피부질환 혹은 위염 원인균에 뚜렷한 억제 효과는 나타나지 않으나 일부 고온($41^{\circ}C$)에 의한 균수의 감소 효과는 인정 되었다.

Food handling practices playa key role in the prevalence of food-borne illness. Despite the fact that pregnant women are high risk groups for food-borne disease, little is known about their actual food handling practices at home. The objective of this study was to investigate behaviors regarding food-related hygienic practices of pregnant women. The questionnaire included questions in five major areas : personal hygiene ; adequate cooking ; avoiding cross contamination ; keeping food at safe temperatures ; and avoiding food from unsafe sources. Analysis of 488 questionnaires showed the respondents were unaware of the importance of safe food handling practices. Especially, pregnant women in our study should be encouraged to be careful about either risk of adequate cooking $(2.08\pm0.66)$ and keeping foods at safe temperatures $(2.69\pm0.63)$. Residency and number of children were consistent independent predictors of food handling behaviors. Previous food safety education also was found to have significant effect on food handling practices. TV news and newspapers were considered the most usable sources of food safety information by respondents. The behaviors identified in this study represent ones of particular importance for high-risk populations, like pregnant women. These population characteristics identified in this study could be incorporated in development of food safety educational programs for pregnant women being vulnerable on food-borne illness. Our results could have implications for the design of effective food safety educational efforts. This study indicates the need for continued and improved food safety education and for enforcing systematic food safety education for pregnant women.

The epidemiology of reported food-borne disease (FBD) outbreaks from 2001 to 2008 in Korea nd Japan were compared in this study. The outbreak rate of FBD in Japan was significantly higher although the average umber of patient in each outbreak in Korea was much higher. In both countries, summer was the season when most FBD outbreaks occurred. The comparison study revealed that FBD outbreaks in spring were more frequent in Korea, and outbreaks in winter were more frequent in Japan. Almost half of FBD outbreaks were observed at restaurants in both countries while FBD outbreaks at schools and work-places in Korea were much higher than in Japan. The most frequent cause of bacterial FBDs in Korea was pathogenic Escherichia coli followed by Salmonella species. On the other hand, Campylobacter jejuni was the most frequent source of bacterial FBDs in Japan. Norovirus, which is elated to uncontrolled hand hygiene and involvement of ill food workers, was the main cause of viral FBDs in both countries. In conclusion, there are common epidemiological characteristics as well as several differences in FBD outbreaks of Korea and Japan. These are suggested to be originated from the characteristic of climate, food sources, and life styles in two countries. Establishment of stricter control and surveillance system for FBD outbreaks are required or prevention and reduction of FBD outbreaks in both countries.
