  • 외식산업의 발달과 함께 학교와 기업 등의 단체 급식이 증가하고 있는 오늘날, 관련분야에서는 식중독 예방에 대해 많은 관심을 갖고 연구하고 있다. 우리나라에서는 온도에 따른 세균의 증식속도를 이용하여 식중독지수를 개발하여 식중독 위험에 대한 정보를 제공하고 있는데 그 정보가 식중독 발생상황과는 차이가 있음이 지적되고 있다. 본 연구에서는 최근 3년간($2004{\sim}2006$년)의 일별 식중독 발생과 기상자료를 이용하여 일 최고기온, 습도, 월효과를 설명변수로 하고, 식중독 발생건수를 반응변수로 하는 로그선형모형(Log Linear Model)을 이용하여 식중독 발생의 위험을 예보할 수 있는 사고발생지수를 개발하였다. 개발된 지수와 기존지수를 비교한 결과 개발된 지수가 식중독 발생 상황을 반영함에 있어서 더 나은 설명력이 있음이 나타났다.

  • Background: Foodborne disease outbreaks from various food sources are a major health concern worldwide. Current methods for detection of foodborne pathogens are both expensive and time-consuming. Purpose: This review aims to present the current information available on the use of lateral flow test strips to detect pathogens in food products to enhance food safety. Results: Frequent foodborne disease outbreaks from various food sources have increased the need for rapid and easy methods for routine analysis of foodborne pathogens. Present detection methods for foodborne pathogens require expensive instruments, experts, and long time for sample analysis. Lateral flow test strips have drawn attention in recent years because of their ability to detect analytes quickly and easily. This review focuses on the principle of the lateral flow test, the various formats of lateral flow test strips, recognition elements, labeling tags, and reading instruments. In addition, this review also discusses the future prospects for the lateral flow test strips.

  • The virus isolated from patients with severe pneumonia of unknown etiology in Wuhan City, Hubei province in China was termed SARS-CoV-2 and the World Health Organization (WHO) named the disease caused by this virus as coronavirus disease 2019 (COVID-19). The COVID-19 infection has spread rapidly and become a pandemic. In July 2020, there were 13.25 million infected patients and over 570,000 deaths worldwide, and 13,711 infected patients and 294 deaths were reported in South Korea. Since the primary mode of transmission of COVID-19 is through respiratory droplets, the importance of preventive measures, including social distancing, has become important in daily life. In response to the continuous spread of COVID-19, this study developed three guidelines for preventing COVID-19 for the food service industry including childcare centers, institutional foodservices and restaurants by the integration of the manual of controlling foodborne illness. These are included the COVID-19 prevention action methods for food deliverers, for food service administrator, for foodservice works and for customers. All guidelines were designed for easy understanding using illustrations and have been systematically explained subject wise. Thus, these COVID-19 prevention guidelines can be appropriately applied depending on the specific situation and workplace. In addition, they are worthy as educational materials that contribute to the food safety.

  • This study was conducted to prepare information about foodborne disease outbreaks by year, eating place, etiological agent, area, and type of school lunch program. In the study, the reported data was reviewed, but only the data during recent five years were mainly analyzed because of data shortage.

  • 이 논문에서는 우리나라에서 발생하는 원인균별 식중독 발생건수를 예측하는 방법을 제안한다. 우리나라에서 보고되는 주별 식중독 발생 건수를 원인균로 나누면 자료에 많은 0의 관측값이 포함되어 있으며 식중독 발생 간에 종속성을 가진다. 이 현상을 모형화하기 위해 이 논문에서는 전체 식중독 건수를 자기회귀모형으로 예측하고 원인균별 식중독 발생 확률을 다범주 로짓모형으로 추정한다. 예측된 식중독 건수와 추정된 원인균별 식중독 발생 확률을 곱하여 원인균별 식중독 발생건수를 예측한다. 제안된 방법의 타당성을 확인하기 위해 평균제곱오차와 평균절대편차를 이용하여 제안 방법과 영과잉모형을 비교해 본다.

  • This study was performed to assess microbial contamination of Aronia melanocarpa, blueberry, raspberry, and cranberry sold in several markets. We investigated total aerobic bacteria and detected foodborne bacteria by multiplex PCR from Aronia melanocarpa, blueberry, raspberry, and cranberry. Total aerobic bacteria of each sample showed mean 3.54 log CFU/g for Aronia melanocarpa, mean 1.90 log CFU/g for blueberry, and mean 1.40 log CFU/g for raspberry, but not detected in cranberry. Specially, Aronia melanocarpa contained high total aerobic bacteria contamination among various berries and contamination level reached 4.17 log CFU/g in sample 5. To evaluate the effect of distribution conditions, we also investigated total aerobic bacteria of various berries. Total aerobic bacteria showed mean 2.89 log CFU/g for berries in refrigerated distribution and 1.40 log CFU/g in frozen distribution, but not in dry distribution. For assessment of foodborne bacteria contamination, we conducted PCR with multiplex primers of E. coli O157, S. aureus, B. cereus, V. parahaemolyticus, L. monocytogenes, Y. enterocolitica, Salmonella spp., Shigella spp. Among these foodborne bacteria, B. cereus was amplified in Aronia melanocarpa in sample 4 and blueberry in sample 1, 2, 3, and 5. The result of quantitative analysis of B. cereus contamination showed 4.08 log CFU/g of Aronia melanocarpa in sample 4 and higher contamination rate 4.07 log CFU/g of blueberry in sample 3. These results suggest that strict food safety control in harvest and distribution of various berries is necessary to prevent foodborne disease and improve microbiological safety.

  • 식중독에 의한 사회경제적 손실을 최소화하기 위해서는 식중독과 관련된 경제적 비용 손실을 추정하는 것이 중요하다. 하지만 자료의 부족과 다양한 비용 항목의 존재로 식중독과 관련된 사회경제적 손실비용을 정확하게 추정하기에 어려운 점 있다. 본 연구에서는 국내 식중독 발생에 의한 손실비용을 추정하기에 앞서 국외에서 사용되는 사회경제적 비용항목의 기반 자료 확보를 목적으로 수행되었다. 2009-2019년 국외 식중독과 관련된 사회경제적 손실비용 측정 연구의 사례 조사를 위해 문헌 조사를 실시하였다. 이 연구에서는 사회경제적 손실비용을 크게 의료기간에 방문한 외래/입원환자 및 의료기관에 미방문한 경험환자로 구분하였다. 또한 이들의 직접비용 및 간접비용을 고려하였고, 더 나아가 기업비용 및 행정비용 항목으로 구분하여 조사하였다. 조사 결과 문헌별, 나라별 상이한 비용항목을 사용하여 손실비용을 추정하는 것으로 관찰되었다. 직접의료비의 경우 모든 연구에서 외래 또는 입원진료비를 선정하여 비용을 산출한 것으로 관찰되었기 때문에 나라별 의료서비스의 체제 및 비용에 따라 항목을 선정해야 한다. 직접비의료비의 경우 몇 몇의 연구에서 외래 방문에 소요된 교통비만을 고려하였기 때문에 간병비 고려 여부에 대해서는 더 논의가 필요할 것으로 사료된다. 간접비용 중 조기사망비용, 작업손실비용, 여가손실비용 및 삶의 질 저하/고통비용은 고려하였으나, 병문안 기회비용은 모든 연구에서 고려하지 않았다. 직접의료비와 마찬가지로 행정비용의 경우에도 국가별 정부 예산이 상이하기 때문에 각 나라에 맞는 항목을 고려해야할 것이다. 따라서 이러한 조사 결과를 바탕으로 국내 식중독 발생에 의한 사회경제적 손실비용 분석을 위해 어떠한 비용 항목을 고려해야 할 것인지에 대한 검증절차가 필요할 것이다. 본 연구는 국내 식중독 발생에 의한 사회경제적 손실비용 분석을 위한 기초적인 정보를 제공할 것이다.

  • Pathogenic microbial foodborne disease outbreaks (PMFBDOs) have increased in many countries, the boom in food service establishment is not matched by effective food safety and control. In this study, we investigated the current state and the epidemic aspects of FBDOs in Korea and Japan. In Korea, the average prevalence rate of foodborne disease (FBD) was 15.0 per 100,000 population and cases per outbreak of FBD was 57.0. During the same period in Japan, the prevalence rate showed an average of 24.9, and the cases per outbreak were 16. When both prevalence rate and cases per outbreak were compared, the prevalence rate in Japan was much higher than that in Korea (p<0.01). However, average cases per outbreak of FBD in Japan were much lower than those in Korea (p<0.01). In Korea, outbreaks of FBDs were more common in spring (p<0.01), while in Japan, more frequent in summer and winter (p<0.01). Outbreaks of FBD occurred largely through restaurant and school foods (32.0% and 27.5%) in Korea. In Japan, the proportion of the outbreak cases in the restaurant and home were 23.7% and 12.1%, and cases of unknown causes of FBDs were 48.2%, respectively. Bacteria were the major causes of infection in both countries. The prevalence of PMFBDOs by Salmonella spp. Vibrio parahemolyticus and Staphylococcus aureus were much higher in Korea, while those by Camphylobacter spp. and SRSV were more common in Japan. The causes by virus were more frequent in Japan (13.7%) than in Korea (7.7%). The prevalence of FBDs in Korea and Japan showed characteristic differences, especially in the PMFBDOs due to such factors as geography, climate, culture, diet and food management.
