This mini review focuses on foodborne illnesses and outbreaks caused by food-producing animals because statistical information of the foodborne illnesses is important in human health and food industry. Contaminated food results in 600 million cases of foodborne diseases and 420,000 deaths worldwide every year. The world population is currently 7.8 billion, and 56 million people die every year; of these, every year, 7.69% of people experience foodborne diseases, and 7.5% of annual deaths (56 million deaths) was died by foodborne illness in the world. A majority of such patients are affected by norovirus and Campylobacter. Listeria monocytogenes is the most fatal. In the United States, except for those caused by Campylobacter, the number of foodborne diseases did not decrease between 1997 and 2017, and cases caused by Toxoplasma gondii are still being reported (9 cases in 2017). The percentage of foodborne illnesses caused by food-producing animals was 10.4%-14.1% between 1999 and 2017 in the United States. In Europe, foodborne illnesses affect 23 million people every year and cause approximately 5,000 deaths. Europe has more Campylobacter- and Salmonella-related cases than in other countries. In Australia, the highest number of cases are due to Campylobacter, followed by Salmonella. In Korea, Escherichia coli followed by norovirus. Campylobacter- and Clostridium perfringens-related cases have been reported in Japan as well. This review suggests that Campylobacter, Salmonella, L. monocytogenes, and E. coli, which are usually isolated from animal-source food products are associated with a high risk of foodborne illnesses.

The purpose of this study was to investigate middle school students` perceptions on foodborne illness prevention in relation to their personal hygiene practices. The survey was administered in July, 2007 at one middle school, with a total of 390 students participating. The self-completed questionnaire consisted of several questions regarding the students` awareness of foodborne illness, perceptions of foodborne illness prevention, and personal hygiene practices. T-tests were used to identify the differences in their perceptions of foodborne illness prevention based on gender and Chi square tests were used to identify the relationships between their perceptions of foodborne illness prevention and personal hygiene practices. Eight percent of the respondents experienced foodborne illness at least once a year and 33.8% of them have stopped eating certain foods due to anxiety towards foodborne illness. The students perceived school foods (26.0%) and street foods(17.9%) as the main sources of foodborne illness, and dairy products(20.0%) and fresh fish (19.7%) were considered foods having the greatest potential for causing foodborne illness. Many students were aware of Escherichia coli O157(43.1%) and Hepatitis A(23.3%), but only a few recognized Clostridium botulinum(4.1%) and Salmonella(7.9%), even though these are major foodborne illness-causing pathogens. The students considered foodborne illness prevention very important(mean = 4.33); also, the results showed that many washed their hands 3-4 times (34.1%) and 5-6 times(29.2%) per day. Hand washing frequency was significantly related to the perceived importance of personal hygiene practice as well as to education on safety and sanitation. However, the students` perception on the importance of personal hygiene practices were not significantly different based on having received safety and sanitation education. Ultimately, these results will be used to develop guidelines for effective education on safety and sanitation.

Food safety is increasingly becoming an important public health issue, as foodborne diseases present a widespread and growing public health problem in both developed and developing countries. The rapid and precise monitoring and detection of foodborne pathogens are some of the most effective ways to control and prevent human foodborne infections. Traditional microbiological detection and identification methods for foodborne pathogens are well known to be time consuming and laborious as they are increasingly being perceived as insufficient to meet the demands of rapid food testing. Recently, various kinds of rapid detection, identification, and monitoring methods have been developed for foodborne pathogens, including nucleic-acid-based methods, immunological methods, and biosensor-based methods, etc. This article reviews the principles, characteristics, and applications of recent rapid detection methods for foodborne pathogens.

Background: Foodborne pathogens are a growing concern with respect to human illnesses and death. There is an increasing demand for improvements in global food safety. However, it is a challenge to detect and identify these harmful organisms in a rapid, responsive, suitable, and effective way. Results: Rapid developments in biosensor designs have contributed to the detection of foodborne pathogens and other microorganisms. Biosensors can automate this process and have the potential to enable fast analyses that are cost and time-effective. Various biosensor techniques are available that can identify foodborne pathogens and other health hazards. Conclusions: In this review, biosensor technology is briefly discussed, followed by a summary of foodborne pathogen detection using various transduction systems that exhibit specificity for particular foodborne pathogens. In addition, the recent application of biosensor technology to detect pesticides and heavy metals is briefly addressed.

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.

The purpose of this study was to investigate differences in the perception and attitudes of middle school students toward food safety between those who possess high behavioral intentions to prevent contracting a foodborne illness and those who do not. The survey collected 871 usable data from several middle schools in Seoul, Korea in July 2007. Using six behavioral intention measurement items, a two-step cluster analysis approach was conducted resulting in a strong intention group and a weak intention group. Perception and attitudes toward foods safety were different between the two groups. Students with strong behavioral intentions to prevent foodborne illness tended to possess a stronger perception and attitude toward various food safety issues. Students with strong intentions were more certain of consumer's right to purchase safe foods, more concerned about foodborne illness and food safety, believed that the government should put more efforts toward establishing a safe food chain, possess more distrust for food suppliers, were more aware of specific foodborne illness pathogens, had more food safety education/training, and washed their hands more frequently than those with less strong intentions. No significant differences were found between the groups but,overall, chemical residues and food additives were perceived as more harmful and more serious food safety issues than those of foodborne illness pathogens despite that microorganisms are the main cause of foodborne illness outbreaks in schools. Participants seemed to underestimate the importance of temperature control for preventing foodborne outbreaks. Several implications and suggestions on how to improve the behavioral intentions of middle school students to prevent possible foodborne illness were provided.

Food safety is the most important global health issue due to foodborne pathogens after consumption of contaminated food. Foodborne bacteria such as Escherichia coli, Salmonella enterica, Staphylococcus aureus, Campylobacter spp., Bacillus cereus, Vibrio spp., Yersinia enterocolitica and Clostridium perfringens are leading causes of the majority of foodborne illnesses and deaths. These foodborne pathogens often come from the livestock feces, thus, we analyzed fecal microbial communities of three different livestock species to investigate the prevalence of foodborne pathogens in livestock feces using metagenomics analysis. Our data showed that alpha diversities of microbial communities were different according to livestock species. The microbial diversity of cattle feces was higher than that of chicken or pig feces. Moreover, microbial communities were significantly different among these three livestock species (cattle, chicken, and pig). At the genus level, Staphylococcus and Clostridium were found in all livestock feces, with chicken feces having higher relative abundances of Staphylococcus and Clostridium than cattle and pig feces. Genera Bacillus, Campylobacter, and Vibrio were detected in cattle feces. Chicken samples contained Bacillus, Listeria, and Salmonella with low relative abundance. Other genera such as Corynebacterium, Streptococcus, Neisseria, Helicobacter, Enterobacter, Klebsiella, and Pseudomonas known to be opportunistic pathogens were also detected in cattle, chicken, and pig feces. Results of this study might be useful for controlling the spread of foodborne pathogens in farm environments known to provide natural sources of these microorganisms.

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.
