The main problems contributing to food poisoning outbreaks in institutional settings and a home were reviewed and analyzed through the epidemiological investigations of food poisoning. The major documented factors included improper holding temperatures, inadequate cooking, poor personal hygiene, cross-contamination and contaminated equipment, food from unsafe sources, failure to follow food hygiene policies, and lack of education, training, monitoring and superivision. Usually more than one factor contributed to the development of an outbreak. (1) Use of improper holding temperatures was the single most important factor contributing to food poisoning. They included improper cooling, allowing a laps of time (12 hours or more) between preparing food and eating it, improper hot holding, and inadequate or improper thawing. Food thermometers were not used in most of the instances. (2) In inadequate cooking, the core temperature of food during and after cooking had not been measured, and routine monitoring was limited to recording the temperature of plated meals. Compared with conventional methods of cooking, microwave ovens did not protect against food poisoning as effectively. Centralized food preparation potentially increased the risk of food poisoning outbreaks. (3) Poor personal hygiene both at the individual level (improper handwashing and lack of proper hygienic practices) and at the institutional level (poor general sanitization) increased the risk of transmission. Person to person transmission of enteric pathogens through direct contact and via fomites has been noted in several instances. (4) Obtaining food from unsafe sources was a risk factor in outbreaks of food poisoning. Food risks were high when food was grown or harvested from contaminated areas. Possibilities included contamination in the field, in transport, at the retail site, or at the time it was prepared for serving. (5) Cross-contamination and inadequate cleaning/handling of equipment became potential vehicles of food poisoning. Failure to separate cooked food from raw food was also a risk factor. (6) Failure to follow food hygiene policies also provided opportunities for outbreaks of food poisoning. It included improper hygienic practices during food preparation, neglect of personnel policies (involvement of symptomatic workers in food preparation), poor results on routine inspections, and disregarding the results and recommendations of an inspection. (7) Lack of formal and in-service education, training, monitoring, and supervision of food handlers or supervisors were critical and perhaps neglected elements in occurrences of food poisoning.

Objectives: This study was conducted to identify the awareness and practice of reducing sugar in school meals and the status of nutrition education regarding sugar reduction. Methods: An online survey was conducted on 101 nutrition teachers (dietitians) working at elementary, middle, and high schools in Daegu. Results: School nutrition teachers in Daegu recognized the need for efforts to reduce the sugar intake in the Korean diet, and it was found that elementary nutrition teachers were more aware of the implementation of the sugar reduction policy at the national level than middle and high school nutrition teachers (P = 0.002). Among the policies to reduce sugar intake at the national level, there was a high need for the promotion of self-control and limiting the sales of food with high sugar content in schools and their vicinity. The degree of practice for reducing sugar in school meals was found to be higher in the preparation, purchase, and cooking stage compared to the serving stage (P < 0.05). There was a high need for changing the preferences of the subjects for a sweet taste as a means of reducing the sugar in school meals. Thirty-six percent of nutrition teachers conducted sugar reduction education, and sending out school newsletters was the highest type of nutrition education at 80.6%. Conclusions: To effectively promote reduced sugar intake in school meals, it is necessary to change the preference of the subjects for sweetness and to conduct continuous education that can improve the awareness of people for reducing their sugar intake. For this, it is necessary to set aside time for nutrition education and to prepare an institutional framework for providing this education.

This study investigated the eating habits of elementary school children and their perceptions related to traditional Korean foods, based on the health belief model. The subjects were fifth grade elementary school children (274 boys and 274 girls) in eight Korean cities. The results were as follows: The children ate almost three meals per day and were grateful for their meals. However, they irregularly consumed meals and snacks. They tended to eat heartily and did not eat foods that they had not yet eaten. Their meals were based on rice and they have eaten kimchi and vegetables at almost every meal. However, they had undesirable habits in eating other foods, such as fruits, fish, soybeans, and sweet foods. They did not sensitively or seriously perceive their eating habits in relation to their health. They perceived that it was very good for their nutrition, health, and tastes to eat traditional Korean foods, and they had pride in traditional Korean foods and eating style. Although they expressed some difficulty regarding availability and preparation of traditional Korean foods, they hardly felt difficulty in eating them. They had high dietary self-efficacy with regard to eating these foods, except for two items of self-regulation. Their eating habits showed positive correlation with dietary self-efficacy, perceived susceptibility, and perceived benefit. In conclusion, eating habits of elementary school children in relation to traditional Korean foods are not desirable, but not serious. They did not sensitively or seriously perceive their eating habits in relation to their health. However, they perceived that it was very good for their nutrition and health to eat traditional Korean foods, did not have a high level of difficulty in eating them, and had high dietary self-efficacy with regard to eating them. Therefore, we suggest that children should be exposed to various traditional Korean foods, along with education about them, in order to enhance their concern and motivation to eat them.

The purpose of this study was to investigate the perception of foodservice managers in childcare centers and kindergartens for identifying the vulnerable areas of safety management. The foodservice managers in 1,144 of nationwide childcare centers and kindergartens were surveyed from May to October 2007 to answer a total 72 questions in areas of general characteristics, actual practice of foodservice management and safety management perception. Meals were served in 97.7% of surveyed facilities and 91.0% among them were self-operated. The hiring rate (27.8%) of dietitians in childcare centers was significantly lower than the rate (82.0%) of kindergartens. The needs of dietitian employment between childcare centers and kindergartens differed as 44.9% and 87.5%, respectively. In knowledge on food-borne illnesses, they have the wrong information in the field of season for frequent outbreak, major pathogens and foods causing food-borne illnesses. The food-borne illnesses (36.2%) were indicated as the major problem in foodservice facilities and the degree of risk exposure was considered as safe (70.1%). More than 70% of both facilities answered as sanitary in the status of personal hygiene. Only 38.0% recognized the Facility and Equipment Standard in the Childcare Law and Early Childhood Education Law. In preparation of meals and management of cooking processes, kindergarten scored significantly high compared to childcare centers (p < 0.05 or p < 0.01) while the necessity of standards was not different in both facilities. Among managers surveyed, 28.8% had taken food safety education from professional institutions and more than 80% in both facilities indicated the need of professional educations. These results suggest that it is necessary for the systematic sanitary education of foodservice managers by developing the sanitary management standard as well as the amendment of laws related foodservice in childcare centers and kindergartens.

The purposes of the study were to establish HACCP-based standards and guidelines for conducting a plan review to build, or renovate, hospital food service establishments, and ensure the safety of foodservice and reduce the risk of food borne illness. The scope of the study included suggestion for the planning of hospital foodservice facilities: layout, design, equipment and modeling. The results of this study can be summarized as follows: 1) The development of a foodservice facility plan based on the results of a survey, literature reviews and the results of interviews with foodservice managers from 9 general hospitals. This was composed of operational policies in foodservices, layout characteristics, space allocation, selection, design, specification standards for equipment and the construction principles of foodservice facilities. 2) Two foodservice facility models were developed, one for general hospitals with 900 beds (2,000 patients and 2,500 employee meals per day) and the other for general hospitals with 300 beds (600 patients and 650 employees meals per day). 3) The suggested kitchen space requirements for the foodservice facility models were 341.2 ㎡ (W 17,100mm x L 23,700mm) and 998.8㎡ (W 35,600mm x L 32,800mm) for the 300 and 900 beds hospitals, respectively, with both designs being rectangular. The space requirements for the equipment, in relation to the total operational area, in terms of ratios were 1:3.5 and 1:3.8 for the 300 and 900 beds hospitals, respectively. The recommended space allowances per bed for the developed foodservice facility models were 1.15 ㎡ and 1.11 ㎡ for the 300 and 900 beds hospitals, respectively, which were increased by more than 30% compared to those suggested in the precedent study, and considered appropriate for the implementation of the HACCP system. 4) The hospital foodservice facilities plans and models were developed based on the general sanitation standards, guidelines and the HACCP system, and included foodservice facility layout, product flow, physical separation between contaminated and sanitary areas, foodservice facility specifications with a 1/300 scale for a 300 bed, and a 1/400 scale for a 900 beds blueprint. 5) The main features of the developed foodservice facility plans and models were; physical separation between contaminated and sanitary areas to prevent cross contamination, product flow in one direction from the arrival of the raw material to the finished product, and separation of different work areas and the process of receiving & preparation of products, refrigeration & storage, cooking, assembly, cleaning & disinfection, employee areas and janitorial facilities. The proposed models from this study were presented as examples for those wanting to build, or renovate, their facility for the production of foods.

The purpose of this study was to investigate food habits of boy students and to know the difference in food habits between boy and girl students. A previous study had been conducted to girl students in 1998 and this study was carried to boy students in Oct. 2000 using the questionnaires. The subjects were 783 boy students in middle school, high school and university students living in Jeonbuk region. The average score of food habits was $4.09{\pm}1.72$ out of a possible 10(middle school students were $4.96{\pm}1.85$, high school students were $4.17{\pm}1.61$ and university students were $3.15{\pm}1.70$). The average is similar $4.11{\pm}1.63$ to girl students in 1998. The correlation coefficient between the score of food habits and standard of living, present residence, taking nutritional supplements, and sort of school was positive. As a staple food, cooked rice was preferred 95.9% of subjects and this result is similar to girl students of previous study. The most preferred side-dishes was different between girl and boy students. Boy students liked stew the best, but girl students liked Kimchi the best. The most preferred snacks was fruits and fruit juice. The portion of eating cooked rice in boy students (87.8%) was decreased than girl students(90.6%) at breakfast. The main meal to have soup & stew was supper and the most delicious meal was also supper, but primary meal skipped was breakfast. The reasons for skipping breakfast were lack of time(38.7%) and no appetite(17.6%), skipping lunch was missing a time to eat(8.4%), and skipping supper was no appetite(10.5%). Substitution food on no preparation of lunch basket was difference between middle and high school students and university students. Middle and high school students ate noodles and university student ate cooked rice. The preference of snack was that chicken(20.3%) was the best. The time of eating snacks was that anytime(38.6%) was the first, after supper(13.7%) was next. In order to improve the nutritional status of boy students, they must establish good food habits by eating three regular meals per day and balancing their diet. Especially university student must build their regular life style, so they would have three regular meals.

The purpose of this study was to find out the common characteristics of eating behaviors of the long-lived elderly in order to offer the basic data for establishing dietary guidelines for a long and healthy life for the general population. The subjects were three-hundred elderly people over age 85 living in Kyungpook Sung-ju who have no problems in daily living. The general characteristics, nutrition knowledge and attitudes, meal patterns, and food preferences of the subjects were surveyed by individual intervies. The levels of the nutrition knowledge of the subjects were very low(average score ; 4.3) and the correlation coefficient between their nutrition knowledge and attitude score was also low(r=0.323, p=0.000). Most of the subjects(93%) had a regular meal pattern consuming three meals a day. The major staple food was rice mixed with other grains(75%) and the number of side dishes was mostly under four(99%). A majority(73%) had no habit of overeating and 51% of the subjects were taking snacks besides regular meals. Thirty one percent of the subjects had drinking habits and 80% of the drinking subjects had over 40 years of drinking history. The most common frequencies for intakes of various food groups were ; more than once a day(95%) for vegetables ; 2∼3 times a week(74%) for green and orange color vegetables ; 2∼3 times a week(72%) for fruits ; once a day(70%) for fish, eggs and legumes ; 2∼3 times a week(49%) for milk ; 2∼3 times a week(72%) for fruits ; once a day(70%) for fish, eggs and legumes ; 2-3 times a week(49%) for milk ; 2-3 times a week(85%) for seaweeds and 2-3 times a week(81%) for foods cooked with oil. The most preferred foods by the subjects were white rice(staple foods), soybean paste soup(soups), beef and eggs(meats and eggs), yellow croaker and hair tail(fish and shellfish), yoghurt(milk and milk products), all vegetables except carrot(vegetables), and watermelon(fruits). The popular food preparation methods included mixing with seasonings and the most preferred taste was sweet. The results showed that the eating pattern of long-lived elderly was characterized by regularity, simplicity, and no overeating.

Objectives: The occurrence of norovirus food poisoning in South Korea has been reported since 2003. This study was performed to investigate the characteristics of norovirus food poisoning outbreaks in Korea from 2006 to 2015 and to analyze the relationship between these outbreaks and climate factors. Methods: Data on norovirus food poisoning outbreaks were obtained from the Korea Ministry of Food and Drug Safety. Data on climate factors were obtained from the Korea Meteorological Administration. Frequency analysis and Pearson's correlation analysis were adopted for this study. Results: During the study period, norovirus was the greatest contributing factor of food poisoning outbreaks. Approximately half of the outbreaks of norovirus food poisoning occurred in winter. Average temperature, highest and lowest temperatures, precipitation, number of days with rainfall, and humidity all had a significant negative correlation with monthly number of outbreaks of norovirus food poisoning (p<0.05). Among these, the lowest and average temperature showed higher correlation coefficients. However, the sum of the outbreaks in spring and autumn was similar to that of winter, and more than one-third occurred in group meal-service settings, including school lunches. This was strongly assumed as the use of norovirus-contaminated groundwater for preparation of meals in some settings. Conclusion: The cold and dry of the winter season in Korea may assist the transmission of norovirus. Also, the use of groundwater in group meal service is suspected of inducing a larger scale of norovirus food poisoning. Both health authorities and community-based prevention and control measures are required to respond to these complex etiological outbreaks.

In this survey, we investigated the way of thinking about meal management of housewives including the sincerity to meal preparation, the eating practices and cronic degenerative diseases related dietary behaviors, and studied the effects of above factors on the real food intakes. We also investigated the trends of health-foods and nutrient supplements usage. The results obtained from 506 housewives in Seoul were summarized as follows. Although our subjects prepared their meals habitually without special concern, they did not prefer the use of convenient foods. The food prefrence of housewivess who had more child and refered higher life status was similar with other family members. The dietary attitudes were good in large family, the higher income and the more child group. The highly educated group skipped breakfast more frequently. The mealmanagers with better education career and good living status considered for the restriction of salty foods, sweet foods, animal fats and pungent foods, and for the nutritionally balanced diet. The high income group showed great concerns about weight gain at meal times. The nutritional qualities expressed by the frequency of food group intakes were high in the better educated and living status groups, and their eating frequencies of animal protein foods and calcium sources were significantly high. Mealmanagers who had no job intaked vegetable oils through frying foods frequently. The use of health-foods and nutrient supplements was influenced by age, educational and economic level and self-estimated living status, but the trends in prevalence of both were not consistent. Health-foods were prefered by the groups of high educational career, affluent income and advanced living status, and low educational career, low income and low living status groups favored the nutrient supplements. The restrictive intake of animal fat and the use of health-food were positively correlated, which seemed that the subjects used health-foods as supplements in compensation for nutritional unbalance caused by the avoidance of animal protein foods.
