The purpose of this study was to evaluate the effect of implementing the HACCP system on foodservice establishments. At first, the hygienic conditions were measured by microbiological hazard analyses of the cooking utensils and working areas. In order to solve the detected problems, the HACCP system was implemented, after what was considered a sufficient settlement period following the initial assessment, then microbiological verification was performed again. In relation to the cooking utensils and equipment(kitchen knives, cutting boards, knives for shredding vegetables, refrigerators, baskets, barts, working tables, preparation tables, tungs, dish-clothes and drains) the microbiological inspection on the Total Plate Count, Coliforms, Staphylococcus aureus and Listeria monocytogenes, were conducted with regard to the working areas(working tables, preparation tables, seasoning's shelves, serving tables, drinking water tables, refrigerators, storage rooms and dining tables), the Total Plate Count and Fungi were also examined. According to the microbiological hazard analyses there were many problems, especially with cutting boards, baskets, barts, dish-clothes and sinkballs. However, by introducing the HACCP system, the microbiological hazard levels were able to be controlled and lowered, and the total aerial bacteria in the working areas of the foodservice establishments were detected at levels below 6 CFU/plate.

Indicies of the labor productivity were assessed from 80 industry foodservice erstablishments in terms of meals served per labor hour, labor minutes per meal served, and labor cost per meal served. The labor productivity indicies were also assessed according to variables related to work such as working hours, paryment for the workers, volume of feeding, utilization of foodservice equipment, use of processed foods, and background of employees. The summary of the results was as follows: 1. Manufacturing sector among surveyed industry foodservice showed the highest labor productivity indicies followed by training institute. 2. 28.8% of surveyed establishments used dishwashing machine, while manual dishwashing was used in 71.3% of subjects, equipped rate point was 9.8 out of 20, and disposable dish was used in 30% of subjects. 3. A significant positive relationship was found between the number of meals and the labor procductivity indicies. As the number of meals increased, more meals were served per worker as per labor hour. 4. A significant negative relationship was found between price of meal and the labor productivity didicies. As the price of meal increased, less meals were served per worker as well as per labor hour.

Increased sanitation management of foodservice establishments is required because most of the reported foodborne-disease outbreaks were in the foodservice industry. The purpose of this study was to determine the important control points for good sanitation. In this study, we inspected twenty foodservice establishments in Seoul, Kyunggi, Kyungnam with a self-developed monitoring tool. These foodservice establishments included secondary schools, universities, and industries. Six of them had appointed as the HACCP-certified establishments from the Korea Food and Drug Administration. The inspection was conducted from June to August in 2002. The inspection tool consisted of nine dimensions and sixty-five items. The dimensions were 'personal sanitation', 'supply of raw food', 'food storage', 'handling of raw food and ready-to-eat', 'cleaning and sterilization', 'waste control', 'pest control', and 'control of establishment and equipment' The highest possible score of this inspection tool is 105 points. Statistical data analysis was completed using the SPSS Package(11.0) for descriptive analysis Kruskal-Wallis. The score for the secondary schools (83.6 points) was higher than for the others and number of in compliance item was 50.9 on average. Therefore, we concluded that the secondary schools' sanitation condition was good. The foodservice establishments acquired HACCP certification was 89.7 points, which was significantly higher than that of establishments not applying foodservices in total score. Instituting the HACCP system in a foodservice is very effective for sanitation management. Many out of the compliance observations were found in the dimensions of 'waste control', 'control of establishment and equipment', and 'supply of raw food' 'Clean condition of refrigerator' item was $65\%$ out of the compliance that was the highest percent in this study. 'Notify and observance of heating/reheating temperature' was $45\%$ out of compliance. Items which were over $30\%$ out of compliance were 'sterilization of knifes and chopping boards in cooking', 'education of workers', 'maintain refrigerator temperature blow $5^{\circ}C$', and 'countermeasure of infection workers' In the results, most of the foodservice establishments were poorly managed in temperature control and cross-contamination. The important control points revealed in this study were preventing contamination, cooking temperature compliance, management of raw food and refrigerator. Therefore foodservice establishments should pay attention to education and training about important control points. The systematic sanitation management monitoring tool developed in this study can be effectively applied for conducting self-inspection and improving the sanitary conditions of their own foodservice operations.

This study examined food safety management at preschool establishments in Daegu and Gyeongbuk province, to provide data that can be used for food safety improvements. Field assessments of 60 foodservice establishments were executed from July to October, 2007. Statistical analyses of the data were conducted using the SPSS package program (version 14.0 for windows). The results are summarized as follows: 93.3% of the preschool foodservices were self-operated, and 24.1% of the child care centers and 96.7% of the kindergartens had employed dietitians. According to the averaged food safety evaluation scores the kindergartens (80.73) had a significantly higher score than the child care centers (50.37), and the public centers (85.00) had a significantly higher score than the private centers (54.29). While the average score of facilities that employed dietitian (73.58) was significantly higher than that of facilities that did not employ a dietitian (52.65). In addition, the average score of facilities that served meals in a dining room (80.83) was significantly higher than that of facilities that served meals in a classroom (59.33). The highest scoring food safety items included verifying employee health inspection reports (1.87), utilizing non-municipal water and routinely cleaning and well-maintaining the water storage tank (1.85), and disposing small amounts of leftovers in a vat after serving (1.83). In contrast, the lowest scores were for physical separation of clean areas and unclean areas to prevent cross-contamination (0.52), and physical separation between staff and food material entry areas (0.62). In conclusion, the preschool foodservice evaluated in this study required improvements in food safety management, and many of the child care centers were in need of immediate attention. To improve food safety at these establishments, administrators should implement prerequisite food safety programs.

The purpose of this study was to analyze the microbiological hazards of dried fish (Jwieochae, Ojingeochae and Bugeochae), and to apply pretreatment methods to increase the safety of cooked dried fish within foodservice establishments. Microbiological inspections were conducted on Total Plate Count, Coliforms, E. coli, E. coli O157:H7, Staphylococcus aureus, Salmonella spp. and Listeria monocytogenes. The study results are summarized as follows. According to the Hazard analysis, there are many problems showing high numbers in terms of Total Plate Count and Coliforms, which were both well over acceptable standard levels. E. coli and Staphylococcus aureus were detected at certain foodservice establishments, while E. coli O157:H7, Salmonella spp. and Listeria monocytogenes were not detected at all. By applying various pretreatment methods, such as washing, blanching, pan frying and microwave heating, the levels of microbiological hazards were able to be controlled and lowered. Blanching was the most effective method, followed by panfrying, microwave heating and washing. The Total Plate Counts gradually decreased with increasing number of times washed and seconds panfried. From these results, it is concluded that to guarantee food safety, cooked dried fish raw materials should be kept hygienically and appropriate pretreatment methods applied before cooking.

The rapid increase in food borne illness outbreaks in Korea has been one of the major threats to the Nation's Health. Foodservice establishments have been identified as the major place for these outbreaks, mainly due to the lack of sanitary management and sanitary facility management practices. The purposes of the study were to develop hospital foodservice facility evaluation tools, based on the general HACCP-based standards and guidelines, for hospital food service establishments, to ensure the safety of these foodservices and to reduce the risk of food home illness. The scope of this study included: 1) an assessment of the current foodservice sanitation practices and managements for 6 general hospitals, with more than 400 beds, and 3 general hospitals, with less than 400 beds; 2) the development of foodservice establishments sanitation evaluation tools and sanitation standards, based on the HACCP system. The survey data showed varied results between the hospitals surveyed. Most of the hospital foodservice operations had many problems with ventilation and the plumbing. The total dimensional mean scores for the hospitals with more than 400 beds and less than 400 beds were 31.5 and 27.0, respectively. The highest dimension scores were for the water supply facility and lighting, with the lowest for insect and rodent control and toxic materials management. The levels of the mean scores were very low, especially for the general hospitals with less than 400 beds. These low mean scores may have arisen from critical problems within the hospital foodservice operations. The most needed facility management items for improvement were: storage shelf should be spaced 6 inches from the floor and walls, the use of three compartment sinks, utility sinks and cleaning facilities, with a floor drain for cleaning mops or liquid wastes, a ventilation hood designed to prevent dripping onto food, cooking facilities should be disassembled for washing and sanitizing, a separated hand washing sink and a sanitized food board for each area should be provided, all toxic material must have warning labels attached, and be stored in an area away from food preparation under padlock. The evaluation tool consisted of 14 dimensions, with 65 check-off items. The results of this study will provide basic facilities' guidelines to regulators, or foodservice industry personnel, wishing to build, or expend, and establish an efficient flow of food. As a result, food borne illnesses will be effectively prevented, and the Nation's health will be promoted for the development of their own sanitation standards, with a checklist for the safe production of foods.

This study was examined the preferred temperature and salinity of soup in various demographic groups in order to establish the desirable serving renditions of soup for customers' satisfaction and health. Temperature and salinity were measured in August and November in order to determine the seasonal variation in preference using a digital salinity-temperature measuring device. Four demographic groups totaling 530 were from foodservice establishments in elementary schools(ES: male 68/female 59), middle-high schools(MHS: 62/69), universities(UNIV: 72/67) and companies(COM: 69/64) in Seoul. Various thin or thick soups which are typically served in foodservice establishments were served hot(below $90^{\circ}C$) and warm(below $40^{\circ}C$) in a 50mL portion: salty(1.2%) and less salty(0.4%) at $55{\pm}2^{\circ}C$. The preferred salinities and temperatures of the soups were found to be 0.74%, 0.82%, 0.64% and 0.67% and $49.65^{\circ}C$, $54.24^{\circ}C$, $57.56^{\circ}C$, $58.81^{\circ}C$ for the ES, MHS, UNIV and COM groups, respectively. The preferred temperatures of the soups were increased depending on the age, so the positive correlation was shown between temperature and age. However the preferred salinities of soups were not effected. There was no consistent tendency between men and women in temperature. For salinity, men preferred $0.04{\sim}0.12%$ higher than women in the ES, MHS and UNIV groups. There is no consistent tendency between thin and thick soup in temperature. All groups preferred higher salinity in the thick soup than in the thin soup. Most of the customers preferred a higher temperature and higher salinity in November than in August.
