A survey on sanitary management at 98 food service institutions located in Jeollabuk-Do were conducted. Food service institutions included 13 hospitals, 38 schools, 40 enterprises, and 7 others. The sterilization in boiling water was used for disinfection of tableware, spoon and chopsticks, and dish towel. Cooking kit, refrigerator, chopping board, and knife were sterilized with disinfectant. Frequency of sanitary training program on employees was 56.1% for 1 time/month, 12.2% for 2-3 times/month, and 11.3% for 1 time/week. Preparing ratio of defrosting, warehouse and rest room, and washing and sterilization diary were 73.8, 60.5, and 54.5%, respectively. However, checking ratio of environments (9.5%), personal sanitation (10.8%), and sanitary training program diary(8.4%) were low. Major obstacle factors on the introduction of Hazard analysis critical control point (HACCP) system into food service institutions were lack of equipment and facilities (54.1%) and lack of understanding and data on HACCP system (17.3%). Therefore, in order to reduce the outbreak of food-borne diseases increasing frequency, we estimated that the introduction of sanitary management system and the conversion of dietician' perception on sanitary managements in food service institutions were needed.

This survey was conducted to assess the consumer perceptions of food-related hazard in 500 housewives from all over Korea. The subjects were selected by stratified random sampling method. The survey was performed using structured questionnaire through telephone interview by skilled interviewers. The results showed that 34.6% of the respondents felt secure and were not concerned about food safety, and 65.4% were concerned about food safety. Logistic regression analysis showed that the increasing concern on food brands, food additives (such as food preservatives and artificial color), and imported foodstuffs indicated the current increasing concern on food safety. Other related factors indicating the increasing concern on food safety were education level and care for children's health. The respondents who cared about food safety expressed a high degree of concern on processed foodstuffs such as commercial boxed lunch (93.3%), imported foods (92.7%), fastfoods (89.9%), processed meat products (88.7%), dining out (85.6%), cannery and frozen foods (83.5%), and instant foods (82.0%). The lowest degree of concern was on rice. All the respondents perceived that residues of chemical substances such as pesticides and food additives, and endocrine disrupters were the most potential food risk factors, followed by food-borne pathogens, and GMOs (Genetically Modified Organisms). However, these results were not consistent with scientific judgment. Therefore, more education and information were needed for consumers' awareness of facts and myths about food safety. In addition, the results showed that consumers put lower trust in food products information such as food labels, cultivation methods (organic or not), quality labels, and the place of origin. Nevertheless, the respondents expressed their desire to overcome alienation, and recognized the importance of knowing of the origin or the producers of food. They identified that people who need to take extreme precautions on food contamination were the producers, government officials, food companies, consumers, the consumer's association, and marketers, arranged in the order of highest to lowest. They also believed that the production stage of agriculture was the most important step for improving the level of food safety Therefore, the results indicated that there is a need to introduce safety systems in the production of agricultural products, as follows: Good Agricultural Practice (GAP), Hazard Analysis and Critical Control Point (HACCP), and Traceability System (75).

The tempering system which is developed by this research which sees energy curtailment and from the environmental side which is essential for in hazard analysis critical control point. The tempering system with development experimented frozen pork and fish. As test result, frozen pork region was not thawed occurred plentifully. Like this the actual condition, the case of frozen fish is grind and the bulk and density uniformly was formed, the pork the density was dense and was thought with the fact that the temperature difference change is big. Also after tempering from measurement location center the temperature appeared substitutionally with the low-end thing. This central part of the frozene region is thought the impedance change appears few. To hereafter respects an impedance change is thought that has the necessity which will change the structure of tempering system.
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.
A sanitary quality of a university foodservice establishment was assessed in terms of time and temperature, pH and Aw, and microbiological evaluation. Critical control points during various phases in product flow of fried fish cake soup were identified using hazard analysis concept. The results are summarized as follows : 1) Time and temperature data indicated that phases of holding ingredients at room temperature after cooking, and hot - holding of soup before assembly were critical. 2) pH and Aw values were in favorable for microbial growth. 3) Microbiological data indicated that microbial quality of ingredients was in poor condition. A holding practice of cooked ingredients at room temperature might provide the chance for microbial contamination and multiplication. Hot - holding time and temperature of soup should be strictly controlled to assure the food safety, since the microbial quality of serving food can be directly influenced by the hot - holding temperature of soup. 4) Microbiological test results for food containers, equipments, working surfaces, and supplies indicated that sanitary conditions of earthenware, gloves, wiping cloths and cutting board should be improved promptly. 5) Critical control points identified were : ingredients, pre - preparation, post - preparation, and holding before assembly and service. 6) Guidelines for the effective quality control program for this operation were suggested.
The purpose of this study was to identify the hazard analysis critical control point on food production and transportation flow, applied to home-delivered meals for the elderly. To carry out this study, 1) pan-fried oak mushroom and meat, soy sauce glazed hair tail, and roasted dodok were selected as high nutrient and preferred foods for the elderly and 2) time, temperature, and microbiological quality(standard plate count, coliform, Salmonella spp, Vibrio parahaemolyticus, Staphylococcus spp., Escherichia coli O157:H7, and Listeria monocytogenes) were measured at various phases of the home-delivered meal production and its transportation flows. The results of this experiments are as follows: The temperature measured at cooling phases during the home-delivered meal production flows was 19.2 ∼ 20.0$^{\circ}C$ for the pan- fried oak mushroom and meat and the roasted dodok and was 24.0 ∼ 25.2$^{\circ}C$ for the soy sauce glazed hair tail. These temperature were in the potentially dangerous zone. Microbiological analysis showed that S. spp. was higher in the raw ingredients, including oak mushroom, hair tail, radish, and dodok, than the standard limit. SPC was lower than the standard limit from cooking to transportation phase, but SPC increased significantly during the cooling and packaging phase. The level of coliform detected was far lower than the standard limit and was not detected at all during the transportation phase. Few S. spp. was detected in the pan-fried oak mushroom and meat, but was found in above standards limit during the wrap packaging phase in the soy sauce glazed hair tail and roasted dodok. The level decreased rapidly during the holding and transportation phase. Sal. spp., V. parahaemolyticus, S. spp., E. coli O157:H7, and L. monocytogenes were not detected. For the pan-fried oak mushroom and meat, the critical control points were during the purchasing and receiving of raw ingredients, cooling, and packaging phases. For the soy sauce glazed hair tail and roasted dodok, the critical control points were during the purchasing and receiving of raw ingredients, preparation, cooling, and packaging phases.
This study was focused on the sanitary analysis of hazard factors and the establishment of critical control points on hamburger by the microbiological investigation. The degree of microorganic pollution on the ingredients and equipments for hamburger manufacturing and the variation of microorganisms at storage time and temperatures were investigated. The magnitudes of total aerobic bacteria In hamburger were highly detected to be in the order of resting placed in expressway > convenience stores > fast food stores, and coliforms were lowly detected as convenience stores > fast food stores > resting places in expressway. In investigation of basic ingredients, the degree of microorganic pollution showed highly on patty. cabbage and cucumber. In investigated result of mocroorganic distribution at the various phases in hamburger manufacturing, total aerobic bacteria counts were detected over 5.5$\times$10$^2$ CFU/g, and coliforms counts were detected over 2.0$\times$10$^2$ CFU/g. In investigated result of microorganic distribution on the instruments and equipments for hamburger manugacturing, total aerobic bacteria counts were detected over 10$\^$5/ CFU/100cm2 and coliforms counts were detected over 10$^2$CFU/100㎠. Staphylococcus aureus was detected at wagon and refrigerator. Salmonella spp. was detected at grinder and Vibrio parahaemolyticus was not detected. At various storage temperatures, total aerobic bacteria counts insreased 3.0$\times$10$^3$ CFU/g to 7.0$\times$10$^4$ CFU/g, 4.2$\times$10$\^$7/ CFU/g and 8.1$\times$10$\^$8/ CFU/g at 10$\^{C}$, 20$\^{C}$, 30$\^{C}$ after 48 hours respectively. coliform counts also increased 4.5$\times$10$^2$ CFU/g to 2.2$\times$10$^3$ CFU/g, 5.4$\times$10$\^$5/ CFU/g, 4.5$\times$10$\^$6/ CFU/g at 10$\^{C}$, 20$\^{C}$, 30$\^{C}$ after 48 hours respectively. The establishment of critical control point CCP was divided into CCP1 and CCP2 by the removing level of hazard factor, and then CCP1 was established on basic ingredients, and CCP2 was established on the phases of mixing, pouring, packaging, transporting and preserving.
In Korea, the school foodservice program has been expanding rapidly in recent years, partly as a result of increased government support. With the growth in the number of schools offering foodservice programs, food safety and sanitation concerns have been increasing. To assist with program improvement, a situation analysis was carried out, with the focus on equipment and sanitary management of school foodservice programs under flour different management systems. A questionnaire was mailed to the foodservice directors of 234 randomly selected schools chi[h included elementary, middle and high schools at the national level. Among them, one hundred and sixty-five responses reasonably completed were used for the analysis. This study classified each school's foodservice management into one of four types : independent-conventional, independent-commissary, contract-conventional, and contract-delivery. The results show that the monitoring of employees' health and personal hygiene, and employees' sanitary education was well conducted, but that the sanitary education of the voluntary parent workers was largely ignored. Eighty-six percent of the schools had their drinking water tested for sanitation, and the results showed that more effort is needed in careful management of drinking water in order to prevent foodborne illnesses and bacillary dysentery. In general, contract management showed lower scores in foodservice equipment and their efficiency, compared with independent management. A relatively high number of schools on the contract-delivery management system employed nurses and leachers instead of dietitians and foodservice directors. The adoption of the HACCP (Hazard Analysis Critical Control Point) system was lowest in contract-conventional and contract-delivery management systems, and highest in elementary schools using the independent-conventional system.
The purposes of this study were to develop Hazard Analysis Critical Control Point-based standardized recipe applicable to cook/chilled Broiled Spanish Mackerel in school foodservice operations and to establish reasonable shelf-life limits by assessing food quality during chilled storage period of 5 days. HACCP for the production of menu items was identified in simulation study. At each critical control point, time-temperature profile was recorded and microbiological analysis was done. Also chemical analyses and sensory evaluation were conducted for 5 days of chilled storage. The results of time-temperature measurement of Broiled Spanish Mackerel by each production phase showed satisfactory condition that met the standards. Broiled Spanish Mackerel showed excellent microbiological quality from raw ingredient phase ($TPC:2.58{\pm}0.12\;Log\;CFU/g$) to holding phase ($TPC:2.70{\pm}0.42\;Log\;CFU/g$). Coliform (0.84 Log MPN/g) and fecal coliform (0.84 Log MPN/g) were detected from marinating phase ($TPC:3.82{\pm}0.52\;Log\;CFU/g$). After heating, only few mesophiles were detected ($TPC:1.83{\pm}0.49\;Log\;CFU/g$). No psychrophiles, coliforms and fecal coliforms were detected. In the phases after rapid chilling, during chilled storage and after reheating and distribution, almost none of the above microbes were detected. Salmonella and Listeria monocytogenes were not detected in all production phases. The pH immediately after cooking was 6.65 and then increased significantly to 6.81 on the third day of chilled storage (p<0.001). Acid value did not show significant changes while total volatile based nitrogen (TVBN) dramatitically increased during storage periods (p<0.01). In the result of sensory evaluation, general acceptability points had been rated high in the first day of storage, and then, the points were decreased significantly on the third day (p<0.05). General acceptability points ranged from 8.86 to 10.68. Accordingly, Broiled Spanish Mackerel is highly recommendable cook/chill system. Considering the DHSS standards for storage, the ideal shelf-life recommended for Broiled Spanish Mackerel is within 4 days excluding cooking day. For Broiled Spanish Mackerel, critical control points were purchasing and receiving of frozen Spanish Mackerel, heating, chilling, chilled storage, reheating and distribution.
Time and temperature, microbiological quality of sauteed beef or pork were assessed in five general hospital foodservice operations. The microbiological quality of basic ingredients was poor and strict temperature control of refrigeration was required during delivery, and storage after receiving. In pre-preparation and cooking phases, improper handling practices of employees such as reusage of wiping cloth, indiscreet use of cutting board, and food handling with contaminated hands were noticed. During cooking phase, internal temperature of sauteed beef or pork reached a temperature of $74^{\circ}C$ or higher and the microbiological quality was good in general except hospital A. In all but hospital B, cooked foods were held at too high temperature in humid kitchen environment where could have permitted considerable bacterial multiplication. The sanitary conditions of container, equipments, and supplies were poor and should be improved promptly. The critical control points identified were: Hospital A: basic ingredients, pre-preparation, cooking, and preservice holding; Hospical B: bll8ic ingredients, and pre-preparation; Hospital C: basic ingredients, pre-preparation, pre service holding, and service; Hospital D: basic ingredients, pre-preparation, preservice holding, and service; and Hospital E: basic ingredients, pre-preparation, pre service holding, and service.
