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.

본 연구는 고사리와 도라지의 HACCP(Hazard Analysis Critical Control Point)시스템 적용에 필요한 미생물학적 위해 요소 분석을 위한 목적으로 수행되었다. 제조공정도는 일반적인 제조업체의 제조공정을 참고하여 작성하였다. 원료농산물의 미생물학적 위해요소 분석결과 일반세균수는 도라지에서 $6.2{\times}10^3CFU/g$ 로 가장 많이 검출되었다. 하지만, 소독공정 이후의 미생물검사 결과는 모든 균이 검출되지 않아 안전한 것으로 나타났다. 제조환경과 작업자의 미생물 검사 결과, 체계적인 세척 및 소독을 통하여 작업자 위생교육 등을 기반으로 개인위생과 함께 미생물학적 위해를 감소시켜야 할 것으로 사료된다.

Korea market of food service industry has been increased greatly since early 90's with the emergence of professional catering business and the expansion of school food service. Because of the characteristics of food service establishment, feeding many people at a time, there is always a high potential of foodborne outbreak which requires special sanitary management to prevent. Currently, many catering businesses are interested in HACCP(Hazard Analysis Critical Control Points), a new sanitary management system, and are trying to develop HACCP Plans for their food service establishment. Microbiological hazard analysis, a most important step for developing HACCP Plan, provides also basic information for evaluating sanitary aspect of prepared foods and their materials. There are not extensive data of microbiological hazard analysis for food service operations, especially for prepared foods and raw materials, which are helpful for developing a HACCP Plan. The extensive microbiological hazard analyses for 65 prepared foods and 51 raw materials selected from a couple of food service establishment were performed in this research. These results will provide useful information to determine hazards for developing a HACCP plan, and also to understand sanitary status for prepared foods and raw materials in food service establishment.

The purpose of this study was to evaluate the microbiological quality of non-heat-processed foods and the effects of HACCP implementation. Here, cabbage salad and cucumber&onion salad were selected and we investigated HA(Hazard Analysis) by checking microbiological quality, time and temperature, pH, and water activity at each processing stage. Thus, the receiving of spices and dressings, washing and sterilizing, cutting, cooking, and serving stages were all considered CCPs. Before implementing HACCP, microbial analysis showed that standard plate counts and coliform counts were higher than standard levels in most of the raw ingredients of each menu, as well as during the production process. The microbiological quality of the utensils and employee's hands used during cooking indicated levels requiring direct management. Evaluations of falling bacteria-in the foodservice establishment work areas ranged from $2{\sim}12CFU/plate$. However, after HACCP implementation, microbiological levels improved to standard levels fly sanitation education. Also, the number of falling bacteria were lower than before implementing HACCP. Therefore, it is essential the foodservice operations make efforts to implement HACCP, so that microbiological hazard levels are lowered and hygienic status improved.

This study evaluated the microbiological hazard of three Korean rice cake products (Gaepidduk, Injulmi, Julpyon). Microorganisms testing was conducted in various phases of the product flow of Korean rice cakes preparation, food equipment, environment work and cook employees at small scale. The results showed the presence of redbean paste, soybean powder and oil at levels as high as $10^5$ CFU/g on the hazard analysis of rice cakes ingredients. High levels of coliforms were detected in Julpyon products after 24 hr. and on the cooker's aprons. Clinical bacteria were not detected in any of the rice cakes. We concluded that there is a strong requirement for education related to personal hygiene for the production of hygienic rice cake products and for the publics health.

본 연구는 고춧가루의 HACCP(Hazard Analysis Critical Control Point) 시스템 적용에 필요한 미생물학적 위해 요소분석을 위한 목적으로 2014년 1월 10일~2014년 6월 13일까지 충주시 동량면 소재에 있는 용금농산에서 수행하였다. 고춧가루 제품의 모든 공정 단계들을 파악하여 공정흐름도를 작성하였고 미생물학적 위해를 제어할 수 있는 자외선살균공정에서 살균 시간을 변화시키면서 미생물의 변화를 시험한 결과 자외선 등 $20W{\times}12EA$, 살균 시간은 $63{\pm}3$초를 한계기준으로 결정하였다. 자외선살균 후에는 위해 미생물 검사 결과는 안전하나 제조환경과 작업자의 미생물 검사 결과 주기적인 세척 및 소독을 실시하여 미생물학적 위해를 감소시키고 작업자 위생교육 등을 통하여 개인위생을 준수해야 할 것으로 판단된다.

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.

This study was performed to analyze the microbiological hazards of ready-to eat sandwiches and to evaluate the effect of implementing a hazard analysis and critical control points (HACCP) for quality improvement of ready-to-eat sandwiches. In total, 174 samples were examined for the microbiological hazard analysis. About 37.4% of the samples had an aerobic plate count ${\geq}$6 log CFU/g, and the numbers of coliforms exceeded 3 log CFU/g in 82.2% of the samples. Additionally, Staphylococcus aureus, E. coli, and Salmonella spp. were detected in 10.3%, 4.6%, 1.1% of sandwiches, respectively. In contrast, E. coli O157:H7, and Listeria monocytogenes were not detected in any of the samples. The results of the microbiological verification after implementing a HACCP throughout the production process indicated that S. aureus, E. coli, Salmonella spp., E. coli O157:H7, and L. monocytogenes were not detected in any of the samples. Consequently, implementing a HACCP is effective for quality improvement of ready-to-eat sandwiches.
