Predictive food microbiology(PFM) is an emerging area of food microbiology since the later 1980’s. It does apply mathematical models to predict the responses of microorganism to specified environmental variables. Although, at present, PFM models do not completely developed, models can provide very useful information for microbiological responses in HACCP(Hazard Analysis Critical Control Point) system and Risk Assessment. This study illustrates the possible use of PFM models(PMP: Pathogen Modeling Program win5.1) with milk in several elements in the HACCP system, such as conduction of hazard analysis and determination of CCP(Critical Control Points) and CL(Critical Limits). The factors likely to affect the growth of the pathogens in milk involved storage fixed factors were pH 6.7, Aw 0.993 and NaCl 1.3%. PMPwin5.1 calculated generation time, lag phase duration, time to level of infective dose for pathogens across a range of storage (Critical Control Points) and CL(Critical Limits). The factors likely to affect the growth of the pathogens in milk involved storage temperature, pH, Aw and NaCl content. The factors likely to affect the growth of the pathogens in milk involved storage temperature, pH, Aw and NaCl content. The variable factor was storage temperature at the range of 4~15$^{\circ}C$ and the fixed factors were pH 6.7, Aw 0.993 and NaC 1.3%. PMPwin5.1 calculated generation time, lag phase duration, time to level of infective dose for pathogens across a range of storage temperature.

Hazard Analysis Critical Control Point (HACCP) system application is expanded to food chain from farm to table to supply safe livestock products with consumers in Korea. The objectives of this study were to analyze the HACCP operating conditions in butcher shops and to suggest for better HACCP implementation. We analyzed the HACCP inspection reports for butcher shops implemented by the Korea Livestock Products HACCP Accreditation Service from 2007 to 2009 and from 2010 to 2012 to compare the rate of HACCP non-compliances. The overall rate of non-compliances was higher in 2010~2012 than 2007~2009. The current inadequate HACCP operating level was directly related with the business size. Ninety-nine percent of the butcher shops were very small business with under 10 employees in Korea, and these small-sized businesses usually had great difficulties in implementing HACCP due to lack of technical expertise and financial resources. To overcome the obstacles and to facilitate more effective HACCP application and operation in butcher shops, government should play a leading role in developing flexible and simplified HACCP-based system which merges both the pre-requisite and HACCP principles.

To guarantee the safety of rice cake production, the Hazard Analysis Critical Control Points system was applied to the production process. The purpose of this study was to analyze the microbiological hazards of the manufacture of rice cakes, and establish critical limits in the process of the manufacturing rice cakes. To control the microbiological hazards, the sterilization process was set to a critical limit. The process of manufacturing rice cakes can reduce these microbiological hazards during the steaming process. A microorganism test for each specimen was conducted three times and compared with before and after steaming processes. The finished product was conducted by microbiology experiment and the validity of the steaming process was verified. The results were determined to be capable of reducing the biological element of Critical Control Point via the steaming process. Microbiology such as aerobic plate count, coliform, Escherichia coli(E. coli), Listeria monocytogenes, Enterohemorrhagic E. coli, Salmonella spp., Bacillus cereus, Staphylococcus aureus and Clostridium perfringens was evaluated by the experimental method of Korean Food Standards Codex. Aerobic plate count was reduced by steaming process, and no microorganism were detected. All rice cakes in the finished product were judged to be safe for both the Escherichia coli and general bacteria. In conclusion, it suggested that a HACCP plan was necessary for management standard and systematic approach in the establishment of critical limit, problem resolution, verification method, education, and records management. Based on this study, it is intended to provide a baseline for improving quality control standards and improving hygiene levels for small manufacturers.

This research performed to evaluate a production processes reporting by the HACCP system of green vegetable juice products, containing lactic acid bacteria, stage of processing raw materials agricultural products and production facilities of general bacteria and pathogenic micro organism. General bacteria are found from four samples of storage of agricultural products at process stage and water was detected 8.67~14.67 CFU/ml. However, all samples were detected less than 105 CFU/ml as a legal standards after the process of UV sterilization. For the outcome of experiment of E.coli, E.coli O157:H7, B.cereus, L.moonocytogenes, Salmonella spp, Staph.aureus as the food poisoning bacterial, E.coli was detected until UV pre-step process in storage process and B.cereus was detected partly till 1st washing. Since all bacterial, Yeast and Mold are detected in main materials, pre-control method is a necessary to establish for decreasing with a number of initial bacteria of main materials and it is considered to establish the effective ways of washing and sterilization such as production facilities for cross contamination prevention of bacteria and Sthaphylococcus. Based on above results, the process of UV sterilization should be managed with CCP as an important process to reduce or eliminate the general and food poisoning bacterial of green vegetable juice products, including lactic acid bacteria. Therefore, it is considered to need an exhaustive HACCP plan such as control manual of UV sterilization, solution method, verification, education and training and record management.

신선 채소류 편의식품에 관련된 병원성 세균으로는 Listeria monocy togenes, Yersinia enterocolytica,A eromonas hydrophila 등이 포함된다. 이들 제품은 미생물(병원성 및 비병원성)을 감소시키거나 사멸시키기 위해 별도의 살균 또는 항균제재를 사용하지 않기 때문에 초기 원료에 존재하거나 혹은 가공 및 유통 과정에서 오염된 미생물이 제품에 그대로 존재할 수 있다. 따라서 이들 제품에서는 병원성 세균이 발견될 수도 있으며, 특히 냉장유통 중 온도조절이 불완전할 경우 그 가능성이 더욱 높아지므로 신선 편의식 채소류 제품에 대해서는 보다 철저한 위생관리가 필요하다. 이러한 측면에서 위해 요소 중점관리기법(Hazard Analysis Critical Control Point, HACCP)을 적용하면 미생물학적 안전성을 확보할수 있다. HACCP이란 특정 제품의 수확에서 소비까지 전 공정에 대해 위해 요소를 검토하고, 이를 조절하기 위한 특별한 수단을 규정하는 관리기법이다. 본 연구에서는 HACCP의 7가지 기본 원칙을 정리하여 실제 대파(green onion)의 최소가공 과정에 적용함으로서 미생물학적 안전성을 확보하고자 시도한 사례를 중심으로 검토하였다.

This study has been performed for 150 days from February 1 - June 31, 2012 aiming at analyzing biologically hazardous factors in order to develop HACCP system for the vinegared pickle radishes. A process chart was prepared as shown on Fig. 1 by referring to manufacturing process of manufacturer of general vinegared pickle radishes regarding process of raw agricultural products of vinegared pickle radishes, used water, warehousing of additives and packing material, storage, careful selection, washing, peeling off, cutting, sorting out, stuffing (filling), internal packing, metal detection, external packing, storage and consignment (delivery). As a result of measuring Coliform group, Staphylococcus aureus, Salmonella spp., Bacillus cereus, Listeria Monocytogenes, E. coli O157:H7, Clostridium perfringens, Yeast and Mold before and after washing raw radishes, Bacillus cereus was $5.00{\times}10$ CFU/g before washing but it was not detected after washing and Yeast and Mold was $3.80{\times}10^2$ CFU/g before washing but it was reduced to 10 CFU/g after washing and other pathogenic bacteria was not detected. As a result of testing microorganism variation depending on pH (2-5) of seasoning fluid (condiment), pH 3-4 was determined as pH of seasoning fluid as all the bacteria was not detected in pH3-4. As a result of testing air-borne bacteria (number of general bacteria, colon bacillus, fungus) depending on each workplace, number of microorganism of internal packing room, seasoning fluid processing room, washing room and storage room was detected to be 10 CFU/Plate, 2 CFU/Plate, 60 CFU/Plate and 20 CFU/Plate, respectively. As a result of testing palm condition of workers, as number of general bacteria and colon bacillus was represented to be high as 346 $CFU/Cm^2$ and 23 $CFU/Cm^2$, respectively, an education and training for individual sanitation control was considered to be required. As a result of inspecting surface pollution level of manufacturing facility and devices, colon bacillus was not detected in all the specimen but general bacteria was most dominantly detected in PP Packing machine and Siuping machine (PE Bulk) as $4.2{\times}10^3CFU/Cm^2$, $2.6{\times}10^3CFU/Cm^2$, respectively. As a result of analyzing above hazardous factors, processing process of seasoning fluid where pathogenic bacteria may be prevented, reduced or removed is required to be controlled by CCP-B (Biological) and threshold level (critical control point) was set at pH 3-4. Therefore, it is considered that thorough HACCP control plan including control criteria (point) of seasoning fluid processing process, countermeasures in case of its deviation, its verification method, education/training and record control would be required.

The aim of this study was to investigate the effect of hazard analysis and critical control point (HACCP) system application on microbial hazard management levels of pork and manufacturing environments. In this study, we compared and analyzed microbial levels in raw meat, finished products, and manufacturing environments (knifes, gloves, and cutting boards) of HACCP and non-HACCP meat markets. In addition, we surveyed the hygiene statuses of HACCP and non-HACCP meat markets. The general bacterial counts in raw meat, finished products, and manufacturing environments were lower in HACCP meat markets than in non-HACCP meat markets. Particularly, non-HACCP meat markets exceeded the Ministry of Food and Drug Safety microbiological recommendation criteria for raw meats (8.7%) and finished products (8.7%). Escherichia coli and coliform counts in raw meat, finished products, and manufacturing environments were also lower in HACCP meat markets than in non-HACCP meat markets. The biological hazard levels of finished products from non-HACCP meat markets were affected by raw meat and manufacturing environment. Moreover, according to questionnaire survey results, personal hygiene, manufacturing environment, and facility standards were lower in non-HACCP meat markets than in HACCP meat markets. Implementation of HACCP at meat markets is expected to minimize food poisoning by reducing the biological hazard levels to provide safe livestock products to consumers.

The purpose of this study was to evaluate hazard factors in the steps of production, holding and assembly and service of jabchae that were served by contracted management in school meal foodservice. And method of control with the Hazard Analysis Critical Control Point (HACCP)program was suggested. The hazard factors in jabchae product had come from the temperature, time, growth of microbiological equipment and utensils. Almost of raw materials, prepreparation and storage, cooking, holding, serving established the critical control point. It has shown that the microbiological quality of raw materials for jabchae was a little inferior at the time of receiving based on the total plate count(10$^3$∼10 $^{5}$ ), coliform(0∼10$^3$). However microbiological quality become acceptable level by washing and a few disinfection method. Microbiological growth has increased in 3hr at room temperature up to 5.1${\times}$10$^2$ after preparation of jobchae. In conclusion, it is extremly important to reduce hoiding and serving time and to avoid treating food within the danger zone for food safeness. In addition, the prevention of cross-contamination during mixing the ingredients with improper equipment and with insanitary treatments by workers was also important to keep the food safe in this foodservice facility.
