The purpose of this study was to investigate the characteristics of the foodservice management practices, the equipment ratio of sanitary facility/equipment, and dietitians' perceptions of (i) the barriers to sanitary management and (ii) the sanitary management performance level in the welfare institutions for the disabled in Korea. The survey was conducted during the period from September 7 to October 15, 2006. A total of 91 institutions(response rate 74.6%) were analyzed by using SPSS(windows ver. 14.0). The average number of meals served per day per an institution was 379. The majority(93.4%) of dietitians made decisions in procurement. The major part of the purchase was made through private contract. The factors affecting menu planning were nutrition, food preference, and cost, in the order of importance. Among the food items, fruits were infrequently served, while protein source foods and green leaf vegetables were almost daily served. The equipment ratio of sanitary facilities/equipment was 45%, which was relatively low. Most dietitians perceived 'limited availability of facilities and equipment' and 'the lack of support from financing department' as the major barriers in implementing a desirable sanitary system. Sanitary management performance in 'the food ingredient' was perceived as the lowest, while that in 'the uniform' showed the highest. The results of this study suggest that a proper supporting program on securing the facility/equipment and adequately trained employees are needed for successful sanitary management. Also, a more frequent supply of fruits for the disabled is recommended.

This study was carried out to develop the computer-assisted Hazard Analysis and Critical Control Point (HACCP) program for a systematic approach to the identification, assessment and control of hazards for foodservice manager to assure the microbiological quality of food in hospital foodservice operations. Sanitation practices were surveyed and analyzed in the dietetic department of 4 hospitals. Among them, one 762-bed general hospital was selected as standard model to develop computer-assisted HACCP program. All data base files and processing programs were created by using Foxpro package for easy access of HACCP concept. HACCP program was developed based on the methods suggested by NACMCF, IAMFES and Bryan. This program consisted of two parts: the pre-stage for HACCP study and the implementation stage of the HACCP system. 1. Pre-stage for HACCP study includes the selection of menu item, the development of the HACCP recipe, the construction of a product flow diagram, and printing the HACCP recipe and a product flow diagram. A menu item for HACCP study can be selected from the menu item lists classified by cooking methods. HACCP recipe includes ingredients, their amount and cooking procedure. A flow diagram is constructed based on the HACCP recipe. The HACCP recipe and a product flow diagram are printed out. 2. Implementation of HACCP study includes the identification of microbiological hazards, the determination of critical control points, the establishment of control methods of each hazard, and the complementation of data base file. Potentially hazardous ingredients are determined and microbiological hazards are identified in each phase of the product flow. Critical control points (CCPs) are identified by applying CCP decision trees for ingredients and each process stage. After hazards and CCPs are identified, criteria, monitoring system, corrective action plan, record-keeping system and verification methods are established. When the HACCP study is complemented, HACCP study result forms are printed out. HACCP data base file can be either added, corrected or deleted.

This study was conducted to compare and evaluate the difference in washing and disinfection when the Hazard Analysis and Critical Control Point (HACCP) protocol was applied to foodservice operations. The results of the survey were as follows: Among the 116 foodservice operations surveyed, 67.2% were HACCP-compliant and 32.8% were not HACCP-compliant. Also, 62.9% served meals once daily, and 79.3% conducted food safety education once a month. Compared to HACCP non-compliant foodservice operations, the disinfection performance of HACCP-compliant operations was significantly better concerning worktables (p<0.001), food inspection tables (p<0.001), preparation tables for distribution (p<0.01), serving tables (p<0.01), overflow and trenches(p<0.05), sinks (p<0.05), and insect attracting lamps (p<0.01). Similarly, the disinfection performance of HACCP-compliant foodservice operations was significantly better for 18 cooking utensils and personal tools such as food slicers (p<0.001), multiple cooking machines (p<0.05), tray carts (p<0.001), stainless steel tools (p<0.001), rubber gloves (p<0.05). Worktables (45.1%), serving tables (29.6%), sinks (37.0%), and scales (21.6%) were most often disinfected 'at the end of each task', while food inspection tables (36.5%), food preparation tables for distribution (31.2%), dish machines (34.2%), overflow and trenches (25.7%), and floors (25.8%) were most often disinfected 'once a day'. All cooking utensils were most often disinfected 'at the end of each task'. 'Chemical disinfection' was most frequently used in all foodservice facilities. To improve the food safety management of foodservice operations, it is necessary to apply the HACCP protocol and comply with the washing and disinfection manual.

Intestinal parasitic infections are a public health burden and a major cause of illness in developing countries. The diseases lead to various health threats, including growth retardation and mental health-related disorders, especially in children. We assessed the risk factors for intestinal parasitic infections among children aged 12-59 months residing in Nyamasheke District, Rwanda. A cross-sectional descriptive study was conducted using secondary data from 1,048 children aged 12-59 months whose stool samples were examined for the presence of intestinal parasites and whose results were registered in the laboratory information system in 2020. The prevalence of intestinal parasites in children aged 12-59 months was 53.2%. The dominant parasites were Ascaris lumbricoides (13.1%), followed by Giardia lamblia (10.9%), Entamoeba histolytica (7.9%), Trichuris trichiura (6.5%), hookworms (1.7%), and Taenia species (1.4%). A significant association was observed between intestinal parasites and the literacy of mothers or children's caregivers (odds ratio (OR)=5.09, P<0.001). Children from farming households were 2.8-fold more likely to contract intestinal parasitic infections than those from nonfarming households (OR=2.8, P<0.001). A significant association was also observed between intestinal parasites and food safety (OR=4.9, P<0.001). Intestinal parasitic infections were significantly associated with hand hygiene practices after using the toilet and washing fresh fruits before eating (P<0.001). The information gathered will help public health providers and partners develop control plans in highly endemic areas in Rwanda.

For successful food safety education in kindergartens, enjoyable play is essential. However, Korea lacks food safety education materials that help teachers create play activity plans suited to specific situations. This study aimed to develop food safety education guideline based on the Ministry of Education's guidelines and the 2019 Revised Nuri Kindergarten Curriculum. We reviewed current guideline and conducted focus group interviews to create content aligned with these guidelines. In our research, we structured educational content on elements of 'food safety management practices', including 'hand washing habits', 'food poisoning management', and 'food labeling information'. Nutrition and early childhood education professionals designed objectives and activities suitable for 3-, 4-, and 5-year-old children. The resulting guidebook provides a comprehensive resource for planning annual, monthly, and weekly food safety education. Educational topics, content, examples of children's experiences, and related Nuri curriculum were summarized in the food safety education guidebook. Guidebooks were provided to kindergartens to facilitate the application of these activities. The guideline developed in our study will enable kindergartens to make structured plans for food safety education, ultimately contributing to children's health and the formation of safe eating habits.

We investigated the food service management practices in child care centers operated by various types of foundations in the Chonbuk area of Korea. Self-administered questionnaires were collected from 125 child care center directors. The statistical analysis was completed using an SPSS v11.5 program. Approximately 82.4% of the directors were women with an the average age of 45 years old. The average number of children in each public and private child care center was 84.7 and 88.8, respectively (P<.001), and the difference in time of operation was significant(P<.001). Only 20.8% of the centers employed a dietitian, whereas 92.0% of the centers employed a cook, thus, food service was not managed by professionals in most centers. In approximately 99.2% of the centers, meals were prepared in a conventional manner. The difference in daily meal frequency was significant(P<.05), with approximately 85.6% of the centers serving snacks twice a day primarily to supplement the intake of nutrients(4.44 point) and to add fun to the daily lives of the children(4.12 point). Approximately 40.7% of the directors of public centers and 57.6% of the directors of private centers responded that the most difficult aspect of food service management was financial management. Overall, 56.8% of the directors responded that the details of financial management had the greatest effect on their ability to improve the quality of food service. In most centers, the center director was also the purchasing manager and half of them purchased food every day. Approximately 97% of the directors responded that they do not include instant foods in their menu plans but they would use them if the children wanted to eat them. These results indicate that the food service management in child care centers in the Chonbuk area is relatively inadequate. We strongly recommend that they hire dietitians for food service administration and focus on strengthening sanitation management.

본 연구는 2007년 6윌부터 10월까지 제주도에서 양식장이 가장 많이 밀집되어 있는 제주도 동부 연안에 위치한 양식장 4개소를 대상으로 하여 사육 용수, 양어 사료, 양식 넙치의 미생물학적 오염도를 조사하였다. 식품병원성 미생물 중 일반세균과 총대장균군 그리고 Escherichia coli O157:H7, Salmonella spp., Vibrio parahaemolyticus, Staphylococcus aureus, Bacillus cereus를 조사 하였다. 이번 연구를 수행하는 동안 동부지역은 집중적인 호우로 인해 전년보다 400 mm 이상의 많은 강우량을 나타내었다. 사육 용수의 검사결과 V. parahaemolyticus, Salmonella spp., S. aureus, B. cereus가 빈번하게 검출되었고, 양어 사료의 경우 Salmonella spp, S. aureus, B. cereus는 각각 $0{\sim}4.3{\times}l0^3$ CFU/ml, $0{\sim}2.7{\times}l0^4$ CFU/ml, $0{\sim}7.6{\times}l0^3$ CFU/ml 검출 되었다. 또한 양식 넙치의 미생물 검사 결과 적은 양이지만 Salmonella spp., S. aureus, B. cereus가 검출되었고, 총대장균군과 E. coli Ol57:H7은 검출되지 않았다. 이번 조사 결과로 보아 미생물학적 위해요소는 양식장의 작업 환경이나 주변 환경 등의 환경적 요인이 크게 작용하는 것으로 사료되며, 양식장의 위생관리에 작업자들은 주의를 기울여야 할 것으로 생각된다. 앞으로 이와 관련하여 수산물 위생에 대한 좀 더 체계적인 시스템을 도입하여 적용한다면 수산물에서 야기되는 문제점들이 해결되어 제주도의 청정 브랜드의 이미지를 더욱 부각시킬 수 있으며, 안전하고 깨끗한 수산물의 생산이 가능할 것으로 생각된다.

Water has always played a significant role in the lives of people. In urbanised Rome, with its million people. sophisticated supply systems developed and then fled with the empire. only to be rediscovered later But it was the industrial Revolution commencing in the eighteenth century that ushered in major paradigm shifts In use and altitudes towards water. Rapid and concentrated urbanisation brought problems of expanded demands for drinking supplies, waste management and disease. The strategy of using water from local streams, springs and village wells collapsed under the onslaughts of rising urban demands and pollution due to poor waste disposal practices. Expanding travel (railways. and steamships) aided the spread of disease. In England. public health crises peaks, related to water-borne typhoid and the three major cholera outbreaks occurred in the late eighteenth and early nineteenth century respectively. Technological, engineering and institutional responses were successful in solving the public health problem. it is generally accepted that the putting of water into pipe networks both for a clean drinking supply, as well as using it as a transport medium for removal of human and other wastes, played a significant role in towering death rates due to waterborne diseases such as cholera and typhoid towards the end of the nineteenth century. Today, similar principles apply. A recent World Bank report Indicates that there can be upto 76％ reduction in illness when major water and sanitation improvements occur in developing countries. Water management, technology and thinking in Australia were relatively stable in the twentieth century up to the mid to late 1970s. Groundwater sources were investigated and developed for towns and agriculture. Dams were built, and pipe networks extended both for supply and waste water management. The management paradigms in Australia were essentially extensions of European strategies with the minor adaptions due to climate and hydrogeology. During the 1970s and 1980s in Australia, it was realised increasingly that a knowledge of groundwater and hydrogeological processes were critical to pollution prevention, the development of sound waste management and the problems of salinity. Many millions of dollars have been both saved and generated as a consequence. This is especially in relation to domestic waste management and the disposal of aluminium refinery waste in New South Wales. Major institutional changes in public sector water management are occurring in Australia. Upheveals and change have now reached ail states in Australia with various approaches being followed. Market thinking, corporatisation, privatisation, internationalisation, downsizing and environmental pressures are all playing their role in this paradigm shift. One casualty of this turmoil is the progressive erosion of the public sector skillbase and this may become a serious issue should a public health crisis occur such as a water borne disease. Such crises have arisen over recent times. A complete rethink of the urban water cycle is going on right now in Australia both at the State and Federal level. We are on the threshold of significant change in how we use and manage water, both as a supply and a waste transporter in Urban environments especially. Substantial replacement of the pipe system will be needed in 25 to 30 years time and this will cost billions of dollars. The competition for water between imgation needs and environmental requirements in Australia and overseas will continue to be an issue in rural areas. This will be especially heightened by the rising demand for irrigation produced food as the world's population grows. Rapid urbanisation and industrialisation in the emerging S.E Asian countries are currently producing considerable demands for water management skills and Infrastructure development. This trend e expected to grow. There are also severe water shortages in the Middle East to such an extent that wars may be fought over water issues. Environmental public health crises and shortages will help drive the trends.

대부분의 외식산업은 생산 품목, 생산 방법, 생산 기술, 대상자들이 제조가공업체와는 매우 다르고 생산량, 취급인원, 영업규모등도 학교나 병원급식과는 여러 요소의 차이점을 가지고 있다. 본 연구는 소규모 외식업체에서 HACCP 시스템 적용을 위하여 종사자 대상 위생교육과 도입 전후의 미생물 분석과 시스템 도입에 따른 유의성 평가와 평가항목별 상관관계를 분석하였다. 또한 USN를 구축하여 도입 전후의 시간-온도관리 분석을 시행하여 효율성을 평가하였다. 위생교육 전후 조리 종사자의 위생업무 지식에 관한 평가 결과 개인위생, 식품의 공급 및 저장, 식품의 취급 및 배식, 기구의 세척 및 소독에서 유의적인 차이가 있었다. 또한 위생교육 전후 조리 종사자의 수행도에 관한 평가결과 식품의 취급 및 배식, 기구의 세척 및 소독, 작업 환경관리 영역에서 유의적으로 상승한 결과를 보였다. 조리 종사자의 교육 전후의 위생지식 결과는 개인위생(p<0.05), 식품의 공급 및 저장(p<0.05), 식품의 취급 및 배식(p<0.05), 기구의 세척 및 소독 영역(p<0.05)에서 유의적인 차이를 보였다. 모든 항목에서 정답률이 상승하였고 전체 문항에 대한 정답률은 교육 전 75%에서 교육 후 90%로 향상되었다. 조리 종사자의 위생업무에 대한 수행도 결과는 식품의 취급 및 배식(p<0.05), 기구의 세척 및 소독(p<0.05), 작업 환경관리 영역(p<0.05)과 총 점수에서 유의적인 차이를 보였다. HACCP 도입 전후의 소독에 따른 양상추 샐러드 미생물 품질분석 결과는 소독전 일반세균이 양상추 원재료 4.80 logCFU/g에서 소독 후 2.41 logCFU/g으로, 라디치오는 원재료 4.15 logCFU/g에서 소독 후 2.48 logCFU/g으로, 토마토는 원재료 4.10 logCFU/g에서 소독 후 평균 1.68 logCFU/g으로 나타나 중요관리점인 세척 시 소독을 통해 미생물 수치가 감소되었다. 멸치와 꽈리고추의 미생물적 품질결과는 원재료의 일반세균수는 각각 4.52 logCFU/g, 5.72 logCFU/g으로 나타났고, 볶았을 때 멸치는 2.07 logCFU/g, 꽈리고추는 1.50 logCFU/g으로 낮아졌다. 가열 공정 후 대장균군과 장내세균은 검출되지 않았다. 하지만 멸치꽈리볶음의 생산 공정은 재료별로 따로 볶아 버무리는 공정이 있어 최종식품에는 일반세균 4.33 logCFU/g, 대장균군 0.71 logCFU/g, 장내세균 1.65 logCFU/g, 황색포도상구균이 1.27 logCFU/g으로 검출되었다. 숙주나물의 미생물 분석 결과는 조리단계 및 배식단계에서 각각 4.20 logCFU/g, 4.68 logCFU/g의 높은 수치를 나타냈으나, 적용 후의 조리단계 및 배식단계에서는 각각 3.26 logCFU/g, 3.34 logCFU/g으로 나타났다. 숙주나물 및 잡채의 후처리 작업시 HACCP 적용 전 종사자 손의 일반세균수는 평균 5.90~5.99 logCFU/hand에서 적용 후 평균 0~2.30 logCFU/hand로 나타났다. 가열조리 후처리 공정에서는 교차오염을 줄이기 위하여 종사원의 손의 위생적인 관리가 필수적인 것으로 사료된다. 도입 전과 도입 후 2개월 시점의 조리 종사자의 위생지식점수 차이, 위생수행도 차이, 양상추 샐러드와 조리 종사자 손의 미생물적 품질 개선효과 간의 상관관계를 구하였다. 위생수행도의 변화와 양상추 샐러드의 미생물적 품질 개선 효과는 유의한 양의 상관관계(p<0.01)를 보여 위생 수행도가 높아질수록 식품의 미생물적 품질이 개선될 수 있다는 것을 보여주었다. 위생지식의 변화와 조리 종사자 손의 미생물 변화가 유의한 양의 상관관계(p<0.05)가 있었다. u-HACCP 시스템 도입 전후 온도관리에서의 3가지(온도측정의 정확성, 온도관리 효율성, 온도범위의 안정성)를 평가하였는데, 도입 전에는 업무시간에 냉장고 $5^{\circ}C$ 이하, 냉동고 $-18^{\circ}C$ 이하, 온장고 $57^{\circ}C$ 이상의 기준이 지켜지지 않은 것을 발견할 수 있었다. 하지만 도입 후 냉장고, 온장고, 식기세척기마다 자동경보로 위생 사고를 예방하였고 실시간 상황모니터가 설치되어 있어 HACCP 업무가 대폭 간소화 되었으며, 무엇보다 지속적인 위생교육으로 인해 직원들의 위험온도($5^{\circ}C{\sim}57^{\circ}C$)에 대한 이해도가 높아져 냉장, 냉동, 온장고의 기준온도의 준수율이 상승되었다. 따라서 유비쿼터스 센서 온도계를 이용하여 검수, 가공, 보존, 조리, 유통 등 각 단계별로 자동 모니터링이 가능해 잠재적 위험요소를 사전에 관리자에게 통보해 줌으로써 식품의 위생안전성을 확보할 수 있고, 무선 센서 네트워크의 특징을 이용하여 식재료 안전 관리 시스템에 적용할 경우 24시간 모니터링이 가능하여 신속한 개선조치와 이력 관리 모니터링을 통한 신뢰성 있는 품질경영 시스템을 구축할 수 있을 것으로 사료된다.
