  • The purpose of this study was to evaluate the microbiological quality of, and to assure the hygienic safety of, the kimbap production in the university foodservice facilities in accordance with the HACCP (Hazard Analysis Critical Control Point) Program. The time-temperature relationship and the microbiological quality (specifically, total plate count and coliform bacteria count) were assessed to find the critical control point (CCP) during each of the production phases. The average of the daily longest duration time of the kimbap at the facilities was 23.4 hours in summer, while 29.6 hours in winter. In the purchasing phase of the raw materials, the microbiological quality of laver, fish paste, carrot and cucumber in summer was not at an acceptable level according to the standard set by the Natick research center, especially the number of TPC and the coliform level of laver was higher than the threshold level. In the refrigerator storage phase, the temperature of the carrot was 7.4$^{\circ}C$. This temperature is far exceeding the standard so that the microbiological counts was increased by the 2 log cycle during the average storage time of 17 hours or more. In the preparation phase, the temperature of the blanching is too low compared to the standard. In the holding phase before serving, its time-temperature relationship was out of the FDA food code standard both in winter and summer. In the sewing phase, the number of microbiological count was higher than the threshold level in summer while that in winter was up to standard. According to the Harrigan and McCance standard, the number of microbiological count of the utensils was higher than the threshold level in summer while that in winter was up to standard.

Relationships between Actual Sanitary Management Practices during Production and Distribution, and Microbiological Quality of Dosirak Items Marketed in CVS (편의점 판매용 도시락 생산 및 유통과정시의 위생관리 실태와 시판제품에 대한 미생물적 품질간의 상관관계)

  • Sanitary management practices from 8 packaged meals (Dosirak) manufacturing establishments were surveyd during production and distribution and their microbiological quality of dosirak items marketed in CVS were analyzed. Correlation coefficients were calculated to deternine significant relationships between sanitary management practices and microbiological quality of packaged meals. The results of self evaluation on sanitary management practices indicated 'doing practice well' in personnel and equipment sanitation management but time-temperature control management were practiced satisfactorily only about 55% as compared with the managerial standard guidelines. Significant relationships between the status of actual sanitary management practices and microbiological quality of Dosirak items were not found, but general status of microbiological quality of Dosirak items revealed positive relationship with the size of operational structure and the status of time-temperature control management practices.

  • In this study, significant factors influencing on the quality and stability of fermented sausage, such as materials, processing conditions, and microbiological characteristics as well as topography during ripening, were documented. Since most fermented sausages are not heated during manufacture or before consumption, a strict control of the growth of pathogens and the selection of favourable conditions that encourage the specific growth and development of desirable microflora are particularly important. With respect to microbiological safety, hurdles, i.e., preservations(nitrite), redox potential, competitive flora, acidity(pH), and water activity($a_{w}$) are matters of importance to prevent proliferation of bacterial pathogens. Today, for ensuring the safety and quality of the final product, the application of starter cultures in combination with the proper processing is subsequently used in practice. For improving the efficiency of microbiological utility in the production of fermented sausages, the understanding of their topography is essential. The documented different points must be taken into account when HACCP systems set up for the manufacture of fermented sausages. There are continuous researches concerning desirable improvements to sausage fermentation with health enhancing properties.

  • It has been recognized that international food standards should be considered for a long time. The Codex Alimentarius programme initiated in the early 1960s has received valuable background documentation from the ICMSF (International Commission on Microbiological Specification for Foods) and also from ISO(the International Organization for Standardization). There has been a considerable move towards international harmonization of standards and methods of analysis. Many foreign countries recommend the guidelines for food microbiological standards quantitatively. To complement microbiological limits and tolerance levels for permissible number of defective samples, allowances should be made for sampling and other variations in laboratory methods. It may be necessary for guidelines of domestic food microbiological standards to be established so that the domestic food standards can be harmonized with foreign food standards. Food safety related microbiological guidelines of ICMSF, EU (European Union), UK (United Kingdom), China (Hong Kong) and Japan were reviewed and shown in examples.

  • The purpose of this study was to provide basic information about the usage frequency of foods and menu items that may have microbiological hazards in elementary school foodservice operations in order to prepare a sanitation management manual for the foodservice production process. Menus from 200 elementary school foodservice operations from June 2004 were analyzed. An analysis of the foodservice production process of the menu revealed that the following processes were used: heat process(63.9%), non-heating process(28.1%), and after-heating process(8.0%). The cooking methods used for side dishes were: Stir-frying(19.9%), Saenchae(15.6%), Jorim(15,1%), Sukchae(13.1%), Frying(11.3%) and so on. Overall, 85 menu items known to include microbiological hazards were offered a total of 3,537 times; they were Doegi-bulgogi(7.0%), Bibim-bap(5.2%), Oi-saengchae(4.6%), Kongnamul-muchim(4.2%), Ddeok-bokkeum(4.0%), Japchae(3.7%), and so on. To serve safe and hygienic foods, menus including microbiological hazards should be planned very carefully. Furthermore, if a menu is high in microbiological hazards and frequency, the manuals of sanitation management should be applied more thoroughly.
