Abstract
This study was carried out to investigate the growth of pathogenic germ in fermented pork with Korean traditional seasonings. The samples, outside muscle of pork ham were cut by the shape of cube (7${\times}$12${\times}$2cm) and seasoned with five Korean traditional seasonings such as garlic paste (Tl), pickled Kimchi (T2), pickled Kimchi juice (T3), soybean paste (T4), red pepper paste (T5). The rate of meat to seasonings was same. The seasoned samples were fermented at -1${\pm}$1$^{\circ}C$ for 28 days. Microbial pathogens such as Escherichia coli O157, Listeria monocytogenes, Salmonella enteritidis were not detected in all paste and samples. When 1.5${\times}$l0$^3$ CFU/$\textrm{cm}^2$ of Escherichia coli O157 was inoculated, the numbers were slightly increased to 10$^3$-10$^4$ CFU/$\textrm{cm}^2$ at 3 days and gradually decreased to the level of inoculation at 18 days in all samples. In the inoculation with Listeria monocytogenes (8${\times}$l0$^4$ CFU/$\textrm{cm}^2$), the numbers were below 10$^3$ CFU/$\textrm{cm}^2$ during 28 days in T3 and T4, while they were increased to 10$\^$6/ CFU/$\textrm{cm}^2$ in Tl and T2 at 3 and 13 days respectively, and decreased to 10$^4$ CFU/$\textrm{cm}^2$. In the inoculation with Salmonella enteritidis (3${\times}$l0$^4$ CFU/$\textrm{cm}^2$), the numbers increased to 10$\^$5/ CFU/$\textrm{cm}^2$ at 18 days, but they were rapidly decreased to the level of initial inoculation at 23 days.
