摘 要：The purpose of this study was to evaluate the storage conditions as a way to increase the safety of fermented sausage, with the specific objectives to investigate the effect of storage time, pH value, water activity and microbiological status （Lactobacillus spp and Enterobacteriaceae） on the levels of Yersinia enterocolitica in fermented sausages. For this experiment, meat was divided into four equal portions of 10 kg each. The first portion was control group （C1 group） without addition of Y. enterocolitica and starter culture. The second portion （CII group） was inoculated starter, the third portion （EI group） was inoculated with I1. enterocolitica and the fourth portion （Eli group） was inoculated Y.. enterocolitica and starter culture. Sampling was performed by randomly selecting two links of each sausage preparation at the 0, 3rd, 6th, 9th, 15th, 25th and 35th day of drying. Results show that Y. enterocolitica and Enterobacteriaceae were not detected after 25 d of storage. The results indicate that practice utilizing starter culture is satisfactory to reduction of pathogen if present. Thus, inclusion with starter cultures in a maturation period may increase the safety of fermented sausages.
