초록

The purpose of this study was to determine the cleanliness of meat shops in Seoul
by assessing the extent of microbial contamination of beef and pork sold at these meat
shops. Samples were collected from January 2017 to March 2018. Experiments were
conducted to detect the presence of indicator bacteria associated with sanitation(aerobic
plate count, Escherichia coli count) and food poisoning, resulting in a total of 437
samples. As a result, 6(3.7%) domestic beef samples, 10(12.0%) imported beef samples,
6(3.6%) domestic pork samples, and 3(12.0%) imported pork samples were identified
which exceeded the acceptable aerobic plate count(5×106 CFU/g). Salmonella spp.,
enterohemorrhagic Escherichia coli, and Staphylococcus aureus were not detected in any
of the samples. However, Listeria monocytogenes was detected in 2 pork samples, and
Yersinia enterocolitica was detected in 2 beef samples and 5 pork samples. In order to
effectively manage contamination by Listeria, Yersinia, an
