Abstract

On the purpose of epidemiological survey relate to food poisoning, a total of 114 samples of different salads collected from fast food Restaurants in Gyeonggi-do were for the presence of pathogenic microorganisms. Microbial assessment of salads revealed that TPC($1.1\times10\;\~\;8.4\times10^{5}\;CFU/g$) and coliforms($0\~5.4\times10^{4}\;CFU/g$) exceeded the standards by Solberg et al. ($TPC:10^{5}\;CFU/g,\;coliforms:10^{2}\;CFU/g$). Two pathogenic bacteria were isolated from salad samples, and identified by biochemical methods, including API identification systems. Isolates from PALCAM agar and MYP agar media were in 98.6, $99.8\%$ agreements with Listeria monocytogenes, Bacillus cereus at the species level, respectively. All 7 strains of Bacillus cereus isolates produced enterotoxin as revealed with CRET-RPLA.
