Human and cattle, mostly swine are predominant reservoirs for E. coli O157. Swine butchering in Bali specifically in Denpasar is increasing each year.

Plate Count agar (PCA), Eosin Methylene Blue Agar (EMBA) and selective Sorbitol MacConkey Agar (SMAC) were applied in this study as well. Metallic green colonies were found and taken for Gram staining then were inoculated on the media of biochemical test (IMViC). Next, the colonies were inoculated on the media of SMAC and observed for existence of colorless colonies which was identified as E.coli O157. Singlepath E.coli O157 examination was applied to confirm the identification of E.coli O157. The results of IMViC and SMAC tests on 12 from

31 samples (38,71%) indicated positive of containing E.coli. Six from 31 samples (19,35%) positively contained E.coli O157. The conclution showed that 19,35% porks from pork traders in Denpasar City were contaminated by E.coli O157. (MEDICINA 2012;43:3-8).
