This research is an exploratory study that investigates the biosafety of gado-gado street food around the Jember campus based on exposure to enteric microbes as an sanitation indicator using the chromogenic media. The isolated microbes were determined the fermentation profile using the BBL Crystal kit. Sampling was taken in three different places in zone 1 (A1), zone 2 (A2) and zone 3 (A3). The sampling time was carried out at 10am when the trader had just opened his stall (B1) and at 3pm before the trader closed his stall (B2).
