Abstract

The gado-gado food is the Javanese salad with peanut sauce consists of vegetable filling, lontong, potatoes, eggs, tofu and peanut sauce so has complete nutritional content, namely carbohydrates, fiber, protein and a little fat. This research aims to determine the biosafety of gado-gado food from street vendors around the Jember campus. 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). The amount of total bacterial in gado-gado from the street vendors around the Jember campus reached up to 105 CFU/g. The blue colony was identified as Raoutella planticola, which mostly comes from the soil and water. It is recommended that protect the street food from dust, air and need good handling of food service.
