The aim of this research is to determine the risk of Salmonella Sp and Staphylococcus Aureus bacteria resulting from consumption of snacks in the Cempae coastal platform area, Parepare City on public health problems. Type. This type of research is quantitative descriptive research with a Quantitative Microbial Risk Assessment (QMRA) approach. The results of calculating the annual Probability of infection (Pinf.annual) for Staphyloccus Aureus bacteria were obtained. For 7 snacks, the Pinf.annual value = 1, for Salmonella bacteria, the Pinf.annual value = 0 was not positively contaminated with Salmonella bacteria and in the calculation of the Probability of illness (Pill) for Staphyloccus Aureus bacteria, the Pill value was found for all snacks = 3.0 x 10-1, whereas for Salmonella bacteria it was not found in snacks. The conclusion is Characterizing the risk of disease for Staphyloccus Aureus bacteria, there are 7 snacks that have a high risk and Salmonella bacteria are not positively contaminated in snacks in the Anjungan Cempae area.
