ABSTRACT
This project work is aimed at examination of jollof rice served in hotels for pathogenic organisms and to find out possible pathogenic organisms in the food. Samples were collected from the hotels and were brought to the laboratory for analysis. The sample were homogenized and serial dilution of the sample was made out using 5ml sterile pipette and test tubes. The dilution were the cultured on different media, macconkey agar, and Nutrient agar, discrete bacteria colonies were observed and each colony was gram stained, the bacteria isolation were staphylococcus aureus, bacillus, Escherichia coli, these micro organism isolated are pathogenic and are toxin when ingested in contamination food.
