Abstract : Jollof-rice sold in some restaurants in Bonny Island, Rivers State was examined for contamination by Salmonella typhii and Staphylococcus aureus. The microbial load (Total Heterotrophic Bacteria) in the rice was determined using the plate- count method. Salmonella typhii was isolated and characterized using Salmonella/Shigella Agar (SSA). Staphylococcus aureus was isolated and characterized using manitol salt agar. The microbial load of the Jollof- rice samples studied ranged from1.3 x 104 cfu/g to 1.0 x 103 cfu/g. Twenty-seven (27) isolates were recovered in the study, composed of 12 and 15 each of Salmonella typhii and Staphylococcus aureus. Due to the presence of these organisms in Jollof rice sold in restaurant in Bonny Island. The Jollof- rice is unsafe for consumption. Hence, for safety of consumers, a good hygienic condition should be maintained at the restaurants and food handlers who are carriers, should be trained in the area of good hygiene practices.
