ABSTRACT

Safety of food is a basic requirement of food quality. A total of 10 samples of food (jollof rice) randomly purchased from ten different eateries in Michael Okpara University of Agriculture, Umudike Abia state, Nigeria, were brought into the laboratory for microbial analysis. Pour plate technique was used. Serial dilutions of the samples were used after one ml from each tube was pipetted into a nutrient agar plates and incubated for 24 hours at 37oC. The plates were examined for growth. Sub-culturing of colonies from the growth was done on bacteriological agar. All screened samples had levels of bacterial growth ranging from 1.0 X 104 to 9.0 X 106 cfu/ml. Staphylococcus aureus, Bacillus cereus, Salmonella spp, Escherichia coli and Shigella spp. were isolated and identified from the food sample. This study revealed that foods (jollof rice) are potential vehicles for transmitting food borne illnesses in Nigeria.
