The microbial load of ready-to-eat rice from both local fast food centers (local restaurants) and
Standard fast food centers (high class restaurants) within Benin City was investigated. The total colony
count ranged from 2.0 x 104 to 1.2 x 106 for bacteria and 8.0 x 104 to 2.0 x 105 for fungi. Four bacteria
were isolated: Bacillus cereus, Staphylococcus aureus, Escherichia coli and Klebsiella pneumonia. B.
cereus, which is mainly associated with food poisoning because of its ability to produce toxins, was
present in 37.5% of samples alongside E. coli. Two fungi were isolated: Saccharomyces cerevisae,
occurring in 50% of samples, and Aspergillus niger. Ready-to-eat rice from standard fast food centers
was found to have more microbial load and more microorganisms compared to ready-to-eat rice from
local fast food centers. The results of our study indicated that most of the ready-to-eat rice samples
examined did not meet bacteriological quality standards. Hence, it is recommended that a more close
supervision of ready-to-eat food should be carried out by relevant authorities.
