“…Achinewhu and Amadi (1996) reported the involvement of Bacillus cereus in some street vended foods. Some strains of Bacillus (e.g., B. cereus) and Staphylococcus dureus are known enterotoxin producers (Jaweltz et al 1980;Bryant 1998). Staphylococcus aureus has also been isolated in moi-moi and akara (Sokari 1991) and in fish (Sokari and Anozie 1990).…”

The microbiological quality of selected ready‐to‐eat foods sold on the streets of Port Harcourt, Nigeria, was evaluated. Twenty to twenty‐eight samples each of 10 different types of foods were analyzed. About 50% of the foods were deep fat fried, 20% were baked, 10% each were either boiled, pasteurized and frozen, or fermented and chilled products. Methods of food preparation and handling practices influenced the shelf lives of the foods, and their implications on microbiological quality and safety are discussed. The heterotrophic counts were highest for yogurt and ice cream and lowest for chin‐chin and buns. Bacterial counts for pancake, moi moi, cake, meat pie and egg roll on McConkey agar gave comparable results with counts obtained on Deoxycholate agar. Eleven bacteria genera were isolated. Bacillus spp. and Klebsiella spp. occurred in most of the foods, followed by Staphylococcus spp. and Micrococcus spp., while other species exhibited a random distribution. Generally, the foods were microbiologically safe despite defective handling practices.

“…Some strains of Bacillus (e.g. B. cereus and Staphylococcus aureus are known enterotoxin producers (Bryant, 2007). The inherent danger in the association of B. cereus and S. aureus with or without their metabolic products in various foods, without further heat treatment is the possible outbreak of serious foodborne illness.…”

The microbiological quality of smoke-dried oysters (Crassostrea gasar) sold in Port Harcourt, Nigeria was investigated. The microbial load and pathogens in smoke-dried oysters from four major fishing ports: Kalabari (Ka), Bille (Bi), Okrika (Ok) and Nembe (NB) that supply the Port Harcourt market were evaluated and studied. Highest total viable counts were recorded in oysters from Bille and Nembe fishing ports and values ranged from 7.18-7.2log10 cfu/g and 6.7-6.9log10 cfu/g, respectively, while lowest counts were obtained in oysters from Okrika fishing port (5.75-5.9log10 cfu/g. The bacteria pathogens isolated were in the order of Staphylococcus aureus (45%), Bacillus cereus (25%), Micrococcus virans (15%), Klebsiella spp.(10%) and E.coli (5%). Among the predominant fungal isolates were Aspergillus niger, Aspergillus flavus, Penicillium spp, Neurospora spp. and Saccharomyces spp. Thus bacteria of aerial origin and storage fungi were isolated from smoke-dried oysters from the four major fishing ports that supply the fish market in Port Harcourt, Nigeria. The microbial load and pathogens in the smoke-dried oysters could be attributed to poor handling practices and faulty storage temperature by the fish vendors.

A total of 70 ear and nasal swab samples collected from 35 persons, 16-hospital population and 19 nonhospital population was examined for presence of Staphylococcus aureus. Eighty percent of the population studied were found to be carriers of S. aureus. Of the 28 positive cases, 35.7% were carriers of S. aureus in both the ear and nostrils, while 14.3% and 50.0% had it only in their ear and nostrils, respectively. The S. aureus isolates varied in their antibiotic susceptibility pattern when tested for their sensitivity to 16 antibiotics. Eighty percent of the isolates were resistant to more than one antimicrobial agent. All the isolates showed resistance to nalidixic acid and 100% sensitivity to rifampicin.
