ABSTRACT

Thirty (30) samples of chicken and beef suya varieties were aseptically collected from suya vendors at three different sale points in Umuahia Metroplis, Abia State. Studies on the microbiological quality of suya were carried out. The bacteria isolates included: Staphylococcus aureus, Escherichia coli, Bacillus cereus, Pseudomonas aeruginosa, Salmonella sp. Shigella sp. Streptococcus sp. and Klebsiella sp. while fungi isolates included: Aspergillus niger, Candida sp. and Penicillum. Samples (Bacteria load) from City Centre for all the chicken and beef suya produced 9.5 x 106cfu/g to 2.6 x 106cfu/g, those from Bank Road gave a range of 8.8 x 106cfu/g to 2.4 x 106cfu/g and those from World Bank gave a range of 8.5 x 106 to 2.8 x 106cfu/g. Samples (Fungi load) from City Centre for all the chicken and beef suya produced 4.6 x 102cfu/g to 2.3 x 102cfu/g, those from Bank Road gave a range of 4.0 x 102cfu/g to 2.3 x 102cfu/g and World Bank gave a range of 5.3 x 102cfu/g to 2.3 x 102cfu/g. These findings suggest that most of ready to eat foods sold by roadside vendors may constitute sources of microbial food poisoning, consequently, public health hazards. The need for improvement and maintenance of food hygienic practices by food handlers and vendors is emphasized
