ABSTRACT
The microbial quality of ugba a special oil bean seed recipe was investigated. A total of nine (9) samples were purchased from three markets (three from each market). The samples were cultured on Nutrient agar, Mannitol salt agar, MacConkey agar, Sabouraud agar aerobically.The total viable count ranged from 70.67 ± 4.16 in sample 3 from ndoru market to 134.00 ± 6.56 in sample 6 from ubani markets. For the fungal count, the highest count was recorded by sample 4 of ubani market (7.33 ± 1.53) while the lowest count was recorded by sample 8 from township market 3.67 ± 1.16. The bacterial isolates and their occurrence were Staphylococcus (100%), Escherichia coli (44%), Klebsiella species (56%), Salmonella species (22%), Pseudomonas (78%), Bacillus (100), Proteus species (67%). The fungal isolates and their occurrence were Fusarium species (11%), Saccharomyces (78%), Penicillium species (44%), Aspergillus species (100%). The result of this study showed high counts with diverse micro flora of public health importance. Hence, consumption of ugba samples is potentially hazardous to the public.
