ABSTRACT
This study investigated the microbiological quality of hawked ready-to-eat African Salad (Abacha). Standard microbiological methods were employed. The media used for the culture and isolation of microorganisms included Nutrient agar, MacConkey agar and Sabouraud Dextrose Agar (SDA).The result shows that the predominant bacterial isolates from African salad belong to Escherichia coli, Streptococcus spp., Proteus spp., Staphylococcus spp. and Serratiamarcescen. The fungal spp. isolated includes Aspergillus spp., Mucor spp., Rhizopus spp. and Saccharomyces spp. The Total Aerobic Plate Counts (TAPC) ranged from 3.8 x 108 to 8.0 x 1010, Coliform Count ranged from 3.2 x 103 to 1.2 x 106, and fungal count ranged from 2.3 x 103 to 1.0 x 106. Based on the specifications by International Commission for Microbiological Specification for Foods (ICMSF), the level of contaminations was unacceptable and unsatisfactory and could be pose serious health challenge.
