Nine samples of freshly prepared kunu was taken from local vendors and hawkers at Tanke area, Ilorin, Kara State and analyzed for microbial quality. The pH of the samples ranged from 2.66 to 4.06. The total bacterial count ranged from 1.5×104 to 7.4×104 cfu/ml; the total coliform count ranged from 1.0x102 to 8.0x103cfu/ml; the faecal coliform count ranged from 0 to 3.0x103cfu/ml; the total fungi count ranged from 3.2x104 to 2.7x105cfu/ml. The presence of high microbial load was an indication of poor hygiene and/or poor quality cereals and water used in the preparation. The microorganisms isolated included bacteria: Listeria sp., Corynebacterium cystitidis, Aeromonas sp., Corynebacterium amycolatum, Corynebacterium sp., Corynebactarium pseudotuberculosis, Listeria innocua, Kurthia sp. and Corynebacterium ulcerans and fungi were: Mucor sp., Geotrichum candida, Saccharomyces cerevisiae, Saccharomyces sp., Debaryozoma hansenii, Aspergillus sp. The types and density of microorganisms recovered from the drink requires urgent measures to be taken by regulatory authorities in the processing and handling of the product before being sold to the unsuspecting general public and this could include disinfection of raw materials used, water treatment, sterile packaging, pasteurization of kunu and also adoption of aseptic techniques during production.TABLE OF CONTENT
