Abstract :

The bacteriological and mycological quality assessment of selected ready-to-eat foods sold in Kaduna State University (KASU) were investigated. A total of one hundred and sixty ready-to-eat food samples: including rice, beans, yam and waina (rice cake) were collected from twelve food vending sites which serves as the major ready-to-eat food vending centres to the student community. Pour plate methods were used for the isolation of bacteria on different media and the fungi on potato dextrose agar (PDA). The bacteria and fungi isolates were characterized and identified using standard techniques. A total of five species of bacteria and three species of fungi were isolated and identified. These bacteria species include; Escherichia coli, Staphylococcus sp, Salmonella sp, Pseudomonas sp, Shigella sp and the fungi species include; Aspergillus sp, Mucor sp and Rhizopus sp. The mean total aerobic bacteria plate count ranged from 2.3 x101 to 6.2x109 and fungal count ranged from 5.3×101 to 4.5x109. The level of some food contaminations were within acceptable microbiological limits in relation to the specifications by International Commission for Microbiological Specification for Foods (ICMSF), except for waina which constituted about 30% of the total microbial isolates having E.coli and Aspergillus sp as the most predominant and Shigella sp as the least predominant. This could be attributed to extensive handling, mixing and processing of the waina. The Hazard analysis critical control point (HACCP) systems should be enforced in foods sold on campus through stringent supervision of the ready-to-eat foods by relevant authorities to prevent possible outbreak of food borne illness.
