Description:
This study reports the microbial flora of differently processed tilapia fish obtained from Olomoore market, Abeokuta, Nigeria. Samples were purchased, differently processed (using smoking, salting, freezing) and analyzed for the presence of bacteria. Microbial loads and characterisation were examined on the gills and the skin using standard microbiological procedures. The progression of growth was also monitored within I0-day storage period for the differently processed fish. 〈i〉Proteus vulgaris, Leuconostoc meseritiroides, Klebsiella planticola〈/i〉, Pseudomonas spp, 〈i〉Staphylococcus aureus, Bacillus subtitles〈/i〉, Enterobacter spp, 〈i〉Proteus vulgaris〈/i〉, Lactobacillus spp. were the bacteria isolated from the differently processed fish. There was no significant difference (P~B 0. 05) in the bacteria load of the gill during the first day of processing. However, significant variation (P~B 0. 05) existed in the bacteria load of the skin of the fish during the first day of processing. Although no significant difference (P~B 0. 05) was recorded in the bacteria load of the gill and the skin of the fish during the first day of processing in nutrient agar medium. In the tenth day frozen fish gill had the highest bacteria load while smoked fish gill had the lowest bacteria load there was significant difference (P~B 0. 05) in the bacteria load on the gill of differently processed fish gill. Similarly, there was significant variation (P~0.05) in the bacteria load of the skin of the fish during the tenth day processing.
