Microbial contamination of smoked Anchovis

English

Smoked Anchovis spp. (Engraulis encrasicholus Linndeus) obtained from Senya Beraku (a major fishing centre), Kasoa (a marketing centre), and the Animal Research Institute Feedmill (feed-processing centre) was assessed for microbial contamination, using total viable count technique (pour plate method) and culture techniques, Sixty samples were aseptically and randomly selected into sterile universal bottles from the three study areas, with 20 samples from each study area. Total viable count ranged from I x 105 to 4.9 x 107 , 3.4 x 105 to 2.0 x IOS , and 6.5 x 105 to x 108 for Kasoa, Senya Beraku and Feedmill, respectively. A total of 139 isolates made up of 84 bacteria and 55 fungi were isolated. The 84 bacteria isolates belonged to I I genera: Streptococcus, Staphylococcus, Micrococcus, Salmonella, Enterobacter, Escherichia, Pasteurella, Pseudomonas, Bacillus, Listeria, and Aeromonas. The 55 fungi isolates belonged to five genera: Aspergillus, Trichoderma, Rhizopus, Penicillium, and Mucor. Since most of the organisms isolated may cause disease in man and animal, it is suggested that processing, handling, and storage of fish be improved to reduce contamination.
