Microbiological characteristics of smoked and smoked–dried fish processed in Benin

Abstract This study aimed to assess the microbiological status of smoked fish (SF) and smoked–dried fish (SDF) processed in Benin, and to identify the contamination factors associated with these products. A total of 66 fish samples, including fresh fish and processed fish, were randomly collected from different processing sites and markets for microbial characterization using standard methods. The aerobic mesophilic bacteria (AMB) density varied from 2.9 to 9.5 Log10 CFU/g. Enterobacteriaceae, Escherichia coli, Bacillus cereus, Clostridium perfringens, yeasts, and molds were present in 63.9%, 27.8%, 55.6%, 58.3%, 61.1%, and 77.8% of samples, respectively, while no Salmonella spp., Listeria monocytogenes, and Staphylococcus aureus were found. The majority (66.7%) of SF samples and 22.2% of SDF samples were not compliant with the acceptable limit of
