Abstract
In Nigeria, people's general awareness of food safety has grown tremendously in recent years. In order to determine the safety of the fish for consumption, this study evaluated some microbiological quality of smoked marine fishes consumed around Nnewi City, Nnewi North Local Government Area of Anambra State, Nigeria. The research area's four markets provided samples of smoked fish, which were then analysed to find out how many bacteria were present. Herring (Clopea harengus, "Sawa"), Horse Mackerel (Trachurus trachurus, "Kote"), Great Barracuda (Sphyraena barracuda, "Panla"), and Atlantic Mackerel (Scomber scombrus, "Titus") were the chosen smoked fish samples that were tested. Fish samples were taken from open market places that were on display in different markets. The acquired results suggested that some types of bacteria were present in the fish samples under examination. Across all samples, the average total aerobic bacterial counts varied from 2.5 x 103 cfu/g to 7.3 x 103 cfu/g. The average coliform counts from the smoked fish were: 4.7 x 103 cfu/g for Clupea harengus; 5.1 x 103 cfu/g for Scomber scombrus; 3.7 x 103 cfu/g for Sphyraena barracuda. These values were obtained from the fish. However, the smoked fish samples that were chosen had an average Salmonella count (cfu/g) that varied from 1.3 x 103 cfu/g to 3.5 x 103 cfu/g. It is advised that users of smoked fish cook it to a suitable temperature in order to prevent food-borne illnesses in the study area, given the levels of microbial load found in the fish samples that were analysed.
