“…The densities of TCs and FCs in this study are in agreement with Donde et al (2014), who observed that the density of TCs in the skin and gills was higher that of than FCs in fish from Naivasha Lake, Kenya. The prevalence of coliform bacteria in fish could be linked to contamination from the surrounding water environment (Al‐Sheraa, 2018; Kluga, Kacaniová, Kantor, Kovalenko, & Terentjeva, 2017), and the presence in the gills could be attributed to the high specific surface area for bacterial attachment and high water flow passing through them, including organic substances (Kluga et al, 2017). In the present study, the highest TC and FC densities from the skin were recorded in the spring and winter, respectively, while the highest TC and FC densities for the gills were observed in the summer and winter, respectively (Figure 3).…”

Urbanization, livestock activities, and rainfall are factors that contribute to the contamination of inland water. This study aimed to determine the spatial and temporal variability of total coliforms (TCs) and fecal coliforms (FCs) in the surface water of San Pedro Lake as well as the gills and skin of Nile tilapia (Oreochromis niloticus) cultivated in the lake. The study consisted of seasonal sampling during an annual cycle. Using the multiple‐tube fermentation technique, we quantified the microbial load of TCs in the lake and fish. The median of the TC and FC groups in surface water showed differences during the seasonal cycle, in which a significant correlation was observed between rainfall and bacterial load in the lake surface water. There was a significant seasonal difference between FCs and TCs in the gills as well as in skin FCs. Anthropogenic activities in the watershed combined with rainfall influence the bacterial load of San Pedro Lake. However, the water quality is still classified as excellent and uncontaminated according to Mexican regulations with lower FC values acceptable for higher FC values. In addition, the bacterial load in tilapia from San Pedro Lake does not pose a risk to human health. Practitioner points Watershed livestock activities combined with rainfall increase fecal matter pollution in specific areas of the lake. San Pedro Lake displays satisfactory quality for aquatic life. The median fecal coliform population in lake fish (gills and skin) differs by season.

“…Quality and safety of the fish products and particularly frozen food is one of the main problems of food industry today. The presence or absence of food borne pathogens (particularly staphylococcus aureus and Escherichia coli) in a fish product is a function of harvest environment and sanitary conditions during capture, processing, distribution and/or storage (Hala et al, 2017;Al-Sheraa, 2018). This suggests that fishes can be contaminated by both aquatic environment and post-harvesting conditions.…”

This work assessed heavy metals [Copper (Cu), Iron (Fe), Cadmium (Cd), Zinc (Zn) and Lead (Pb)] concentrations and microbial load in the tissue (skin, fillet and gills) of some frozen fishes [Clupea harengus (herring), Scomber scombrus (Mackerel), Urophycis tenuis (White hake)] sold in Utako market using Flame Atomic Absorption Spectrophotometer (AAS) and standard microbiological procedures. The results obtained revealed that the concentrations of all the heavy metals determined except Zinc (Zn) were above the Food and Agriculture Organization (FAO) and World Health Organization (WHO) permissible limits in fresh water fish and fishery products. The total aerobic plate count (APC) was between 2.15×103 cfu/g and 47.6×103 cfu/g, total coliform count ranged from 1.85 × 103 cfu/g to 2.03 × 103 cfu/g and fungal counts ranged between 6.02x102 cfu/g and 18.3x102 cfu/g. The microbiological study showed that the skin had more load compared to other studied tissues and in all, the microbial load except APC also exceeded the FAO/WHO acceptable limits for frozen fish products. This study indicated that the products were not ideal for consumption due to bioaccumulation of these heavy metals and the issue of post-harvest contaminants that can multiply in case of defrosting which may impact negatively on the consumers. It is recommended that there should be proper handling and examination of frozen foods and they should be properly cooked before consumption.

“…Because of its high nutritive value, sea fishes are a major vehicle for pathogenic bacteria. Fishes can be contaminated by both aquatic environment and postharvesting condition (Al-Sheraa, 2018). Due to the attack of pathogenic bacteria and fungi a wide ranges of sea fishes spoilages occurs which adversely affect the economic condition in Bangladesh and as well as public health.…”

The present investigation attempted to evaluate the existence and survival of spoilage microorganisms in four common sea fishes (Poma, Rupchanda, Koral and Tuna) available in Bangladesh and to determine the effects of cooking temperature to optimize the growth of fish microflora. Moreover, the status of fish in frozen condition after cooking was also studied. A total 4 categories of sea fishes were collected from the local shops in Dhaka city. Raw, cooked and frozen fish samples were analyzed for the existence of pathogenic bacteria through the conventional cultural techniques and the confirmative biochemical identification procedures. Total viable bacteria were present in all four fish samples in raw, cooked and frozen condition up to 6 log CFU/mL. Most of the raw fish samples were found to harbor a huge population of microorganisms up to 5 log CFU/mL including the fecal coliforms. Several specific bacterial species like E. coli, Klebsiella spp., Salmonella spp., Shigella spp., Staphylococcus spp., Pseudomonas spp. and Vibrio spp. were present in raw samples. However, the microbial load reduced from the fish after cooking and the status was static in frozen condition. Thus, the incidence of fecal coliforms in raw fish may be considered as a serious threat to the public health upon consumption of such fishes.
