“…Hall markets are not of good quality and are unsafe for consumption. The results correlates with earlier works [7,17]. The contamination of fishes may be due to environmental conditions during transportation to landing centers and whole sale markets through handling process that may be associated with infection [7,17,18].…”

Present case study was carried out during 2013, to assess the microbiological quality of three freshwater fishes (Hoplosternum littorale, Cichlasoma bimaculatum and Hoplias malabaricus) offered for sale at two local markets in region 6. Fishes were examined for microbial quality and compared to the recommended levels of U.S Food and Drug Association (FDA) and Environmental Protection Agency (EPA) for fish and fisheries product. The results revealed based on the statistical test CHI-SQAURE that the microbial levels for the three freshwater fishes deviated significantly from U.S FDA and EPA expected standard. ANOVA done on the results further showed that there was no significant difference in coliform level among fish species and markets and for E. coli level, there was also no significant difference except at p<0.01. In conclusion, the three freshwater fishes offered for sale at local markets were not of acceptable standard based on U.S FDA and EPA Acceptable level and thus implores risk to human health.

“…Fishes play an important role in human diets as good sources of animal protein that also provide other important elements necessary for the maintenance of healthy bodies (Dewi et al, 2011;Ravichandran et al, 2012). Because of its high nutritive value, sea fishes are a major vehicle for pathogenic microorganisms (Das et al, 2007;Geetha et al, 2014). Fishes begin hostile by both the aquatic environment and post-harvesting condition (Al-Sheraa et al, 2018).…”

Along with the raw fishes, dry fishes also have a huge contribution to meet up the demand of protein in our daily meal. The assay of microbiological quality is therefore needed to ensure the public health safety. The present study was emphasized on the existence of pathogenic bacteria in raw and dry fish. A total of 50 samples of raw fishes and sun-dried fishes was accumulated aseptically for microbiological quality analysis. Isolation of bacteria was done by spread plate method. All the samples including both (raw and dry) fishes harbored bacteria and fungi up to 106 CFU/g. E. coli was found in all samples as a specific pathogen. In case of raw fishes total viable count (TVC) and total coliform count (E. coli) were recorded up to 2.5x106 CFU/g and 5.2 x104 CFU/g respectively whereas a significant load of Salmonella spp. was observed in almost all samples. Staphylococcus spp. and Pseudomonas spp. were present up to 5 x102 CFU/g and 1.8 x 102 CFU/g respectively. Likewise, total viable count (TVC), total coliform count (E. coli) and fungal load were recorded in dry fish up 3.50 x 105 CFU/g, 1.2 x103 CFU/g respectively. Fungal growth was observed in all experimental raw and dried fishes. For most of the pathogenic isolates, higher rates of resistance were found against Ceftriaxone, Penicillin, Nalidixic acid, Neomycin. On the other hand, most of the isolates were found to retain higher sensitivity against Imipenem, Ciprofloxacin, Tetracyclin and Amoxicillin. This data suggested that the dry fish harbored fewer bacteria than raw fish and sun drying method is still a useful technique for the preservation of fish.

“…During transportation of these fish to land and wholesale market, the fish may also infect people associated in handling. When the consumers purchase these fish, they (fish with high bacterial load) are definitely transferred to the person who carries out them (Das et al 2007). Biological contaminants constitute the major cause of food borne diseases ranging from mild indisposition to chronic or life threatening illness (Phyllis 2007) and spoil food, including fish, meat, fresh fruits and vegetables (Pelczar et al 1986).…”

The bacteriological quality of mola fish (Amblypharyngodon mola) from three local fish markets as fresh and as frozen from three departmental chain shops of Dhaka metropolis were analyzed. The microbial quality parameters varied with different sources and the quality was found to be poor for local market fish samples. In total 24 samples were considered for bacteriological quality analysis and 10 pathogenic isolates for antibiotic sensitivity test to 12 antibiotics. The total bacterial count ranged from 1.8 ± 0.25×104 to 6.5 ± 0.75 × 106 cfu/g for fresh and 5.5 ± 0.55 × 103 to 7.0 ± 0.80 × 105 cfu/g for frozen mola. The highest total coliform count of mola was 8.0 ± 0.55 × 104 and 6.1 ± 0.40 × 103 cfu/g for local market and departmental chain shop, respectively. All fresh and frozen samples were observed having high quantity of E. coli above 102 cfu/g. Furthermore, Salmonella-Shigella was identified in 67% samples (75% of fresh and 58% of frozen samples) varied from 0.9 ± 0.00 ×102 to 5.3 ± 0.30 × 103 cfu/g whereas Vibrio spp.was confirmed in 79% samples (83% of fresh and 75% of frozen samples) of which 90% samples exceeded 102 cfu/g. Similar pattern was observed in Staphylococcus spp. with 83% of fresh and 58% of frozen samples (63% of total samples) beyond 103 cfu/g. In case of antibiotic sensitivity pattern of the indicator and pathogenic isolates, all of them were resistant to amoxicillin and penicillin. Most of the isolates were sensitive to bacitracin, ciprofloxacin, erythromycin and streptomycin. The findings proved that mola fish under this study was more or less contaminated and local fish market samples were highly privileged with food borne pathogens which confirmed the unhygienic condition of the market as well as the presence of antibiotic resistance bacteria in mola fish may threat to public health safety.
