“…Pathogenic microorganisms in freshwater aquaculture species Fish is a highly perishable product and spoils due to microbiological activity, chemical oxidation of lipids, and autolysis (23). Moreover, microbial spoilage is the main mechanism that affects fresh fish quality (24,25). In this study, the levels of pathogenic microorganism on seven kinds of Korean freshwater aquaculture species with relatively high commercial importance, including Japanese eel (Anguilla japonica), leather carp (Cyprinus carpio nudus), rainbow trout (Oncorhynchus mykiss), Korean bullhead (Pseudobagrus fulvidraco), freshwater snail (Semisulcospira coreana), far eastern catfish (Silurus asotus), and Chinese softshell turtle (Trionyxs sinensis) were measured.…”

“…The microbial spoilage of cultured freshwater fish is closely related to contamination of fish farms. Contaminated fish ponds (e.g., high bacterial load due to fertilization and human and animal wastewater) enable penetration of pathogens into fish tissue-including gills, the digestive tract, muscles, kidneys, and liver-and may be responsible for food-borne diseases (24,25). Several studies have shown that the concentration of bacteria such as Escherichia coli, Salmonella spp., and Staphylococcus aureus in water is proportional to the concentration recovered from fish organs and tissue (26,27).…”

This survey was performed to estimate the levels of pathogenic microorganisms, antibiotic residues, and heavy metals in seven Korean freshwater aquaculture species including ,, ,, ,, and . None of the ten foodborne pathogens tested in this study were found in any of the species collected from any of the aquaculture farms. Furthermore, no banned chemicals or antibiotic residues were found in any of the species collected from any of the aquaculture farms, except enrofloxacin, which was below guideline limits (0.1 mg/kg). Finally, no species had lead, cadmium, total arsenic, or total mercury concentrations above the Ministry of Food and Drug Safety (MSDF) guidelines (0.5, 0.5, 0.1, and 0.5 mg/kg, respectively). These results ensure the safety of freshwater aquaculture species and will be useful for developing consumption advisories of freshwater fishes.

efluente. O sistema de tratamento proposto foi eficiente na remoção de E. coli da água, sendo que, após estabilização do sistema, ocorreu remoção média de 95% da contaminação. A etapa contendo E. crassipes apresentou maior remoção média, porém mostrou diminuição da eficiência a partir de 60 dias após implementação do sistema. A remoção média das etapas contendo C. demersum e T. domingensis foi prejudicada devido à presença de E. coli no solo usado como substrato durante as primeiras semanas de experimento. Contudo Typha domingensis).The most probable number of E. coli in the water was quantified for supply site, effluent and at each stage of treatment (sedimentation and use of each type of aquatic macrophyte). We conclude that E. coli contamination in water supply and in fishpond can reach the environment through the effluent. The proposed treatment system was efficient in removing E. coli from the water, and when the system was stabilized the average removal efficiency of E. coli was 95%.The tank containing E. crassipes showed the highest removal average, even though it exhibited an efficiency reduction after 60 days of experiment.The average removal of the tanks containing C. demersum and T. domingensis was hampered due to the presence of E. coli in soil used as substrate. However, after the decrease of substrate contamination effect, these two plants were essential for the maintenance of water quality of the treated effluent, indicating the benefits of aquatic macrophytes diversity in treatment systems. The effluent quality was maintained even when some system steps presented a decrease of removal efficiency.

“…Wild birds have been known as a source of E. coli O157 and other pathogenic organisms (Wallace et al, 1997). Previous study indicated that E. coli O157:H7 E318 could attach to and penetrate through the mucus of channel catfish (Suhalim, Huang, & Chen, 2007). Fish from such contaminated culture system may be harvested for human food where it is sold live at farmers markets.…”
