Pathogenic microorganisms, heavy metals, and antibiotic residues in seven Korean freshwater aquaculture species

Abstract

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.

Contaminations in Wild and Farmed Fish and Influence of Traditional Cooking Methods

“…Tetracycline residues were only found in flesh fish of F3 farm (Table 1). Choi J, et al [46] studied antibiotic residues in seven farmed fish species in Korea, and they detected only enrofloxacin (0.0305 mg/ kg) in Cyprinus carpio. Done HY, et al [47] investigated 47 types of antibiotics in diverse cultivated fish (rainbow trout, Atlantic salmon, tilapia, and catfish) and shrimp retailed in the US.…”
