We evaluated the bacteriological content of seawater and shellfish in Gangjin Bay from January 2021–December 2023. We analyzed sanitary indicator microorganisms such as the coliform group, fecal coliforms, and Escherichia coli in the discharge water of major inland pollutants, seawater and shellfish. In 1,692 seawater samples from designated and non-designated areas, the fecal coliform counts ranged from <1.8 to 1,600 MPN/100 mL and <1.8 to 3,500 MPN/100 mL, respectively. The geometric mean (GM) and estimated 90th percentile of fecal coliforms in the designated and non-designated areas were 1.9–2.8 MPN/100 mL and 2.9–11.5 MPN/100 mL, and 1.9–2.8 MPN/100 mL and 3.9–17.4 MPN/100 mL, respectively. E. coli levels in 248 shellfish (oyster, shortenck clam, and ark shell clam) were <18 to 490 MPN/100 g, and their standard plate count ranged from <30 to 9,200 CFU/g. Fecal coliform levels and their radial spread in the impacted area of 10 contaminants were <1.8 to 790,000 MPN/100 mL and 5 to 5,153 m, respectively. Thus, the bacteriological levels of the in Gangjin Bay met the US water quality standards for designated oyster cultivation area and was classified as Class A under EU regulations.
Abstract
We evaluated the bacteriological content of seawater and shellfish in Gangjin Bay from January 2021–December 2023. We analyzed sanitary indicator microorganisms such as the coliform group, fecal coliforms, and Escherichia coli in the discharge water of major inland pollutants, seawater and shellfish. In 1,692 seawater samples from designated and non-designated areas, the fecal coliform counts ranged from <1.8 to 1,600 MPN/100 mL and <1.8 to 3,500 MPN/100 mL, respectively. The geometric mean (GM) and estimated 90th percentile of fecal coliforms in the designated and non-designated areas were 1.9–2.8 MPN/100 mL and 2.9–11.5 MPN/100 mL, and 1.9–2.8 MPN/100 mL and 3.9–17.4 MPN/100 mL, respectively. E. coli levels in 248 shellfish (oyster, shortenck clam, and ark shell clam) were <18 to 490 MPN/100 g, and their standard plate count ranged from <30 to 9,200 CFU/g.
