초록
In the case of being contaminated with pathogenic Vibrio, shellfish pose a serious threat for public health. This study was conducted to investigate the presence of Vibrio parahaemolyticus and V. vulnificus in the seawater, bottom deposit and shellfish samples collected from the Gomso Bay, west coast of Korea. V. parahaemolyticus (30-80 CFU/g) was detected from seawater Jul. to Oct. and highest at Sep. V. parahaemolyticus was detected less than 10 CFU/g from seawater at Nov. with 14.6℃ of seawater temperature. V. parahaemolyticus (180-1,850 CFU/g) was detected more than 100 CFU/g from 3 kinds of shellfish, Short-necked clam Ruditapes philippinarum, Corb shell Cyclina sinensis, and Surf clam Mactra veneriformis, Jul. to Oct. and was highest in Surf clam at Oct. V. parahaemolyticus was detected less than 20 CFU/g from all tested shellfish at Nov. V. vulnificus (1.8-2.7 MPN/100 mL) was detected from seawater Jul. to Oct. and was not detected at Nov. V. vulnificus (18-236.7 MPN/100 g) was also detected from 3 kinds of shellfish Jul. to Oct. and was highest in Corb shell at Jul. V. vulnificus was not detected from all tested shellfish at Nov.
Abstract
In the case of being contaminated with pathogenic Vibrio, shellfish pose a serious threat for public health. This study was conducted to investigate the presence of Vibrio parahaemolyticus and V. vulnificus in the seawater, bottom deposit and shellfish samples collected from the Gomso Bay, west coast of Korea. V. parahaemolyticus (30-80 CFU/g) was detected from seawater Jul. to Oct. and highest at Sep. V. parahaemolyticus was detected less than 10 CFU/g from seawater at Nov. with 14.6℃ of seawater temperature. V. parahaemolyticus (180-1,850 CFU/g) was detected more than 100 CFU/g from 3 kinds of shellfish, Short-necked clam Ruditapes philippinarum, Corb shell Cyclina sinensis, and Surf clam Mactra veneriformis, Jul. to Oct. and was highest in Surf clam at Oct. V. parahaemolyticus was detected less than 20 CFU/g from all tested shellfish at Nov. V. vulnificus (1.8-2.7 MPN/100 mL) was detected from seawater Jul. to Oct. and was not detected at Nov. V. vulnificus (18-236.7 MPN/100 g) was also detected from 3 kinds of shellfish Jul. to Oct. and was highest in Corb shell at Jul. V. vulnificus was not detected from all tested shellfish at Nov.
