"Seafood Consumption and Water Play Caution"... Gangwon Provincial Institute of Health and Environment Strengthens Surveillance of 'Pathogenic Vibrio'

6 Ports in 6 East Coast Cities and Counties (Goseong, Sokcho, Yangyang, Gangneung, Donghae, Samcheok)

[Asia Economy Reporter Ra Young-cheol] The Gangwon-do Institute of Health and Environment Research will strengthen its year-round continuous monitoring system to reduce the risk of infectious disease outbreaks caused by pathogenic Vibrio contamination along the East Coast of Gangwon-do.

According to the institute on the 21st, the areas targeted for pathogenic Vibrio contamination investigation include 18 points across 6 ports in 6 cities/counties along the East Coast (Goseong, Sokcho, Yangyang, Gangneung, Donghae, Samcheok).

Sample collection is conducted at two seawater points per port (outer harbor, inner harbor) and one brackish water point (where seawater and freshwater meet). Monitoring is done once a month, and is intensified to twice a month from July to September when water temperature rises sharply and Vibrio outbreaks increase.

The term 'pathogenic Vibrio' refers to three species: Vibrio cholerae (cholera bacteria), Vibrio vulnificus (Vibrio septicemia bacteria), and Vibrio parahaemolyticus (gastroenteritis Vibrio).

Vibrio is a halophilic bacterium that requires salt in its growth environment. It begins to be detected in April to May and proliferates most during the summer months (July to September) when water temperatures rise.

Consumption of seafood contaminated with pathogenic Vibrio or contact with the marine environment can cause infectious diseases such as food poisoning or septicemia in humans.

Among pathogenic Vibrio, cholera infection cases have not been reported in South Korea since three cases were confirmed in 2016.

Infections caused by Vibrio vulnificus and Vibrio parahaemolyticus frequently occur every summer.

Vibrio septicemia (with a fatality rate over 50%) can develop not only from eating contaminated seafood raw but also from contact of wounded skin with contaminated seawater, so special caution is required.

To prevent infections caused by pathogenic Vibrio, it is advised to avoid eating raw fish and shellfish during the summer. Especially, individuals with underlying conditions such as chronic liver disease, alcoholism, diabetes, or immunosuppression should be cautious.

People with skin wounds should avoid skin contact with seawater (to prevent Vibrio septicemia), store seafood at temperatures below 5℃, and wash thoroughly with tap water and cook at temperatures above 85℃ before consumption.

Those with skin wounds should refrain from handling seafood, and cutting boards, knives, and other utensils used for seafood must be disinfected before reuse.

Kim Young-su, director of the Gangwon-do Institute of Health and Environment Research, stated, "We will strengthen continuous monitoring of pathogenic Vibrio contamination and share the investigation results with the infectious disease and hygiene management departments of the respective cities and counties to reduce the risk of infectious disease outbreaks caused by Vibrio."
