Vibrio vulnificus Detected in May Seawater Samples... Caution Urged for Summer Seafood Consumption

The Gyeonggi-do Institute of Health and Environment has issued a warning after detecting Vibrio vulnificus bacteria in seawater samples collected on May 20. This year, the bacteria were detected about one month later than in 2023 and about one week later than in 2024.

Vibrio vulnificus infection typically occurs between May and June and is most prevalent from August to September. Infection can occur by consuming raw seafood or when contaminated seawater comes into contact with skin wounds.

Over the past three years, the number of reported cases in Gyeonggi-do was 13 in 2022, 9 in 2023, and 16 in 2024.

Symptoms of Vibrio vulnificus infection include acute fever, chills, abdominal pain, vomiting, and diarrhea. Swelling, rashes, and necrotic lesions can also develop on the skin. High-risk groups, such as people with chronic liver disease, diabetes patients, immunocompromised individuals, and those with alcohol addiction, are particularly vulnerable and face a higher fatality rate if infected, so extra caution is required.

Vibrio vulnificus is a halophilic bacterium that thrives in seawater with a salinity of 1-3%. Therefore, seafood should be thoroughly washed under running tap water and cooked at temperatures above 85°C. During marine activities, it is important to avoid skin injuries and to wash thoroughly with soap after swimming or water activities.

Jeon Jongseop, head of the Waterborne Disease Team at the Gyeonggi-do Institute of Health and Environment, emphasized, "Early prevention is crucial for Vibrio vulnificus infection," and urged the public to strictly follow preventive measures such as thoroughly cooking seafood, wearing gloves during food preparation, and avoiding contact with seawater if you have any wounds.
