How to protect yourself from Vibrio vulnificus, the bacteria found in some coastal waters
Vibrio vulnificus infections have doubled in Louisiana this season, causing multiple deaths and prompting health warnings to vulnerable individuals about exposure to coastal waters and raw seafood.
- Vibrio vulnificus infections have surged this year along the Gulf Coast, with Louisiana reporting 20 cases and four deaths so far in 2025.
- This increase follows a background of rising Vibrio infections linked to warmer Gulf waters and climate change, which help bacteria proliferate and spread northward.
- Health officials warn that the bacteria enter through small skin wounds or by eating raw or undercooked shellfish, especially oysters, and cause severe illness often requiring multiple surgeries or amputation.
- Florida has seen 17 Vibrio vulnificus infections and five fatalities so far this year, with the number of deaths being quadruple the usual seasonal count. Retired fisherman Bernie Stewart emphasized the seriousness of the situation, warning, "This ain’t nothing to play with."
- Officials urge people to avoid exposure when having open wounds, to wash cuts immediately, cook seafood thoroughly, and seek prompt medical care for symptoms to reduce risks from this highly lethal bacteria.
