Vibrio vulnificus bacteria causes rising infections and deaths in U.S. and Europe

Health authorities in the United States and Europe are issuing warnings regarding Vibrio vulnificus, a bacterium known as the ‘flesh-eating’ bacteria that thrives in warm seawater and brackish water. In the U.S., the infection has caused seven deaths so far this year, including five in Louisiana and two in Florida. Louisiana officials reported nine confirmed cases, all of which required hospitalization, noting that all patients had underlying health conditions and were exposed to seawater through open wounds.

Florida has recorded 14 cases and two deaths. Experts note that the bacteria can enter the body through open wounds, abrasions, or the consumption of raw or undercooked shellfish, particularly oysters. The mortality rate is high, with approximately one in five infected individuals dying from the disease.

In Europe, the Robert Koch Institute has reported 17 cases and two deaths in Germany as of July 2026. Similar trends have been observed in the Mediterranean, where rising water temperatures are linked to the increased prevalence of the bacteria. Health officials advise beachgoers to cover wounds and avoid consuming raw seafood to mitigate the risk.
