Deaths from Marine Bacteria on the Rise

Alert over Contaminated Seafood in the U.S.

Florida and Louisiana account for the most severe cases.

At least eight people have died so far in 2025 in the United States after contracting Vibrio vulnificus, a marine pathogen known for causing severe infections through open wounds or the consumption of raw seafood—especially oysters.

According to data from state health departments, Florida and Louisiana report the highest number of victims, with four deaths in each state. Additionally, Louisiana has confirmed 17 infections, while Florida has reported 13 cases to date.

Alabama and Mississippi have each reported one case as well.

Vibrio vulnificus lives in warm, brackish, or salty waters, particularly in coastal areas of the southeastern United States.

The bacteria can enter the human body through open wounds while swimming in the ocean or when handling infected shellfish. It can also cause serious infections if raw mollusks—particularly oysters—are consumed.

The Florida Department of Health issued an advisory recommending avoiding contact with seawater in the presence of cuts, scrapes, or recent scars. It also warned people who are immunocompromised or have liver or kidney disease to take extra precautions.

Louisiana reinforced the warning, noting that the fatality rate is high: one in five infected individuals dies, even with prompt medical care.

Hot Weather Season Worsens the Risk

The risk of contracting Vibrio vulnificus increases in the summer due to rising water temperatures, which favor the bacteria’s spread.

The combination of high temperatures and coastal tourism increases public exposure—especially among those unaware of the risks.

The Centers for Disease Control and Prevention (CDC) estimate that between 150 and 200 infections from this bacterium are reported annually in the U.S., with consequences ranging from amputations to death within days.

Health authorities emphasize the importance of not consuming raw shellfish, avoiding contact with the sea if you have any wounds, and seeking immediate medical attention if symptoms like fever, skin redness, or swelling occur after contact with saltwater.
