Health officials urge caution for Gulf Coast beachgoers amid surge of deadly bacterial infections

Health officials along the Gulf Coast are issuing urgent warnings to beachgoers due to a significant increase in severe, sometimes deadly, bacterial infections this summer. The primary concern is *Vibrio vulnificus*, a naturally occurring "flesh-eating" bacterium that thrives in warm coastal and brackish waters, with a notable surge reported in both Louisiana and Florida in 2026. Louisiana has seen at least 26 infections and five deaths, more than doubling last year's figures, while Florida has also reported a rise in cases and fatalities.

Infections typically occur when open wounds come into contact with contaminated seawater or through the consumption of raw or undercooked seafood, particularly oysters. Symptoms can range from mild gastrointestinal issues to severe bloodstream infections, necrotizing fasciitis, and in about 20% of cases, can be fatal. Those with weakened immune systems or chronic health conditions like liver disease are at higher risk for severe illness.

Officials are advising the public to exercise caution by avoiding coastal waters if they have open wounds, covering any cuts or scrapes with waterproof bandages, and thoroughly cooking all shellfish. Immediate medical attention is recommended for anyone who develops symptoms such as fever, chills, or rapidly worsening skin infections after exposure to coastal waters or raw seafood.
