Florida reports first 2026 death from Vibrio vulnificus infection

Florida's Department of Health confirmed the state's first death in 2026 linked to Vibrio vulnificus, a bacterium that thrives in warm, salty coastal waters and is often called the “flesh‑eating” or “carnivorous” bacteria. The victim was an 80‑84‑year‑old resident of Palm Beach County.

Twelve infections have been recorded across the state this year, with cases identified in Palm Beach, Miami‑Dade, Lee, Bay, Hillsborough, Marion, Okaloosa, Polk and St. Johns counties. The infections are isolated; officials say there is no evidence of a common source or an active outbreak.

Vibrio vulnificus can enter the body through open wounds exposed to contaminated water or by consuming raw or undercooked shellfish, especially oysters. People at higher risk include older adults, those with liver disease, diabetes, kidney disease, weakened immune systems, or chronic wounds. Symptoms may progress rapidly to necrotizing fasciitis, sepsis, organ failure, or require amputation. The Centers for Disease Control and Prevention estimate a 20‑25% fatality rate for severe cases. Florida reported 33 cases and five deaths in 2025 and 82 cases with 19 deaths in 2024, the latter surge linked to Hurricane Helene’s impact on coastal waters.
