The Florida Department of Health confirmed that a fourth person has died in the state after contracting Vibrio vulnificus, a bacterium often described as “flesh‑eating.” The latest fatality occurred in Broward County, though the department has not released further details about the individual.

Recent fatalities and case count

Earlier this year, three other deaths were reported in Palm Beach, Bay, and Marion counties. In total, 21 cases of Vibrio vulnificus infection have been confirmed across Florida, including two cases each in Broward and Miami‑Dade counties.

Historical context

Florida saw 33 confirmed cases and five deaths in 2025, while 2024 recorded 82 cases and 19 deaths. The health department noted that the spike in some counties during 2024 was linked to Hurricane Helene, which created conditions that favored bacterial growth.

How the bacteria spreads

Vibrio vulnificus thrives in warm, brackish seawater because it requires salt to survive. Infections are relatively rare, but when they occur they can be severe. Most people contract the bacterium by eating raw or undercooked seafood—especially oysters. Others become infected when an open wound is exposed to warm coastal water, according to the Centers for Disease Control and Prevention.

Symptoms and health guidance

The Florida Department of Health explains that ingestion of Vibrio vulnificus can cause vomiting, diarrhea, and abdominal pain. When the bacteria enter through a skin wound, they may cause severe skin infections that lead to tissue breakdown and ulcers. The department urges residents to avoid exposing open wounds to seawater and to ensure seafood is thoroughly cooked.

Precautions for residents and visitors

Health officials recommend the following steps to reduce risk:

• Cover any cuts or abrasions before swimming or wading in coastal waters.
• Cook shellfish, especially oysters, to an internal temperature of at least 145°F (63°C).
• Seek immediate medical attention if you experience sudden gastrointestinal symptoms after eating seafood or notice a rapidly worsening wound after water exposure.

By following these guidelines, Floridians can help protect themselves and their families from this potentially deadly infection.

Looking ahead

The department will continue to monitor case numbers and provide updates as new information becomes available. Residents are encouraged to stay informed through the Florida Department of Health website and local news outlets.
