Florida health officials confirmed that a resident of Pinellas County has died after contracting Vibrio vulnificus, a bacterium that thrives in warm, brackish seawater. The death brings the statewide toll to five fatalities, matching the total reported for the previous year.
Statewide infection and fatality data
The Florida Department of Health reported a total of 23 infections across the state to date. The five deaths include the Pinellas County case and four additional fatalities confirmed in Bay, Broward, Marion and Palm Beach counties. While the number of deaths aligns with last year’s total, officials noted that 19 people died from the bacterial infection in 2024, according to the department’s latest release.
Details of the Pinellas County case
State officials have not disclosed the victim’s age, name or the precise location where exposure occurred. It remains unclear whether the infection resulted from consumption of raw seafood or from an open wound that came into contact with coastal waters.
Vibrio vulnificus is commonly associated with raw or undercooked shellfish, especially oysters. The bacterium can also enter the body through cuts or abrasions when individuals are exposed to warm saltwater or brackish environments. Healthy people typically experience mild gastrointestinal symptoms, but those with chronic liver disease, kidney disease or weakened immune systems face a markedly higher risk of severe illness.
Health risks, symptoms and prevention
Bloodstream infections caused by Vibrio vulnificus carry a fatality rate of approximately 50 percent. Research cited by health officials indicates that people with underlying health conditions are about 80 times more likely to develop bloodstream infections than otherwise healthy individuals. Overall, roughly one in five infected patients die, sometimes within 24 to 48 hours after symptoms appear. Survivors often require intensive care, and some may need limb amputation.
When the bacterium is ingested, victims may suffer vomiting, diarrhea and abdominal pain. Direct wound exposure can lead to severe skin infections, ulcerations and blistering lesions. If the organism reaches the bloodstream, patients can develop high fever, chills and septic shock, a life‑threatening condition that demands immediate medical intervention. Accurate diagnosis relies on specialized growth media applied to blood, stool or wound cultures.
Public health agencies advise the public to avoid raw oysters and other uncooked shellfish. Proper cooking methods include boiling or steaming shellfish in the shell until they open, then continuing to boil for an additional five minutes or steaming for nine minutes. Shucked oysters should be boiled for at least three minutes or fried at 375 °F for ten minutes.
Individuals with open wounds should keep them out of warm saltwater, brackish water and raw seafood juices. High‑risk persons are encouraged to wear protective footwear on beaches to prevent cuts from shells or rocks and to use gloves when handling raw seafood.
