Florida reports fourth death from Vibrio vulnificus infection linked to oysters
A resident of Broward County, aged between 75 and 79, died after contracting Vibrio vulnificus, the fourth fatality in Florida this year, as health officials warn of risks from raw oysters and contaminated water.
Florida health officials confirmed a fourth death this year from Vibrio vulnificus, a bacterium often associated with raw or undercooked oysters. The deceased was a Broward County resident aged 75 to 79, though the exact source of infection has not been determined. The state has recorded 21 cases of the bacterium in 2026, adding to previous fatalities in Bay, Palm Beach and Marion counties.
The department noted that Vibrio vulnificus thrives in warm, brackish seawater and can enter the body through contaminated shellfish or open wounds exposed to polluted water. Bloodstream infections caused by the bacterium are fatal in roughly half of cases, and individuals with certain medical conditions are significantly more vulnerable.
Officials highlighted that severe weather events, such as hurricanes that create standing or flood waters, can increase exposure risk. Similar outbreaks have been reported along the Gulf Coast, with Louisiana documenting 15 cases and six deaths, Texas averaging 33 cases annually, and Mississippi reporting three cases as of August.
