Fourth Florida resident dies after contracting flesh-eating bacteria linked to oysters
Florida Reports Fourth Fatality from “Flesh‑Eating” Bacteria
A 75‑to‑79‑year‑old resident of Broward County has died after contracting Vibrio vulnificus, the bacterium that can cause a rare but deadly flesh‑eating infection. The death was added to Florida’s updated fatality list on Thursday, bringing the state’s 2026 toll to four people and 21 confirmed cases.
The Florida Department of Health did not disclose how the Broward victim became infected. Earlier this year the agency confirmed deaths in Bay, Palm Beach and Marion counties, with the most recent victim’s cause of death still under investigation. Health officials say the route of exposure could be ingestion of contaminated shellfish or contact with the bacteria in warm, brackish seawater through an open wound.
Why the Bacteria Are a Growing Concern
Vibrio vulnificus is naturally found in warm coastal waters. The Department of Health warned that the recent uptick in cases is linked to hurricanes Helene and Ian, which left standing or floodwater in several counties. “Severe weather events that cause standing or floodwaters pose a risk of exposure to the bacteria,” the agency said.
Florida’s 2026 case count of 21 follows a spike last year when the state logged 82 cases and 19 deaths. The 2024 outbreak was the most lethal in a decade, with 17 deaths and 74 cases. In 2022, Florida reported 74 cases and 17 deaths, making both years among the worst in recent memory.
How the Infection Spreads and Its Harsh Consequences
The Department of Health notes that most people contract vibriosis by eating raw or under‑cooked shellfish, particularly oysters. The bacterium can also be introduced through open cuts or wounds that come into contact with contaminated water. “Exposure can occur when a person eats oysters contaminated with the bacteria or enters contaminated water with an open wound,” the agency explained.
In healthy adults, Vibrio infection may cause a mild illness. However, the pathogen can lead to severe bloodstream infections, with a fatality rate of roughly 50 percent. Those with weakened immune systems or pre‑existing medical conditions are at especially high risk. “A recent study showed that people with these pre‑existing medical conditions were 80 times more likely to develop Vibrio vulnificus bloodstream infections than healthy people,” Florida officials added.
Symptoms of a serious infection include fever, chills, low blood pressure (septic shock), and blistering skin lesions. In some cases, severe wound infections can result in tissue damage that requires amputation.
Outbreaks Across the Gulf Coast
Florida is not the only Gulf‑Coast state grappling with Vibrio cases. Louisiana’s Department of Health reports 15 cases and six deaths as of September 9, with 14 attributed to wound or seawater exposure. Texas averages about 33 cases a year, while Mississippi has recorded three cases so far in 2026.
Public Health Advisory
Given the rise in cases, health officials urge residents to exercise caution when handling or eating raw shellfish and to keep open wounds covered while swimming or wading in coastal waters. “Most people get vibriosis by eating raw or undercooked shellfish, particularly oysters,” the Florida Department of Health reiterated.
While the outbreak remains concentrated in Florida, the pattern of increasing cases across the Gulf region highlights the broader public health implications of warmer coastal waters and extreme weather events. As the state continues to monitor the situation, officials remain on high alert for any further fatalities or spikes in infection rates.
