Fourth person dead from ‘flesh-eating’ bacteria linked to eating raw oysters

Key Points:

• A fourth person has died in Florida in 2026 from Vibrio vulnificus, a dangerous bacterium linked to raw or undercooked shellfish, particularly oysters, with 21 infections reported statewide this year.
• The latest fatality was a Broward County resident aged 75-79, though it is unclear how the infection was contracted; most cases result from eating contaminated shellfish or exposure of open wounds to contaminated water.
• Vibrio vulnificus naturally occurs in warm coastal waters, posing risks to swimmers, boaters, and those with open wounds or recent tattoos/piercings, especially during warmer months when the bacteria are more prevalent.
• Symptoms vary based on infection route, ranging from gastrointestinal issues after ingestion to severe wound infections that may require surgery or amputation, with rapid progression and potential fatality within days.
• Health officials advise thoroughly cooking shellfish to kill the bacteria and caution high-risk individuals to avoid raw or undercooked shellfish; infections can be treated with antibiotics but require prompt medical attention.
