Four people have died in Florida from Vibrio vulnificus, a deadly flesh-eating bacteria found in warm coastal waters, according to state health officials. The bacteria, linked to four deaths this year and 11 infections in 2025, can enter the body through open wounds or raw shellfish consumption, leading to severe illness and potentially fatal outcomes.
Vibrio vulnificus, a member of the Vibrio bacteria family, is commonly found in brackish seawater and is associated with infections ranging from mild symptoms like vomiting and diarrhea to life-threatening conditions such as necrotizing fasciitis, often referred to as ‘flesh-eating bacteria.’ Florida Health has confirmed these deaths, with officials emphasizing the importance of awareness and prevention measures for those at higher risk, including individuals with chronic liver disease, diabetes, or immunocompromised conditions.
Health officials are advising the public to avoid swimming in warm saltwater with open wounds and to refrain from consuming raw oysters and other raw shellfish to minimize the risk of infection. For those who have already been exposed, it is crucial to seek immediate medical attention, as prompt treatment with antibiotics can improve survival rates. In severe cases, surgical removal of dead tissue or even amputation may be necessary to prevent the spread of the infection. Florida Health has also highlighted the importance of proper hygiene and food safety practices, including the use of protective gloves when handling raw shellfish, to prevent cross-contamination.
The Centers for Disease Control and Prevention (CDC) notes that while infections from Vibrio vulnificus are rare, fatalities can occur quickly, often within days of the onset of symptoms. Health authorities have also reported a concerning trend in recent years, with a total of 82 cases and 19 deaths in 2024, compared to 46 cases and 11 deaths in 2023, indicating a growing public health concern. As part of their efforts to combat the spread of the bacteria, officials are urging individuals to stay informed and take preventive measures to protect themselves and their communities from this deadly pathogen.
