What You Need to Know About Florida’s ‘Flesh-eating’ Bacteria

While Vibrio vulnificus infections are rare, they have become a focus of concern this summer after four fatalities in Florida — including one in St. Johns County — were linked to the bacteria. The infections have gained attention in the news, where the bacteria are often referred to as the “flesh-eating” bacteria due to their potential to cause severe tissue damage. Vibrio vulnificus can cause serious illness, especially in individuals with weakened immune systems, but UF Health experts say that this is not cause for panic or alarm for the general public.

Dr. Vivek Manikal, chief of infectious diseases at UF Health Flagler Hospital, offered reassurance. “There’s no reason to panic. We've seen a few cases, but infections are infrequent. While the bacteria are normally present in the water, severe outcomes like sepsis and death are quite uncommon. So, while there’s no great cause for concern, exercising caution is key when you’re out there,” he said.

“Brackish water might seem harmless, but for people with a weakened immune system, especially those undergoing chemotherapy, living with cancer or dealing with serious skin conditions, it carries serious risk so it is best to avoid, if possible,” says Dr. Manikal. “If you do find yourself in brackish water and notice redness, swelling, or pain around any nicks or cuts, get medical attention immediately."

According to the Centers for Disease Control and Prevention, around 80,000 Vibrio-related illnesses occur each year in the U.S., resulting in about 100 deaths, many of which could be avoided with timely medical attention.

How Vibrio Infections Occur

• Primarily from open wounds in contaminated water
• Can also result from eating raw or undercooked seafood, especially shellfish
• Higher risk for those with compromised immune systems or chronic illnesses

Community Safety Tips

• Follow health alerts and water advisories
• Cover open wounds near water
• Avoid swimming in discolored or foul-smelling water
• Cook seafood thoroughly
• Seek medical attention for symptoms such as fever, chills, skin infections or gastrointestinal issues after exposure
