Florida has plenty of things that make visitors think twice before stepping into the water. Sharks get the headlines. Alligators have their own reputation. Then there is Vibrio vulnificus, a bacterium most people probably never think about until summer arrives and another frightening headline starts making the rounds.
Florida health officials have now recorded 14 cases and two deaths from Vibrio vulnificus in 2026. The latest state figures were updated on August 6, and naturally, the words “flesh-eating bacteria” did most of the work online.
That phrase can make the situation sound like anyone walking barefoot near the Gulf is suddenly in danger. That is not what Florida’s numbers show.
Here is what officials have actually confirmed, how people get infected in the first place, and who is genuinely at risk this season.
What Florida Has Actually Confirmed
Florida has recorded 14 Vibrio vulnificus infections and two deaths so far this year. According to the state’s data, the deaths occurred in Palm Beach and Marion counties.
There is an important piece of information missing, though. Officials have not publicly explained how either person became infected.
That means it would be a mistake to assume both deaths came from oysters, swimming, or any single common source. Vibrio vulnificus can reach people in more than one way, and Florida’s public dashboard is designed to count cases rather than tell the complete medical story behind each one.
Earlier reports described the person who died in Palm Beach County as being between 80 and 84 years old. At that point, Florida had reported 11 cases statewide.
The number has since climbed, but nothing released by the state suggests all 14 cases belong to one connected outbreak.
Oysters Aren’t The Only Way People Get Infected
Raw oysters usually get mentioned first whenever Vibrio shows up in the news, and there is a reason for that.
Oysters feed by filtering seawater. If Vibrio vulnificus is present in that water, the bacteria can become concentrated inside the shellfish. Eating oysters raw or undercooked can therefore create an exposure route that disappears when shellfish are cooked properly.
But somebody can avoid oysters completely and still face a risk.
Warm coastal water can expose an open wound to the bacterium. That wound does not have to be dramatic. A cut, scrape, fresh tattoo, piercing, or another break in the skin can give bacteria an opening.
In other words, the oyster warning and the beach warning are related to the same bacterium, but they are not the same situation.
Someone eating raw shellfish at a restaurant faces one type of exposure. Someone wading through brackish water with a cut on their ankle faces another.
About That “Flesh-Eating” Label
Vibrio vulnificus does not literally eat flesh. In severe infections, bacteria can cause rapidly progressing tissue damage, including necrotizing fasciitis. That is where the frightening description comes from.
But not every Vibrio infection develops that way.
The CDC has also pointed out that group A Streptococcus is the most common cause of necrotizing fasciitis in the United States. So hearing the words “flesh-eating bacteria” should not automatically be interpreted as meaning every person diagnosed with Vibrio vulnificus will experience catastrophic tissue damage.
What makes this bacterium concerning is how quickly a serious infection can deteriorate in someone vulnerable.
That distinction gets lost remarkably fast once the story moves from a health department notice to social media.
Florida Has Seen Much Worse Years
The two deaths are serious, but Florida’s 2026 numbers need some historical perspective.
In 2022, the state recorded 74 cases and 17 deaths, according to the Florida Department of Health. Hurricane Ian contributed to an unusual increase, particularly in Lee and Collier counties, after storm surge and flooding created conditions where contaminated coastal water came into contact with more people.
Then came another unusually difficult year.
Florida reported 82 cases and 19 deaths in 2024, with Hurricane Helene associated with increased cases in several Gulf Coast counties. The following year, the numbers fell sharply to 33 cases and five deaths.
So far, 2026 is nowhere near those recent totals.

That does not mean the final number will remain at 14. August is still firmly inside Florida’s warmer season, when Vibrio activity tends to be higher.
It does mean that describing the current situation as an unprecedented surge would go beyond what the numbers support.
Some People Face A Much Bigger Risk Than Others
Vibrio vulnificus can infect otherwise healthy people, but severe illness is much more likely in people with certain underlying medical conditions.
The CDC identifies liver disease as one of the major risk factors. Cancer, diabetes, HIV, thalassemia, immune-suppressing treatment, low stomach acid, and some recent stomach surgeries can also increase a person’s chances of becoming seriously ill.
That changes how different people should view the same beach trip or seafood dinner.
A healthy person with intact skin walking along the shoreline is not facing the same level of danger as someone with liver disease entering warm coastal water with an uncovered wound.
The organism may be the same. The individual risk is not.
That is one reason broad warnings such as “Florida beaches have flesh-eating bacteria” can create more fear than understanding. They remove the very information people need to decide whether a warning applies directly to them.
Warm Water Is Part Of The Story
Vibrio vulnificus did not suddenly arrive in Florida this summer. It naturally occurs in warm coastal and brackish water. Florida’s climate gives it conditions it likes, particularly during the hotter months.
Water temperature matters because Vibrio levels tend to increase as coastal waters warm. Florida generally sees greater concern from late spring through early fall, which also happens to be when enormous numbers of residents and tourists are swimming, boating, fishing, and spending time around the coast.
That overlap matters.
More active bacteria plus more people in the water means more opportunities for exposure.
Storms can complicate the picture even further. Floodwater and storm surge can push coastal water into places people would not normally encounter it, which helps explain why Florida has seen unusually high case numbers after major hurricanes.
The bacteria are not new. The conditions surrounding exposure are what change.
The Advice Is Surprisingly Simple
Despite the frightening nickname, health officials are not asking Floridians to abandon beaches or seafood.
They are asking people to use a few precautions.
Shellfish should be cooked thoroughly rather than eaten raw or undercooked, especially by anyone in a high-risk medical group. People with cuts, wounds, fresh tattoos, piercings, or other broken skin should avoid warm saltwater and brackish water or properly protect the area.
There is also one warning that should not be brushed aside.
A wound that becomes unusually painful, swollen, hot, discolored, or rapidly red after coastal-water exposure deserves medical attention. Fever and chills can also signal a serious infection.
This is not the sort of infection where someone at high risk should spend several days waiting to see whether it clears up on its own. Severe Vibrio vulnificus infections can progress quickly, which is exactly why public health agencies emphasize early treatment.
Florida will continue to have Vibrio vulnificus in its coastal waters. That part is unlikely to make a dramatic headline because it is not new.
The more useful question is what people do with that information.
For most beachgoers, enjoying the water does not suddenly become reckless because Florida reported another case. For someone with an open wound or a medical condition that makes severe infection more likely, however, a few small decisions can matter considerably.
After hearing about Florida’s latest cases, would you still order raw oysters, or would you play it safe and get them cooked instead?
