⚠️ Five Florida Cases of ‘Flesh-Eating Bacteria’ Reported as Summer Beach Season Begins

As Florida heads into another hot and humid summer, health officials are keeping a close watch on a potentially deadly bacteria that thrives in the state’s warm coastal waters.

The Florida Department of Health has confirmed five cases of Vibrio vulnificus so far in 2026, with infections reported across five counties since March. The bacteria, often referred to by the media as “flesh-eating bacteria,” naturally occur in warm, brackish water where freshwater and saltwater mix.

🌊 What Is Vibrio vulnificus?

Despite its frightening nickname, the bacteria do not actually “eat flesh.” However, they can cause severe infections that rapidly destroy skin and soft tissue once they enter the body through an open wound.

The bacteria can infect people through:

🦪 Eating raw or undercooked oysters and shellfish

🩹 Exposure of cuts, scrapes, or wounds to contaminated coastal water

🌧️ Contact with floodwaters mixed with seawater

Importantly, health officials note that the bacteria cannot penetrate healthy, unbroken skin.

🚨 Why It Matters

While infections remain rare, Vibrio vulnificus is one of the most dangerous naturally occurring marine bacteria in the United States.

People at highest risk include:

• Those with liver disease

• Individuals with weakened immune systems

• People with diabetes

• Older adults

• Anyone with open wounds or recent surgical incisions

Symptoms can develop quickly and may include:

🤒 Fever and chills

🤢 Nausea, vomiting, and diarrhea

🔴 Redness and swelling around a wound

🔥 Warmth and severe pain

💧 Fluid leakage from skin lesions

🫧 Blistering skin infections

In severe cases, hospitalization and emergency surgery may be required.

📊 Recent Florida Numbers

Florida experienced:

• 33 cases and 5 deaths in 2025

• 82 cases and 19 deaths in 2024

The sharp increase in 2024 followed major flooding associated with Hurricane Helene. Experts say hurricanes and tropical storms can create ideal conditions by mixing freshwater and seawater over large areas and exposing residents to contaminated floodwaters.

🏖️ What Beachgoers Should Know

For most healthy people, a day at the beach remains very safe.

Health officials recommend:

✅ Covering cuts and scrapes with waterproof bandages

✅ Staying out of coastal water if you have an open wound

✅ Washing wounds immediately if they come into contact with seawater

✅ Avoiding raw oysters and undercooked shellfish

✅ Seeking medical attention quickly if symptoms develop after swimming or eating raw seafood

🌴 Summer Outlook

With Gulf and Atlantic water temperatures rising through June, July, and August, experts expect conditions favorable for Vibrio bacteria to expand along Florida’s coastline. The risk remains low for the general public, but awareness becomes especially important during the peak beach, boating, and fishing season.

Health officials emphasize that early treatment is critical. Anyone who develops unusual swelling, redness, severe pain, or blistering after exposure to coastal waters should seek medical care immediately.
