Central Florida Man Dies From Vibrio Vulnificus Bacteria Infection

A 56-year-old resident of Winter Haven is the latest Floridian to die from the Vibrio vulnificus bacteria, according to local media reports, including TCPalm.

The victim contracted the disease after he want saltwater fishing. He was dead from the bacterial infection in three days.

As the Florida Department of Health  notes, Vibrio vulnificus is a bacterium that normally lives in warm seawater. It is part of a group of vibrios that are called "halophilic" because they require salt. Vibrio vulnificus is a naturally occurring bacteria in warm, brackish seawater.

While Vibrio vulnificus infections are rare, it has been responsible for at least a dozen deaths in 2015.

The Florida Department of Health  provides the following tips for preventing Vibrio vulnificus infections:

• Do not eat raw oysters or other raw shellfish.
• Cook shellfish (oysters, clams, mussels) thoroughly.
• For shellfish in the shell, either a) boil until the shells open and continue boiling for five more minutes, or b) steam until the shells open and then continue cooking for nine more minutes. Do not eat those shellfish that do not open during cooking. Boil shucked oysters at least three minutes, or fry them in oil at least 10 minutes at 375°F.
• Avoid cross-contamination of cooked seafood and other foods with raw seafood and juices from raw seafood.
• Eat shellfish promptly after cooking and refrigerate leftovers.
• Avoid exposure of open wounds or broken skin to warm salt or brackish water, or to raw shellfish harvested from such waters.
• Wear protective clothing (e.g., gloves) when handling raw shellfish.

Warning to Florida Beachgoers: Watch Out for Vibrio Vulnificus Infections

The Florida Department of Health (DOH) is reminding visitors to the state's beaches to take proper precautions to reduce the risk of contracting infections due to the Vibrio vulnificus bacterium.

The DOH stated that there have been eight reported cases of Vibrio vulnificus infections in 2015 through June 12, which include two deaths.

According to the DOH, Vibrio vulnificus is a bacterium that normally lives in warm seawater and is part of a group of vibrios that are called 'halophilic' because they require salt. It is a naturally occurring bacteria in warm, brackish seawater, and infections are rare.

According to an online resource about Vibrio vulnificus developed by the DOH, people can become infected with Vibrio vulnificus when they eat raw shellfish, particularly oysters. The bacterium is frequently isolated from oysters and other shellfish in warm coastal waters during the summer months. Since it is naturally found in warm marine waters, people with open wounds can be exposed to Vibrio vulnificus through direct contact with seawater. The infection is diagnosed by stool, wound, or blood cultures. There is no evidence of person-to-person transmission of Vibrio vulnificus.

According to the Centers for Disease Control and Prevention (CDC), among healthy people, ingestion of Vibrio vulnificus can cause vomiting, diarrhea and abdominal pain. In immunocompromised persons, particularly those with chronic liver disease, Vibrio vulnificus can infect the bloodstream, causing a severe and life-threatening illness characterized by fever and chills, decreased blood pressure (septic shock) and blistering skin lesions. Vibrio vulnificus bloodstream infections are fatal about 50% of the time.

There are a number of cooking-related tips for preventing Vibrio vulnificus infections, including not eating raw oysters or other raw shellfish, and wearing protective clothing (e.g., gloves) when handling raw shellfish. For beachgoers, the DOH recommends the following:

• Avoid exposure of open wounds or broken skin to warm salt or brackish water, or to raw shellfish harvested from such waters.
• Individuals who are immunocompromised (e.g., chronic liver disease, kidney disease, weakened immune system) should wear proper foot protection to prevent cuts and injury caused by rocks and shells on the beach.

Healthcare professionals are advised to have a high suspicion for this organism when patients present with stomach illness, fever or shock following the ingestion of raw seafood, especially oysters, or with a wound infection after exposure to seawater. If Vibrio vulnificus is suspected, treatment should be initiated immediately because antibiotics improve survival. Aggressive attention should be given to the wound site; for patients with wound infections, amputation of the infected limb is sometimes necessary.
