Deadly Florida Seawater Bacteria Claims 3rd Life

TALLAHASSEE, FL — The Florida Department of Health on Thursday confirmed the third Vibrio vulnificus bacteria-related death in 2017. Fifteen other people have been sickened by the seawater bacteria in counties across the state since the year began.

The latest bacteria-related death occurred in Santa Rosa County, according to state records. Details about the person who died following exposure are not being released, but the source of infection is known in this case. The person who died was exposed through an open wound that came in contact with bacteria-contaminated water, Mara Gambineri, FDOH’s spokeswoman, told Patch on Aug. 31.

The circumstances of exposure in the first two fatal cases are unknown. The other deaths reported in 2017 occurred in Brevard and Orange counties.

“Vibrio vulnificus is a naturally occurring bacteria in raw shellfish and in warm, brackish/salty seawater,” Gambineri explained in a previous interview. “Vibrio vulnificus exposures occur more commonly during the summer months when water temperatures rise – the majority of our cases occur between May and October. The bacterium does not pose a risk to a normally healthy person and Florida’s beaches and water are safe to enjoy responsibly.”

People can become infected with Vibrio vulnificus in one of two ways – by eating contaminated raw shellfish and through exposure to contaminated water by swimming with open wounds.

The 15 non-fatal cases confirmed across the state since the year began are as follows:

• Charlotte County – 1 case
• Citrus County – 1 case
• Collier County – 1 case
• Duval County – 1 case
• Escambia County – 2 cases
• Lee County – 2 cases
• Okaloosa County – 1 case
• Pasco County – 1 case
• Polk County – 1 case
• Santa Rosa County – 1 case (not including the fatality)
• Sumter County – 3 cases

Vibrio vulnificus is often called the “flesh-eating” bacteria, but that’s not an accurate label, the state has said. Most people who come into contact with the bacteria don’t show severe symptoms. Signs of exposure in normally healthy people include such symptoms as stomach cramps, diarrhea and vomiting.

“People with weakened immune systems, particularly those with chronic liver disease, have an increased risk of infection and should take precautions,” Gambineri said. “Additionally, people with any open cuts, scrapes or abrasions should avoid exposing the wound to seawater to prevent infection.”

When open wounds come in contact with Vibrio vulnificus, the CDC says infections that arise “may lead to skin breakdown and ulceration.” When that breakdown of skin tissue occurs, it’s caused by a serious complication, known as necrotizing fasciitis. It’s that complication that gives rise to the “flesh-eating” moniker.

“Necrotizing fasciitis is a rare disease that can be caused by more than one type of bacteria,” Gambineri said in a previous interview. “These include group A Streptococcus (group A strep), Klebsiella, Clostridium, Escherichia coli, Staphylococcus aureus and Aeromonas hydrophila, among others. Group A strep is considered the most common cause of necrotizing fasciitis. Vibrio vulnificus and necrotizing fasciitis are not one in the same.”

In 2016, there were 46 confirmed Vibrio vulnificus-related illnesses across Florida. Ten of those cases resulted in fatalities.
