Florida Seawater Bacteria: New Case in Sarasota County

SARASOTA COUNTY, FL — The number of people who have died in the state of Florida in 2016 due to Vibrio vulnificus bacteria remained at four as of Friday. The total number of people sickened statewide, however, climbed to 15.

The latest case originated in Sarasota County, according to the Florida Department of Health. The person sickened was exposed to the bacteria through exposure to seawater, said Mara Gambineri, spokeswoman for the department.

So far in 2016, Sarasota County has witnessed two cases and Manatee County one. Pasco, Pinellas and Hillsborough counties have yet to report any cases. Deaths so far this year from the bacteria have involved residents in Broward, Palm Beach, Citrus and Santa Rosa counties.

Vibrio vulnificus is a naturally occurring bacteria in raw shellfish and in warm, brackish/salty seawater,” Gambineri said. “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.

Vibrio vulnificus is often called the “flesh-eating” bacteria, but that’s not an entirely 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 2015, a total of 45 people across the state were sickened by Vibrio vulnificus. A total of 14 people died.
