Vibrio vulnificus infections problematic as water warms on Gulf Coast

The Florida Department of Health said information it has provided recently on Vibrio vulnificus infections — including the launch of a new webpage — does not indicate a worsening problem.

“Several media outlets published stories that contained inaccuracies about the safety of Florida’s beach water related to cases of Vibrio vulnificus infections,” according to a press release. “Annually, the department issues a release to remind Floridians of ways to protect themselves and minimize exposure to [this] naturally occurring bacterium found in warm, brackish seawater.”

According to the Vibrio vulnificus webpage, those with fresh wounds are strongly encouraged to stay out of salty coastal waters. It also recommends that individuals who are immunocompromised (eg, those who have chronic liver disease, kidney disease or a weakened immune system) wear foot protection to avoid skin injuries while walking on the beach).

The infection can lead to skin breakdown and ulcers, and possible amputation. Eating raw shellfish harvested from such waters — especially oysters — also can lead to Vibrio vulnificus infection, and cause vomiting, diarrhea and abdominal pain. Those who suspect they may be infected should seek immediate medical attention, while physicians who note skin infection or gastrointestinal issues for those who have consumed raw shellfish should consider a diagnosis of Vibrio vulnificus, according to the webpage.

The Florida Department of Health has reported two deaths from eight incidents of Vibrio vulnificus infection this year. Mara Burger, press secretary for the Florida Department of Health, provided information to Infectious Disease News that showed that one of these deaths was caused by “multiple exposures,” while the other was a product of consumption of raw oysters.

The website indicates that the majority of cases of Vibrio vulnificus occur in the Gulf Coast states. The CDC received reports of more than 900 Vibrio vulnificus infections from those states alone, between 1988 and 2006 — before national surveillance was adopted.

Despite this threat, the department wants beachgoers to know that these infections are rare, especially for healthy people without open cuts or scrapes.

“Florida’s beaches and water are safe to enjoy responsibly — risk of infection is minimal if you take proper precautions,” according to the release. – by David Jwanier
