Vibrio vulnificus infections reported along U.S. Gulf Coast

Health officials have reported approximately 23 to 30 cases of Vibrio vulnificus, a “flesh-eating” bacteria, along the U.S. Gulf Coast this year. The infections have resulted in at least eight deaths, with five fatalities reported in Louisiana and three in Florida.

The bacteria thrive in warm, brackish coastal waters and are typically contracted through the consumption of raw or undercooked shellfish, such as oysters, or through direct contact with seawater via open wounds. While many infections result in mild gastrointestinal distress, the bacteria can cause necrotizing fasciitis—a rapid destruction of soft tissue—and septic shock, particularly in immunocompromised individuals.

Louisiana has reported nine cases, exceeding its annual average. Health experts note that the prevalence of the bacteria typically increases between May and October as ocean temperatures rise. Risk can be mitigated by practicing proper wound care and ensuring seafood is thoroughly cooked.
