Flesh-Eating Bacteria Causes Fifth Death in Louisiana Amid Rising Cases

Louisiana health authorities have announced the death of a fifth individual this year due to Vibrio vulnificus, a rare but deadly bacterium that thrives in warm coastal waters. The bacteria tend to be most active from May through October, and infection can result in severe health complications such as necrotizing fasciitis, a rapidly spreading tissue-destroying condition. Approximately 20% of individuals infected with Vibrio vulnificus succumb to the illness.

The specifics of how the recent victim contracted the bacteria remain unclear. Earlier cases in Louisiana have been linked to consuming raw oysters, a popular seafood delicacy, while others resulted from exposure to contaminated seawater through open wounds. Dr. Fred Lopez, an infectious disease expert at LSU Health, emphasizes that these infections are no longer confined to the Gulf Coast, citing the impact of global warming in expanding the bacteria's range along the East Coast.

Regionally, cases are on the rise, with Louisiana traditionally averaging around seven infections and one death annually. However, in 2025, the state has already reported 26 cases. Neighboring states such as Alabama, Mississippi, and Florida have also recorded infections, with Florida seeing eight fatalities. Cases have even been identified as far north as Massachusetts.

Health officials recommend precautions such as avoiding raw or undercooked seafood and preventing open wounds from contact with warm coastal waters to reduce infection risks. For more detailed information about Vibrio vulnificus, the Cleveland Clinic offers helpful resources.
