Louisiana reports rising flesh-eating bacteria infections in 2025

BATON ROUGE reports that 20 Louisiana residents have been infected with Vibrio vulnificus in 2025, with four deaths, according to the Louisiana Department of Health. The latest update shows three new cases since July 31, bringing the year total to 20. Infections this year exceed the decade average of seven per year, and the four deaths are higher than the long-term yearly average of one.

Health officials say Vibrio infections occur when an open wound contacts coastal waters or when people eat raw or undercooked seafood, especially oysters. Those at higher risk include people with liver disease, cancer, diabetes, HIV, or thalassemia, and anyone on immune-suppressing therapy, acid-reducing medicines, or after stomach surgery. Practical guidance includes avoiding brackish or salt water with a wound and washing exposed cuts with soap and water, and seeking medical care if symptoms develop.

Rising cases in a warm coastal season highlight climate and health system pressures. The numbers push public messaging to be more targeted, reaching coastal workers, seafood handlers, and residents with chronic illness.

Messaging matters. If warnings feel distant, people skip them. A clear local plan that covers testing, seafood safety, and wound care can reduce harm without stoking panic.
