Flesh-eating bacteria kill seven in Florida, Louisiana

Vibrio bacteria infections killed a total of seven people in two states earlier this year, according to data released last week by state agencies. In Louisiana, five people died amid at least nine cases of reported infection, higher than the average for the last ten years, according to an update last week from state officials. Meanwhile, in Florida, there have been 14 reported infections and two deaths so far in 2026, according to health officials in the Sunshine State.

The bacteria are common in warm saltwater and brackish water, and can be contracted through open wounds in seawater. The flesh-eating bacteria can also be ingested by eating raw seafood, especially oysters.

Florida health officials warned that the bacteria can invade the bloodstream, causing a severe and life-threatening illness. Symptoms include fever, chills, decreasing blood pressure, blistering skin lesions, nausea, and other physical discharges. Louisiana officials urged citizens with open wounds to stay out of saltwater and brackish waters, regardless of the size of their cuts. They also should cook seafood thoroughly. The U.S. Centers for Disease Control said that if anyone suspected an infection, he or she should begin treatment immediately, as the infection can be fatal.
