Flesh-Eating Bacteria From Contaminated Oysters Leaves Two Dead

Health officials have confirmed that contaminated oysters have led to two deaths and multiple infections due to the flesh-eating bacteria Vibrio vulnificus. The oysters, harvested in Louisiana, were served in restaurants in Louisiana and Florida. According to the states' health departments, Vibrio vulnificus has been linked to six deaths in Louisiana and five in Florida.

Vibrio vulnificus is part of a group of bacteria found in coastal waters, and most infections occur from consuming raw or undercooked shellfish, particularly oysters. In some cases, the bacteria can also enter the body through open wounds while swimming. The Centers for Disease Control and Prevention (CDC) states that the infection, known as vibriosis, can cause severe symptoms such as vomiting, diarrhea, and dehydration. In more severe cases, it can lead to necrotizing fasciitis, a condition where the flesh around an open wound dies.

Dr. Andrew Handel, a pediatric infectious diseases specialist, warned that the symptoms of skin infections from Vibrio vulnificus can progress quickly and become life-threatening. Jennifer Armentor from the Louisiana Department of Health described the current outbreak as "prolific."

The Louisiana Department of Health issued a statement on July 31 urging residents to take precautions against vibriosis. Prior to this outbreak, Louisiana reported 17 cases of Vibrio vulnificus in 2025, resulting in four deaths. Over the past decade, the state averaged seven cases and one death annually.

Health officials recommend ensuring shellfish is sourced hygienically and not left out for long periods. While healthy individuals typically experience mild symptoms, those who are immunocompromised or have chronic liver disease are at higher risk for severe health issues.
