Two More Deaths in Louisiana Linked to Flesh-Eating Bacteria in Oysters

Health officials in Louisiana have confirmed two additional deaths caused by Vibrio vulnificus, a rare but deadly “flesh-eating” bacteria often associated with contaminated seafood. Both victims reportedly consumed raw oysters harvested from Louisiana waters, raising new concerns about seafood safety as infections rise this summer.

A Growing Public Health Concern

So far this year, Louisiana has reported more than 30 infections linked to Vibrio vulnificus, with six resulting in fatalities. This marks one of the deadliest years on record for the state, where annual averages have historically been much lower. Experts warn that warmer coastal waters and changing environmental conditions are contributing to an uptick in bacterial growth.

How the Bacteria Spreads

Vibrio vulnificus thrives in warm, brackish waters along the Gulf Coast. People can become infected either by eating contaminated raw shellfish—particularly oysters—or by exposing open wounds to seawater where the bacteria live. Once inside the body, the infection can spread rapidly, sometimes leading to bloodstream infections, severe tissue damage, and even death.

Health officials emphasize that the bacteria poses the greatest risk to individuals with weakened immune systems, liver disease, or other underlying conditions. For those in high-risk groups, even a single raw oyster could be life-threatening.

Symptoms and Risks

Infections typically begin with stomach upset, fever, or chills but can escalate quickly. In severe cases, patients may develop blistering skin lesions or require surgery to remove infected tissue. The mortality rate is high, with approximately one in five infected individuals dying, sometimes within days of exposure.

Safety Measures for the Public

Authorities urge residents and visitors to take extra precautions during peak summer months:

Avoid eating raw or undercooked shellfish, especially oysters.
Cook seafood thoroughly to kill harmful bacteria.
Cover wounds and avoid swimming in warm coastal waters if cuts or scrapes are present.
Seek medical attention immediately if symptoms appear after consuming seafood or after seawater exposure.

Balancing Tradition with Safety

Oysters are a cultural staple in Louisiana’s cuisine, but health experts stress that safety must come first. While most oysters served in restaurants are safe, the surge in Vibrio cases serves as a reminder that raw seafood carries real risks.
