Did you know that warm coastal waters can harbor more than just a pleasant swimming experience? As the summer heat continues, we’re hearing concerning reports about an increase in cases of Vibrio vulnificus, a bacterium that can cause severe illness. Doctors along the U.S. Gulf Coast have noted a rise in infections, with recent reports highlighting dozens of cases and several fatalities linked to this pathogen.

- Through open wounds: If you have a cut or sore, especially one that comes into contact with contaminated water, the bacteria can enter your bloodstream. This is particularly concerning for people with weakened immune systems or liver disease.
- By consuming contaminated seafood: Eating raw or undercooked shellfish, especially oysters harvested from contaminated waters, is another common way people get infected.
The ‘flesh-eating’ description
The term ‘flesh-eating’ bacteria might sound alarming, and it highlights the severe nature of some Vibrio vulnificus infections. When it enters the bloodstream, it can multiply rapidly, releasing toxins that cause a severe bloodstream infection (septicemia). This can lead to blistering skin lesions and rapid tissue death, which is why it’s sometimes called a
