In Louisiana, a dangerous bacteria called Vibrio vulnificus is causing serious trouble. This year alone, six people have died, and 34 others have gotten sick from it. The bacteria loves warm, brackish water and can make people very ill if they eat contaminated shellfish or swim with open wounds.
The latest victims were two people who ate oysters infected with the bacteria. These oysters were harvested in Louisiana and served in restaurants in both Louisiana and Florida. The scary part? You can't see the bacteria just by looking at the oysters.
Vibrio bacteria are naturally found in coastal waters. They can cause infections if someone swims with an open wound, a recent tattoo, or piercing. But most people get sick from eating raw or undercooked shellfish, especially oysters. That's because oysters filter water, and the bacteria can build up inside them.
The Louisiana Department of Health is urging people to be careful. They say the bacteria are very active right now. The Centers for Disease Control and Prevention (CDC) warns that some Vibrio infections can lead to necrotizing fasciitis, a severe condition where the flesh around a wound dies. While diarrhea and vomiting are common symptoms, some infections can be so severe that they result in amputation or even death.
It's important to note that this year's numbers are the highest in a decade. Health officials are advising everyone to take precautions to avoid getting sick from this dangerous bacteria.
