Hurricane Milton's aftermath: Floridians battle foodborne bacteria

In the United States, a major cleanup is underway following Hurricane Milton. Although the winds have weakened, floodwaters now threaten Florida residents.

American meteorologists warned that Milton could be one of the most destructive hurricanes in history. It drew strength from the very warm waters of the Gulf of Mexico and, as confirmed, twice reached Category 5 hurricane status. The maximum sustained wind speed reached nearly 205 mph. Now, health experts warn of an invisible threat lurking in the floodwaters.

A bacterium called Vibrio vulnificus is causing concern, prompting the Florida Department of Health to issue a warning.

"Seek medical attention immediately if you experience symptoms associated with Vibrio vulnificus, especially after exposure to floodwaters," the statement reads.

Over ten species of this type of bacteria cause diseases in humans and animals. Vibrio vulnificus is one of the rarest, but its infections are among the most serious. These bacteria naturally occur in coastal waters of some regions of the United States, especially during warmer months (from May to October). The waters pushed inland by Milton are of particular concern. Additionally, factors like heavy rainfall and mixing salt and fresh waters increase the rate of Vibrio vulnificus multiplication.

Vibrio vulnificus poses a threat primarily when it comes into contact with a wound on the body or affects someone with a weakened immune system. This can lead to an infection called vibriosis.

The main symptoms include vomiting, diarrhea, stomach cramps, and fever. In some cases, an infection with Vibrio vulnificus can also lead to localized infections (e.g., around a pre-existing wound on the body), causing pain, swelling, and discoloration. These situations can be life-threatening, sometimes requiring surgery and even amputation.

Vibrio infections occur in the United States, particularly in areas around the Gulf of Mexico. As of October 4th, Florida's medical databases recorded 64 confirmed cases of Vibrio vulnificus infections.
