Recent headlines have warned about a rise in flesh-eating bacteria infections along the southeastern U.S. coast, including at least five deaths in Florida this year.
While Vibrio vulnificus (the bacteria at the center of the news) is most often linked to natural warm waters like beaches and estuaries, it’s part of a broader category of Recreational Water Illnesses (RWIs) that can also be a concern for pools and spas if proper maintenance isn’t done.
At M&M Pool & Spa Services, we believe it’s important for Florida pool owners to understand the risks, the differences between ocean-borne and pool-borne bacteria, and the steps you can take to keep your family and guests safe.
Vibrio vulnificus is a naturally occurring bacteria that thrives in warm, salty or brackish waters. It can cause severe wound infections, sometimes referred to as “flesh-eating disease”, and can be deadly if it spreads to the bloodstream.
While properly chlorinated swimming pools don’t harbor Vibrio vulnificus, the news serves as a reminder that any poorly maintained body of water can host dangerous bacteria.
According to the Dare County Department of Health, RWIs can be caused by germs or chemicals found in:
The most common RWIs in pools include:
These pathogens can cause skin infections, ear infections, respiratory issues, or gastrointestinal illness.
They often spread when chlorine levels drop or water circulation is inadequate, creating a breeding ground for harmful bacteria.
Florida’s heat and humidity speed up chlorine breakdown, especially during busy swim days or after heavy rain. If pool chemistry isn’t checked and balanced regularly:
1. Maintain Proper Chlorine Levels
The CDC recommends at least 1 ppm free chlorine for pools and 3 ppm for hot tubs.
2. Keep Filters and Pumps Running
Good circulation helps distribute sanitizer evenly and prevents stagnant water pockets.
3. Shower Before Swimming
This removes sweat, lotions, and bacteria that can consume chlorine.
4. Cover Cuts and Scrapes
Even in a backyard pool, waterproof bandages protect against infection.
5. Schedule Regular Professional Service
Weekly maintenance ensures that your water chemistry and equipment are always in safe ranges.
Our certified pool technicians provide:
By keeping your pool in Miami-Dade in optimal condition, we eliminate the conditions that allow dangerous bacteria (from Vibrio species to E. coli) to survive.
While the flesh-eating bacteria making headlines thrives mainly in natural warm waters, improper pool care can also expose swimmers to harmful RWIs.
A clean, balanced, and well-circulated pool is your best defense.
