A new report released by the Centers for Disease Control and Prevention (CDC) raises the question on how clean pool water actually is after revealing that more than half of the public pools in the United States are often contaminated by fecal matter.
The CDC report said that over 58 percent of public pools in the country which they tested were positive for the presence of E.coli.
The agency added that E.coli bacteria is usually found in human feces and their presence in the public pools was a marker that either some of the swimmers experienced a fecal incident in the pool or had not rinsed themselves properly before entering the pool.
"Swimming is an excellent way to get the physical activity needed to stay healthy. However, pool users should be aware of how to prevent infections while swimming. Remember, chlorine and other disinfectants don't kill germs instantly. That's why it's important for swimmers to protect themselves by not swallowing the water they swim in and to protect others by keeping feces and germs out of the pool by taking a pre-swim shower and not swimming when ill with diarrhea", chief of CDC's Healthy Swimming Program, Michele Hlavsa said.
