The Centers for Disease Control and Prevention (CDC) recently found that 58 percent of public swimming pools in the Atlanta, Georgia area tested positive for traces of fecal matter.
According to CBS News, CDC researchers found the bacteria Escherichia coli (E. coli) in the pools.
E. coli is associated with contaminated food, but can enter a swimming pool via human feces, especially when people do not shower before entering a pool.
Pseudomonas aeruginosa, a bacteria that causes ear infections and “hot tub rash,” was found in 59 percent of the pools. The CDC said this result may be natural pool contamination.
However, the CDC also found two other bacteria, Cryptosporidium and Giardia, that are also spread via feces.
"Swimming is an excellent way to get the physical activity needed to stay healthy," said Michele Hlavsa, chief of the Healthy Swimming Program at the CDC. "However, pool users should be aware of how to prevent infections while swimming. Remember, chlorine and other disinfectants don't kill germs instantly."
