Summer is almost here, and to escape from the Texas heat, many will flee to pools to cool off. But a new study has some questioning if they want to.

     According to a new study by the Center for Disease Control and Prevention (CDC) more than E.Coli is present in over half of all public swimming pools.

     A fecal indicator found was found in 58 percent of pool samples collected out of 161 pools from the metro-Atlanta area this month.

     Dr. Luis Ostrosky, with the UT Healthy Science Center in Houston, said this study is a good indicator to follow proper hygiene when swimming.

     “We need to remember that sick adults and sick children should not be going to pools,” he said. “They’ll contaminate the pools with their bad and harmful bacteria…. That will then affect the other swimmers.”

     The swimming pool is like a giant bathtub, when someone has a bowel movement in the pool it’s unsanitary but the main concern comes with diarrhea, Dr. Ostrosky said.

     “Fecal matter normally contains E.Coli … and 99.9 Percent of that will not be harmful to people,” Dr. Ostrosky said. “But there are some strands of it that can and will make you sick… severe diarrhea will contaminate the pool with bad bacteria that causes the fever, vomiting and other symptoms.”

    If you’re sick, stay away from pools.

     “If a child does see these symptoms days after swimming they could have an infection,” he said.  “A lot of the symptoms will show up days later, not right away.”
