For years after a cryptosporidium outbreak shut down public pools throughout Utah, managers were focused on teaching Utahns to keep poop out of the water. This year, they've moved on to everything else — pee, sweat and dirt.

At a kickoff event Tuesday at the Taylorsville Recreation Center, Salt Lake County Health Department leaders reminded swimmers it's not chlorine that makes their eyes red after diving in. The water purifier mixes with nitrogen in swimmers' sweat and urine and turns into chloramine, which is not as effective at fighting bacteria and irritates the eyes, spokeswoman Pam Davenport said.

"Preventing the irritation isn't rocket science," Rick Ledbetter, the health department's swimming pool supervisor, said in a statement. "It's common courtesy: Swimmers should use the pool to swim, the restroom to pee and the showers to wash up before getting in the pool. It's that simple."

The department offered a few key pointers: Take a bathroom break every hour. Shower with soap before swimming. And check diapers every half hour and wash your hands after changing a baby.
