Jul. 20, 2008 (McClatchy-Tribune Regional News delivered by Newstex) -- FORT WORTH -- Tests of water from Burger's Lake for the parasite cryptosporidium were not completed by Saturday as hoped, a Tarrant County Public Health spokeswoman said.

As of Friday, nine cases of cryptosporidiosis, the illness caused by the parasite, had been confirmed by the health agency. Officials have said they suspect that the people got the parasite while swimming in Burger's Lake, a popular summer spot in west Fort Worth.

Meanwhile, owners of public swimming pools are asked to "hyperchlorinate" their pools as a precaution, spokeswoman Vanassa Joseph said.

The U.S. Centers for Disease Control and Prevention are conducting the tests, she said.

"Cryptosporidium ( or crypto) is a chlorine resistant parasite, so even well-maintained pools, water parks, and interactive fountains can spread Crypto among swimmers," according to the CDC's Web site.

Crypto causes severe diarrhea, stomach cramps and nausea that can last two weeks. The parasite is found in human and animal fecal matter and thrives in water.

People who experience symptoms should report to county health officials at 817-321-4700.

Burger's Lake remains closed as recommended by health authorities.

What does "hyperchlorinate" mean?

For a short time, the amount of chlorine added to the water should be increased to about 20 or 30 parts per million. No swimmers should be in the pool.

Instructions are at www.cdc.gov/healthyswimming.

Water with such high levels of chlorine should not be discharged into gutters or storm drains, Joseph said.

Drinking water report

In its 2007 Drinking Water Quality Report, the city of Fort Worth noted the presence of crypto in our water.

Microscopic organisms such as crypto are common in surface water, according to the report. In 2007, tests of water from the lakes where Fort Worth gets its water detected low levels of the parasite. The report states that disinfection and filtration made the water safe to drink.

Who is most susceptible to crypto?

Infants.

Some elderly people or people with compromised immune systems, such as those undergoing chemotherapy for cancer or people who have received organ transplants.

How can I protect myself and my family when we are at a pool?

Don't swim if you have diarrhea or for two weeks after your diarrhea has stopped.

Don't swallow water while swimming or wading in pools, lakes or rivers. Avoid getting water in your mouth.

Shower before swimming; children, too.

Don't change a baby's diaper at poolside.

Take children on frequent bathroom breaks and check diapers often.
