A spokesperson with Zoombezi Bay issued the following response:

It was brought to our attention that this news article from 2016 is being re-shared on social media. The article is out of date. Zoombezi Bay holds the highest standards for water testing. Zoombezi Bay installed UV sanitation equipment in 2017, which was a year before it was required to be installed in all Ohio pools by 2018. UV sanitation kills microorganisms faster than chlorine.

All pools are tested for proper chlorine levels every two hours, which is twice as frequent as state regulations require (every four hours). Additionally, there are signs throughout the park and at each water ride that state: “Anyone who has experienced a stomach and/or intestinal illness in the past two weeks may not participate in any water attraction” and “Diaper dependent persons must wear approved waterproof diapers in any water attraction.” To learn more about our water safety practices, please see these videos.

Original report:

The Delaware County Health District is currently investigating 19 cases of Cryptosporidiosis, a microscopic parasite that causes diarrhea, connected to Zoombezi Bay.

Health officials say the cases range from suspect, probable to confirmed, and includes those who already had diarrhea before swimming at the water park.

Dates of illness onset range from July 9 to July 26. Those who reported illnesses swam at Zoombezi Bay prior to July 20.

In response, the water park was super chlorinated on July 20 per the Ohio Department of Agriculture’s request.

Zoombezi Bay spokesman Patty Peters tells 10TV all pools are tested for proper chlorine levels every two hours, twice as frequent as state regulations require

According to the CDC, symptoms of cryptosporidiosis generally begin 2 to 10 days after becoming infected with the parasite. The most common symptom of cryptosporidiosis is watery diarrhea. Symptoms also include: stomach cramps or pain, dehydration, nausea, vomiting, fever, weight loss

Most people who have healthy immune systems will recover without treatment. Diarrhea can be managed by drinking plenty of fluids to prevent dehydration. People who are in poor health or who have weakened immune systems are at higher risk for more severe and prolonged illness.
