BLOOMINGTON, Minn. - More than 300,000 people came to the Water Park of America at the Radisson Hotel Bloomington by Mall of America last year.

Water facilities can be entertainment but it can also become a breeding ground for waterborne diseases.

Jim Saccoman, general manger of the Radisson, said he worries everyday about it.

"Worrying is just part of the job," he said.

Saccoman became even more worried after hearing what happened in Duluth this week. The popular Edgewater Resort and Waterpark closed after an outbreak of cryptosporidium, crypto for short.

There are at least three confirmed cases and six suspected cases spanning from Minnesota to Wisconsin, according to Trisha Robinson, an epidemiologist with the Minnesota Department of Health (MDH).

The parasite is spread through feces. A person who has the disease often experiences diarrhea. The outbreak is still being investigated by the Department of Health but Edgewater was clear to re-open for business Tuesday.

Saccoman said his water park gets cleaned daily and inspected by the health department annually. On top of inspections they also have a unique UV system to help control bacteria as well as trained pool staff and engineering department.

Even with all the technology Robinson said people are the ones who can really prevent the parasite from spreading.

"Always take a shower before you get in the water. If you have children especially reminding them to take frequent bathroom breaks that's really important. Also, if you're changing diapers (make sure) you're changing those diapers at the designated diaper location.

Symptoms of crypto can take anywhere from two days to two weeks to appear.

Robinson said if you think you have symptoms of crypto contact your doctor and stay hydrated. Most healthy people can recover from Crypto but it can be fatal for those with weak immune systems.
