SISSETON, S.D. — The South Dakota Department of Health is investigating several reports of E.coli infections in Sisseton.

State Epidemiologist Dr. Josh Clayton said the Department of Health was first notified last week by a local physician or hospital after an E.coli infection was confirmed.

“We don’t have a single source that’s been identified at this point,” Clayton said.

While several people mentioned going to the Sisseton swimming pool, he said, there’s no confirmed link.

“We’ve been in contact with the local operator,” Clayton said. “Local samples have tested safe.”

According to Sisseton city offices, the pool is managed by a local nonprofit group. The president of that group is Dr. David Staub, a physician in Sisseton.

Staub said the pool has remained open since all water samples taken this summer have been normal.
