WEST FARGO, N.D. (AP) – Two North Dakota parents are suing the City of Sisseton and others, claiming their young daughter got sick after swimming in the local pool and suffered permanent kidney damage. A federal lawsuit filed by Christopher and Katie Cameron of West Fargo says the 8-year-old girl was diagnosed with E.coli at the Sanford Fargo Medical Center a few days after swimming in the Sisseton pool last July.

KELO-TV reports the lawsuit claims at least four other children were sickened as well. The South Dakota Department of Health says a definitive source of the illness was not identified.
