State environmental officials are warning people away from a tributary to Mill Creek in Johnson County because of a spill that occurred Friday.

People and pets should stay out of the tributary, which is in Lenexa east of Mill Creek, until further tests conclude it is safe to wade, Kansas health officials say.

The Kansas Department of Health and Environment issued the advisory on Friday and will issue another one once the tributary has been deemed safe.
