EAGLE GROVE, Iowa (AP) — Iowa authorities have punished a north-central Iowa egg facility for allowing wastewater to reach a creek. The Mason City Globe Gazette reports that the Department of Natural Resources said Daybreak Foods Inc. must pay an administrative penalty of $5,500.

The department says a heavy rain in August washed a recent field application of wastewater into the creek near the facility in rural Eagle Grove. The company has a permit to spread the wastewater but can’t let it run into surface waters.
