MCCLEAN, Ill. (AP) — Officials in southern Illinois say about 60 farm workers have been treated after being exposed to pesticides.

McLean County Sheriff’s Sgt. Dan Gamble tells the Pantagraph that the workers, including teenagers, started to notice the pesticide’s effects Tuesday after it was sprayed Monday.

Mount Hope-Funks Grove Fire Department Chief Eric Fulk says the workers largely suffered skin irritations because they entered the fields too soon after the chemical was sprayed.

The crews were then called in from the field and stayed on buses while officials were notified of the incident. The workers were decontaminated with water and soap at a tent set up on the lawn of a nearby farmhouse.

The workers were then transported to a local church and were permitted to go home around 3 p.m.
