Employees of Ventura Manufacturing in Zeeland complained Monday of irritated eyes, sore throats and difficulty breathing.
Zeeland Fire Chief Bill Gruppen said a smell lingered near a truck dock. Investigators learned that a truck driver had swept out debris there from a trailer before loading up. Gruppen said the trailer recently had carried a load of chili powder.
Employees were evaluated at the scene. Gruppen said no one required hospitalization.
