Organizers of the Illinois State Fair say they're not changing security procedures after vandals threw paint on a butter cow at the state fair in Iowa. 
Jeff Squibb is a spokesman for the Illinois Department of Agriculture. 
He tells The Pantagraph ( ) that a refrigerated case holding the butter bovine is locked all the time in the fair's Dairy Building, while a webcam streams live images of the sculpture.
