The company says it will help place some affected workers who would be willing to move. It also will maintain its well-known Butterball help hotline, which employs 50 people in Naperville.

Butterball purchased the former Gusto Packing in 2013 and made improvements with financial assistance from the village.

“Gusto Packing was a long-time, family owned business and when Butterball purchased the plant and made improvements, we anticipated that they would be operating their business here for many years to come.  The employees have been very loyal to this facility for a long time, and the sudden closure comes as a shock to them and to us,” Village President Matt Brolley said in a prepared statement.
