KINCHELOE, Mich. (WWJ/AP) – An official says inmates at a second prison in Michigan’s Upper Peninsula have participated in a peaceful protest over the quality of food provided by a state contractor.

Michigan Department of Corrections spokesman Chris Gautz says demonstrations at Chippewa Correctional Facility took place Saturday through Monday. They followed protests March 20-21 at Kinross Correctional Facility, another Kincheloe-area prison.

Gautz told the Detroit Free Press that food and other issues were the subject of the protest at Chippewa. He says nearly all prisoners in one wing refused to show up for meals.

“It’s definitely something the facilities took seriously,” Gautz told the newspaper. “It is unusual in a high school or a prison, because there are different groups or cliques that form, to have everybody on the same page. It takes some coordination.”

Oldsmar, Florida-based Trinity Services Group replaced Philadelphia-based Aramark Correctional Services as Michigan’s prison food contractor last year.

An email Thursday seeking comment from a Trinity spokesman was not immediately returned.
