Details:
Two other U.S. companies relying upon prison labor for products sold in their stores are K-Mart and J.C. Penny. Both sell Jeans made by inmates in Tennessee prisons. The same prison in Tennessee provides labor for Eddie Bauer’s wooden rocking horses. There are other products we would not associate with prison made products: dentures, partials, eye glasses, processed foods such as beef, chicken and pork patties sold to and served in our schools, grocery stores and hospitals.
