At first glance, the 1,800 square-foot Salvation Farms facility in Vermont seems like any other produce-packing site. But it’s part of a prison, and the nine men who cleaned and packed nearly 70,000 pounds of potatoes there last year are inmates. The food was all would-be waste, but thanks to Salvation Farms, it went to 270 food banks around the state. The program is proving valuable for the corrections department, too, providing service to the hungry while giving prisoners a productive outlet. The program has drawn support from state government officials and private donors alike.
