A midwestern food-processing giant will help food banks nationwide, including some in Iowa. Con-Agra’s giving 31 refrigerated trucks to food banks, something that’s always on their wish list according to Lynn Phares.They need to move food from donors to the hungry and always need trucks. Phares heads Con-Agra’s “Feeding Children Better” Foundation. She says the deal got better because of some dot-com busts recently that put online order-filling firms out of business.A couple of former dot-commers “WebVan” and “Home Grocer” had slightly used trucks for sale, and ConAgra’s foundation is committed to buying trucks for about half the food banks in the U-S. The gift will benefit food banks in Waterloo and Sioux City, Iowa.
