Three more districts join big-city alliance that stresses healthy school food
School districts serving Philadelphia, Baltimore and Las Vegas joined the Urban School Food Alliance, which now serves 3.6 million students in 10 of the largest U.S. districts with a combined $735 million a year in purchases of food and supplies. The alliance launched a procurement initiative in 2014 for antibiotic-free chicken, and said this year that its members would not relax school lunch standards despite a USDA offer of flexibility on salt and whole grains.
