The York County Commissioners have launched a joint venture with a broad coalition of nonprofits to replace assistance to food-insecure families lost when York County Food Rescue abruptly shut down last month. “There is a real need in this community for this partnership,” Sallie Chandler, chairwoman of the commissioners, said in a news release Friday. The group, Partners for a Hunger-Free York County, will occupy the same county-owned space as the former Food Rescue and support a wide array of food-related programs for county residents.
