Americans dispose of millions of pounds of tons of food, and the U.S. Department of Agriculture estimates that 11.8 percent of American households, or about 15 million, had difficulty providing enough food for all their family members (Coleman-Jensen et al., 2018). Much of the food disposed into landfills is wholesome and edible. This fact sheet outlines how a potential food donor can get started and get food into the hands of the needy.
