The Child and Adult Care Food Program (CACFP) is a type of United States federal assistance provided by the Food and Nutrition Service (FNS) of the United States Department of Agriculture (USDA) to states in order to provide a daily subsidized food service for an estimated 3.3 million children and 120,000 elderly or mentally or physically impaired adults[1] in non-residential, day-care settings. It is a branch within the Policy and Program Development Division of the Child nutrition programs, along with the School Programs Branch, which runs the National School Lunch Program.[2] The program is commonly referred to as the Child Care, Child Care Food, Adult Care, or Adult Care Food Program, and is often operating in conjunction with other child and adult day-care programs, such as the Head Start. Its federal identification number, or CFDA number, is 10.558.[2] Section 17 of the National School Lunch Act, and USDA issues the program regulations under 7 CFR part 226.[3]
