year, the department issued its first research bulletin on the sugar content of grape varietals and their suitability for wine. Six years later the USDA would begin its first research on animal diseases, specifically hog cholera, which was causing devastating losses at the time. In the early 1900s the USDA began analyzing food composition and the first studies of nutrition and the effects of cooking and processing foods were conducted. Finally, in 1953 the Agricultural Research Service was created to be the USDA's primary scientific research agency. Research centers ARS supports more than 2,000 scientists and post docs working on approximately 690 research projects within 15 National Programs at more than 90 research locations. The ARS is divided into 5 geographic areas: Midwest Area, Northeast Area, Pacific West Area, Plains Area, and Southeast Area. ARS has five major regional research centers: Western Regional Research Center in Albany, California Center for Agricultural Resources Research in Fort Collins, Colorado Southern Regional Research Center in New Orleans, Louisiana National Center for Agricultural Utilization Research in Peoria, Illinois Eastern Regional Research Center in Wyndmoor, Pennsylvania The research centers focus on innovation in agricultural practices, pest control, health, and nutrition among other things. Work at these facilities has given life to numerous products, processes, and technologies. ARS' Henry A. Wallace Beltsville Agricultural Research Center (BARC) in Beltsville, Maryland, is the world's largest agricultural research complex. Other D.C. area locations include the United States National Agricultural Library and the United States National Arboretum. ARS also has six major human nutrition research centers that focus on solving a wide spectrum of human nutrition questions by providing authoritative, peer-reviewed, science-based evidence. The centers are located in Arkansas, Maryland, Texas, North Dakota, Massachusetts (the Human Nutrition Research Center on Aging), and California. ARS scientists at these centers study the role of food and dietary components in human health from conception to advanced age. The ARS also offers the Culture Collection, which is the largest public collection of microorganisms in the world, containing approximately 93,000 strains of bacteria and fungi. The ARS Culture Collection is housed at the National Center for Agricultural Utilization Research (NCAUR) ARS operates the U.S. Horticultural Research Laboratory in Fort Pierce, Florida, and the U.S. National Poultry Research Center in Athens, Georgia. Other notable ARS facilities include Northern Great Basin Experimental Range in Oregon, and formerly the Plum Island Animal Disease Center off Long Island. Several
