The U.S. Department of Agriculture was established in 1862 as a commission and later became a cabinet-level agency. It administers programs related to agriculture, nutrition, rural development, forestry, rural utilities, and research. This guide lists the major divisions, offices, and programs within USDA, but it does not include all of the agencies and offices that have been part of USDA throughout its history.

The United States Department of Agriculture is made up of numerous individual agencies and publishes thousands of resources per year.
Use this LibGuide to find resources from the various agencies that make up the United States Department of Agriculture.
The Agricultural Research Service (ARS) is the U.S. Department of Agriculture's chief scientific in-house research agency. Our job is finding solutions to agricultural problems that affect Americans every day from field to table. Here are a few numbers to illustrate the scope of our organization:

ARS research is organized into National Programs. These programs serve to bring coordination, communication, and empowerment to approximately 690 research projects carried out by ARS. The National Programs focus on the relevance, impact, and quality of ARS research.

The Animal and Plant Health Inspection Service (est. 1972) is a multi-faceted Agency with a broad mission area that includes protecting and promoting U.S. agricultural health, regulating genetically engineered organisms, administering the Animal Welfare Act and carrying out wildlife damage management activities. These efforts support the overall mission of USDA, which is to protect and promote food, agriculture, natural resources and related issues.
The Center for Nutrition Policy and Promotion (CNPP) was created within the U.S. Department of Agriculture in 1994. Together with the Food and Nutrition Service (FNS), CNPP reports to the Office of the Under Secretary for Food, Nutrition and Consumer Services. CNPP’s mission is to improve the health of Americans by developing and promoting dietary guidance that links scientific research to the nutrition needs of consumers.
The staff at CNPP is composed primarily of nutritionists who specialize in nutrition science, analytics, nutrition evaluation, education and communication – many of whom are Registered Dietitians. We also have economists, public health experts, policy advisors, graphic designers and librarians.
CNPP carries out its mission to improve the health of Americans by (1) serving as the Federal authority on evidence-based food, nutrition and economic analyses to inform policy and programs; (2) translating science into actionable food and nutrition guidance for all Americans; and (3) leading national communication initiatives that apply science-based messages to advance consumers’ dietary and economic knowledge and behaviors.

The Food & Nutrition Service (FNS), established in 1969, administers food and nutrition programs in the U.S. It is best known for the Supplemental Nutrition Assistance Program (SNAP, formerly known as food stamps), the National School Lunch Program, and Women, Infants and Children (WIC).
Evidence-based analysis and rigorous evaluation are critical tools to promote effective policies and strong management in the Federal nutrition assistance programs. The Office of Policy Support (OPS) leads the development and execution of FNS's study and evaluation agenda. This web page is intended to provide access to OPS's work to program partners, other stakeholders, and the general public.

One Team, One Purpose—Protecting Public Health and Preventing Foodborne Illness
FSIS' agency mission book, One Team, One Purpose—Protecting Public Health and Preventing Foodborne Illness (January 2014) provides a brief overview of how the agency works to lower the incidence of pathogens that cause foodborne illness and limit the occurrence of outbreaks in our regulated products.
Learn what type of data FSIS collects, what type of analyses are performed using the data, and how these analyses are used in performance management and strategic planning. Includes annual sampling plans and Public Health Regulations (PHR).
Data files; establishment-specific data; sample datasets and corresponding data dictionaries.
FoodNet is a collaborative project among FSIS, CDC, and FDA to identify, control, and prevent foodborne disease hazards. FoodNet uses sentinel sites in various states to provide more stable and accurate national estimates of the burden and sources of specific foodborne diseases.

The USDA's National Agricultural Statistics Service (NASS) conducts hundreds of surveys every year and prepares reports covering virtually every aspect of U.S. agriculture. Production and supplies of food and fiber, prices paid and received by farmers, farm labor and wages, farm finances, chemical use, and changes in the demographics of U.S. producers are only a few examples.
NASS is committed to providing timely, accurate, and useful statistics in service to U.S. agriculture. To uphold our continuing commitment, NASS will:
