Sandra HoffmannSenior Economist
Sandra (Sandy) Hoffmann is a senior economist with USDA's Economic Research Service, Food Economics Division, Diet, Health, and Safety Economics Branch. Her research focuses on food safety, valuation of the health benefits of public policies, and integration of economic analysis and risk assessment. She is recognized for her research on the cost of foodborne illness, attribution of foodborne illness to its food sources, and children's environmental health. Sandy served on the National Academy of Sciences (NAS) committee on the Effectiveness of National Biosurveillance Systems. She was a commissioned scientist on the World Health Organization’s Global Burden of Foodborne Disease Initiative. Sandy has served on advisory panels to the UK Food Standards Agency and Food Standards Australia New Zealand on health valuation. She has also advised the Organization for Economic Cooperation and Development (OECD) and the Environmental Protection Agency (EPA) on valuation of children's benefits from environmental health programs. She serves on the board of the Society for Risk Analysis and on the editorial board of the Journal of Agricultural and Applied Economics.

- Global Food Safety—How changes in income and food prices could affect the global burden of foodborne disease; and estimating the social cost of deaths from foodborne disease globally.
Prior to joining ERS in 2010, Sandy was a Research Fellow at Resources for the Future (2000-2010) and a faculty member at the University of Wisconsin-Madison (1999-2000). She also practiced pesticide and chemical manufacture regulatory law (1986-1989) and served with the U.S. Peace Corps in rural Chile (1980-1982).
Sandy holds a Ph.D. from the Department of Agricultural and Resource Economics, University of California, Berkeley and an M.A. in agricultural economics from the University of Wisconsin-Madison. She also received a J.D. from the University of Michigan Law School and her B.S. from Iowa State University.
Sandy is a member of the Agriculture and Applied Economics Association (AAEA), the International Association for Food Protection (IAFP), the Society for Risk Analysis (SRA), the Society for Benefit Cost Analysis (SBCA), and the Association of Environmental and Resource Economists (AERE).
