check markIndicates Completed Project

Risk Assessments

Evaluate relative effectiveness of control strategies to reduce or prevent foodborne illnesses. Serve as tools for informed policy decisions and for use by public-health officials, food industry, etc.

Risk Profiles

Comprehensive review of scientific data and information to identify and evaluate potential control and prevention options.

  • Hepatitis A Virus in Produce
  • Transmission of Norovirus
  • Listeria in Fresh Produce
  • Pathogens in Raw-Milk Cheese
  • Pathogens and Filth in Spices



Work with others to leverage resources, to improve the utility and capability of risk assessments.

  • Scientific Assessment and Evaluation Contract (RTI): Support development of farm-to-table risk tools.
  • GIS Modeling and Risk Assessment Tools: (IAG w/NASA, ARS, APHIS): Development of model to characterize and predict contamination of produce with enteric pathogens.
  • The Interagency Risk Assessment Consortium (IRAC): Enhance communication and coordination among Federal agencies and conduct of scientific research to facilitate risk assessments.
  • JIFSAN Steering Committee: facilitate education efforts on risk assessment, including content for www.foodrisk.org disclaimer icon , an information hub for the greater risk-assessment community.
  • Peer Review Contract (Versar, Inc.): independent external peer review of scientific information and risk assessments.
  • Wildlife and livestock database (w/APHIS).


Research & Data Collections

Provides information and data for planned or ongoing risk profiles and assessments, including development of new tools and methods.
