The
Foodborne Illness Risk Ranking Model
The Foodborne Illness Risk Ranking Model (FIRRM) is a decision tool used to examine the public health burden of foodborne illnesses due to microbiological hazards from specific food commodities. Users can rank pathogen-food combinations by different measures of annual disease burden, including estimated cases, hospitalizations, and deaths, as well as by estimated costs of illness and QALY loss. FIRRM is an open model designed in Analytica, a Monte Carlo simulation environment with a visual interface built on functional influence diagrams. Due to the visual programming nature of Analytica, much of the model documentation is built directly into the model itself. Instructions for installing Analytica and downloading the model can be found at the bottom of this page.
Project Collaborators and Contacts
The model was developed by a multidisciplinary team from Resources for the Future, University of Maryland School of Medicine and Iowa State University.
Funding and Timeline
Funding for the development of FIRRM was made possible by a grant from The Robert Wood Johnson Foundation. The model was developed over a fifteen-month period and culminated with a conference in September 2003.

Expert Elicitation Survey
For this project, we asked experts on
foodborne illness to attribute, for 11 pathogens, the attributable fraction
of illnesses due to specific food vehicles. This document is a copy of this
survey. More information about the survey can be found in FSRC Discussion
Paper 01, available above.
Events
-
Conference on the Risk Ranking Model
The FSRC held a one day conference on preliminary results from FIRRM on September 12, 2003. This conference page includes the agenda, background materials, and audio/visual recordings of the event, including a demonstration of the model. -
Workshop Series:
Prioritizing Opportunities
to Reduce Foodborne Risk
The FSRC is holding a series of three workshops to develop a conceptual framework for prioritizing opportunities to reduce risk based on an understanding of the integrated and systems-wide approach necessary to reduce foodborne illness.
