FDA-iRISK is a web-based system designed to analyze data concerning microbial and chemical hazards in food and return an estimate of the resulting health burden on a population level.

The data required to execute this analysis include the food and its associated consumption data and processing/preparation methods, the hazard and its dose-response curve, and the anticipated health effects of the hazard when ingested by humans. Each of these elements contributes an essential piece of information to the model on which the final estimate of risk is based.

When you register, you will be assigned your own personal workspace in which to model food/hazard risk scenarios. You may also share this workspace with others to view. Note: your model and data are only accessible by you, unless you choose to share them with another user. FDA does not have access to your information. See privacy disclaimer via Register link below.

For a complete description, review the Quick Start Tutorial and User Guide on the Help page before beginning.
