Pesticide News Story: Dietary Exposure Model Software Available for Testing

For Release: October 21, 2011

EPA is making a beta version of the Dietary Exposure Evaluation Model-Food Commodity Intake Database freely available to the public for testing. DEEM-FCID is a dietary exposure analysis system for performing chronic and acute exposure assessments. This beta version is not intended for regulatory purposes at this time, but is instead being released as an evaluation version for public testing and review. At present, the agency will continue to use its current version of DEEM-FCID (v 2.03) to conduct dietary risk assessments for estimating exposure and establishing pesticide tolerances. The beta version of DEEM-FCID being released for public testing and evaluation contains more recent food commodity consumption data derived from the National Health and Nutrition Examination Survey for 2003-2006 in place of the USDA Continuing Survey of Food Intake by Individuals, 1994-96/1998 data that is currently used in dietary assessments.

DEEM-FCID can be used to estimate dietary intake of toxicants, nutrients, pesticides, food additives and natural constituents – in short for any component of food or water. EPA is able to use this beta version of the software to look at exposures at each eating occasion rather than considering the entire day’s food and drink intake at once. This will allow EPA to make more refined risk assessments where appropriate.

We are interested in your feedback on the beta version of this software containing updated dietary consumption data and additional features, so a message board will be set up for beta-users to comment. Discussions will help us refine the usability of the software for later final release to the public which is expected in spring 2012.
