DEEM-FCID/Calendex Software Installer

DEEM-FCID/Calendex Version 3.18/9.14 Release

The EPA originally made the Dietary Exposure Evaluation Model - Food Commodity Intake Database (DEEM-FCID)/Calendex v. 3.14/9.13 freely available to the public in June 2012. The public availability of this model helps increase transparency of regulatory decisions. This notice announces an update to this version, DEEM-FCID/Calendex v.3.18/9.14. While this update does not incorporate new consumption data, it does fix several minor issues and bugs that have been identified since the DEEM-FCID/Calendex software was first released to the public in June 2012. The user should refer to the DEEM Release History and Errata List (PDF) (7 pp, 109k) document which provides information on changes and fixes since the June 2012 release. These issues have been in most cases fully resolved and are expected to have no or only minimal impact on any typical or more routine assessment done with the earlier June 2012 version of DEEM-FCID/Calendex: minor impacts might be seen for assessments for which advanced features of DEEM or Calendex are used. For example, most of the issues identified were associated with assessments using the new ½ life module –- but would only potentially impact an assessment if there were thousands of individual residue data points in DEEM.

Because the modifications to DEEM-FCID/Calendex only affect for the most part the new advanced features of DEEM which are not frequently or typically used for the vast majority of assessments, EPA will continue to accept submissions using the earlier June 2012 release (v. 3.14) until at least late summer 2013 when a version of DEEM-FCID/Calendex which incorporates the newest 2009-2010 NHANES/WWEIA dietary consumption data is expected to be released.

DEEM-FCID/Calendex

DEEM-FCID/Calendex software incorporates food consumption data from the National Health and Nutrition Examination Survey)/“What We Eat in America” (NHANES/WWEIA) dietary survey for the years 2003-2008. This version of the software – with its use of the newer NHANES/WWEIA dietary data rather than the USDA CSFII (Continuing Survey of Food Intake by Individuals, 1994-96/1998) data – will continue to be used for regulatory risk assessments and supersedes the DEEM/Calendex version that the agency has been using (version 2.02), which was based on the CSFII 1994-96/1998 data.

The DEEM-FCID component of DEEM-FCID/Calendex can be used to estimate dietary intake of toxicants, pesticides, and natural constituents – in other words for any component of food or water – to perform chronic and acute exposure assessments. The Agency uses the DEEM-FCID component to conduct dietary risk assessments to support the establishment of tolerances for residues of pesticides in/on raw agricultural commodities. In addition to containing more recent consumption data, the new publically available version of this software allows the Agency to look at exposures at each eating occasion rather than grouping the entire day’s food and drink intake at once. The Agency can thus conduct more refined risk assessments that will help inform regulatory decisions for pesticides.

The Calendex component of DEEM-FCID/Calendex employs a calendar-based approach to evaluating multi-pathway exposures. DEEM-FCID/Calendex can evaluate exposure to chemicals resulting from residues in food or drinking water, and residues in or around the residence. Similar to DEEM-FCID, Calendex uses a probabilistic (Monte-Carlo) based approach to evaluate the distribution of exposure in a way that appropriately combines exposure pathways.

EPA is also announcing at this time an update of the DEEM Quick Guide User's Manual (PDF) (24 pp, 674k) which provides a brief overview of and instructional guide to using the DEEM software. The manual has been updated from the June 2012 release to include current screenshots of DEEM. The screenshots and options appearing in this “mini-manual” now fully match those that are in the version of DEEM that is downloadable from this site.

As an additional effort to increase the transparency and public availability of dietary exposure software, the U.S. Department of Agriculture (USDA) and the U.S. Food and Drug Administration (FDA) funded the Joint Institute of Food Safety and Nutrition (JIFSAN) at the University of Maryland to post on their FoodRisk.org website's Food and Commodity Intake Database - What We Eat in America web page the consumption, recipe, and associated demographic data files used by DEEM-FCID/Calendex where these raw data files are available for download. Exit EPA disclaimer With this release of the updated version of DEEM-FCID/Calendex, the JIFSAN FoodRisk.org website has also been updated and now includes the 2003-2008 FCID data files that were incorporated into DEEM-FCID/Calendex. In addition, JIFSAN has developed several online applications to ease the process by which information from the raw data files can be accessed and interpreted by the general public, including the release of a consumption calculator which considerably simplifies the use of the data for routine food and food commodity consumption queries. A FAQ list has also been made available which describes the data and information available on the JIFSAN foodrisk.org website as well as the history of, sources for, and background behind EPA’s development of FCID for dietary exposure assessment purposes.

We also note that as a follow-up to the July 2010 Scientific Advisory Panel (SAP) meeting in which SHEDS (Stochastic Human Exposure and Dose Simulator)-Multimedia version 3 was reviewed, EPA's Office of Research and Development (ORD) released version 4 of the SHEDS-Multimedia model on its website in June 2012. SHEDS-Multimedia is a physically-based probabilistic model that can simulate cumulative (multiple chemicals) or aggregate (single chemical) exposures over time for a population via residential and dietary routes of exposure for a variety of multimedia, multipathway environmental chemicals. SHEDS uses NHANES/WWEIA 2003-2006 data. Like DEEM-FCID/Calendex, the SHEDS model produces a distribution of estimated exposures for use in exposure and risk assessment, but has more advanced capabilities with respect to analysis and output. SHEDS-Multimedia materials (including residential and dietary module codes, graphical user interfaces, technical manuals, user guides, related publications and presentations, and external peer review information) can be accessed via ORD's SHEDS-Multimedia web page.

DEEM-FCID Installation Process

The DEEM-FCID/Calendex software is intended to be downloaded and run from a personal computer. Follow the instructions below to install the software onto your PC. Note that the setup and the files are the same as the June 2012 released program (DEEM ver. 3.14). The version numbers for this release of DEEM and Calendex executable files are 3.18 for acute DEEM and 9.14 for Calendex.

  1. Download the EPA_MODEL_WWEIAFCID.zip installation zip file (50 MB, zip file) [NOTE: DEEM-FCID is included in this download]
  2. Open the EPA_MODEL_WWEIAFCID.zip file to extract or unzip the files onto "C:\Program Files\".
