In response to the discovery of a BSE-infected cow in Washington State in December 2003, the U.S. Department of Agriculture (USDA) Food Safety Inspection Service (FSIS) commissioned the Harvard Center for Risk Analysis (HCRA) to use the Harvard Bovine Spongiform Encephelopathy (BSE) simulation model to investigate the impact of alternative measures to mitigate exposure of the human population to the BSE agent. FSIS released the HCRA analysis in October 2005 and presented the findings of that analysis at a technical meeting open to the public in July 2006. FSIS subsequently received public comments on the HCRA analysis. As part of its response to those public comments, FSIS contracted for further analysis using the Harvard BSE simulation model. This report describes those analyses.
