TON CONTAINED FRE IS UNCLASSIFIED FD-302 (Rev. 10-6-95) et ° DATE le-O09-2009 BY 60324 UC BAW/RS/ LSC -1- FEDERAL BUREAU OF INVESTIGATION Date of transcription 02/16/2005 On February 2, 2005, _BRUCE WARD IVINS left a voice bé mail message for Supervisory Special Agent (SSA) b7c of the Federal Bureau of Investigation as follow-up to a matter discussed in an interview of IVINS on January 13, 2005. IVINS provided the following information: After reviewing the shipping form for the Bacillus anthracis Ames strain samples he sent to Dugway Proving Ground in 1997, IVINS believes the tubes he sent were samples of _ mixed batch of spores prepared by IVINS and The reason he believes this to be true is that the shipping form indicates the samples were spores in liquid form, unfrozen. The only Ames spores IVINS had unfrozen in liquid form in his laboratory at that time were the spores known as RMR 1030. Also, he compared the concentration of spores in the shipment to the concentration of samples he had in his laboratory at the time of the shipment. The documented concentration for RMR 1030 closely matched that on the shipping form for the spores sent as seed stock to Dugway for the mass production of spores to be used in aerosol challenge studies. On a separate issue, IVINS verified that he found RMR 1029 to be 2.4 x 10*° colony forming units (CFU) per milliliter (ml) and not 2.4 x 10° CFU/ml after it was returned to him from FBI custody. IVINS said that the viability was only down 20- 30%, not 90%, and that they were able to fix the problem b adding more spores for the aerosol challenge for Investigation on 02/02/2005 a Tyson's Corner, Virginia (telephonically) File # 279A-WF-222936- Date dictated N/A ‘\ ~ SO) bse by SSA ; ; b7c This document contains neither recommendations nor conclusions of the FBI.
