FD-302a (Rev. 10-6-95) 279A-WF-222936-USAMRIID Continuation of FD-302 of Bruce Edwards Ivins ,On 03/31/2005 ,Page b6 b7C Specifically, about one-half of the twenty samples he collected appeared to generate anthrax colonies when cultured. Ivins did not subject these "presumptive" positives to any confirmatory analysis. In response to these presumptive positives, Ivins said he cleaned up Hesk and left it at that. He took no further actions to decontaminate the room. When questioned as to why he took no remedial measures beyond cleaning up desk, Ivins advised that he did not consider the level of contamination indicated by his sampling to be significant, stating that he did not find "hundreds or thousands" of spores but only a "few presumptives." Ivins said he did not believe a full decontamination of the room was warranted based on his findings, and he did not perceive himself or his office mates to be in any danger. Iyins confirmed that he did not tell About his swabbing of. workspace nor did he advise lof the presumptive positive results. IviNs did tell about his findings. He did not suggest to either co-worker that antibiotic prophylaxis might be appropriate. IviNs again reiterated that based on the level of contamination he observed, he did not perceive himself or his coworkers to be at risk. Ivins confirmed that he undertook the collection of environmental samples from his office space on his own initiative. and without any prior authorization from superiors. When queried as to why he did not seek permission to swab or voice his concerns. about the possible contamination to UsAMRIID's or others, Ivins predicted that would have. been dismissive of his concerns and would have told him to "forget. about : IVINs related that angry reaction when learned_of Ivins' environmental sampling confirmed Ivins' suspicions that would be opposed to such swabbing. IVINS opined that despite his outward response, inwardly seemed "sort of pleased" with Ivins' finding of contamination because it allowed to "point a finger" at for poor laboratory safety procedures. Ivins also re-emphasized that there was a longstanding political rivalry between DsD and the Bacteriology Division. b2 b7F According to Ivins, Bacteriology Division employees felt somewhat ostracized and belittled by DsD researchers who were reportedly Bacteriology employees' superior expertise. The path IvinS chose to swab was the path that the Daschle letter took from to paaangaq SniaI :Eg aagns Jo Tnem aya ut xoq-ssed aya ybnoiya pue
