Ivins also reported that he had no concerns about competency as a land his decision to. Swab work area was not influenced by any perception that was negligent in. safety practices. Ivins was also questioned concerning information he concerning his unilateral decision to collect environmental samples (swabs) from areas associated with Suite B3 in Building 1425 in April 2oo2. Ivins advised that he made the decision to unilaterally swab areas associated with Syite B3 when he learned that USAMRIID researcher had recently conducted an. environmental sampling of the B3 lab which produced several. presumptive positives for Bacillus anthracis. reportedly undertook this sampling effort in response to a suspected spill which occurred durinq an experiment being conducted by researchers. As a precautionary measure, nasal swabs were taken from In addition to the possible spill and. nasal swab, Ivins also recalled that Suite B3 is where he had conducted plating and colony counts on the Daschle letter. Consequently, he suspected that stray spores may have aerosolized during that effort. Ivins advised that the December 2001 and April 2002 environmental samplings represent the only two times he has ever swabbed in the cold areas of usAmRiiD outside of the hot suites. Ivins related that during the early l99os he performed a lot of swabbing inside the hot suites as part of usAmRIiD's routine environmental monitoring program. He conducted this sampling at the direction of his superiors. These samples were collected as a routine safety precaution and, unlike his December 2ool and April 2002 collections, were not performed in response to a specific concern or suspected contamination. IviNs has since been excluded from the task of any such monitoring. IvIns reported that no isolates related to his December. 200l or April 2002 swabbing initiatives remain in existence.
