"DHS [Department of Homeland Security] has the responsibility and national stewardship mandate for detecting, preventing, protecting against, and responding to terrorist attacks within the United States. These DHS responsibilities, as applied to the defense of animal agriculture, are shared with USDA [United States Department of Agriculture]. The interdependence of the DHS and USDA missions requires development of a coordinated strategy to adequately protect the Nation against biological threats to animal agriculture. Consultations between DHS and USDA on a coordinated biodefense strategy as called for in Homeland Security Presidential Directive 9 (HSPD-9), 'Defense of United States Agriculture and Food,' have revealed an infrastructure gap that must be filled by an integrated research, development, test, and evaluation (RDT&E) infrastructure for combating bio- and agro-terrorism threats. [...] The Plum Island Animal Disease Center (PIADC) has historically conducted much of the research that would be conducted at the NBAF [National Bio and Agro-Defense Facility]. [...] Recognizing the growing need for veterinary countermeasures to protect this Nation's agricultural sector and recognizing the limitations posed by the current PIADC facility to meet this requirement, HSPD-9, directs that the 'Secretaries of Agriculture and Homeland Security will develop a plan to provide safe, secure, and state-of-the-art agriculture biocontainment laboratories that research and develop diagnostic capabilities for foreign animal and zoonotic diseases.'"
