; (B) the dosage and infection rates for each such pathway and mechanism; and (C) the relative frequency of each mode of such transmission; (2) identify anthropogenic and environmental factors contributing to new chronic wasting disease emergence events, the development of geographic areas with increased chronic wasting disease prevalence, and overall geographic patterns of chronic wasting disease distribution; (3) identify significant gaps in current scientific knowledge regarding the transmission pathways identified under paragraph (1); (4) identify and prioritize scientific research projects that will address the knowledge gaps referred to in paragraph (3); and (5) review science-based best practices, standards, and guidance regarding the management of chronic wasting disease in wild, captive, and farmed cervid populations in the United States which have been developed by— (A) the National Chronic Wasting Disease Herd Certification Program referred to in section 2(3); and (B) State wildlife and agricultural agencies, which provide practical, science-based recommendations to State and Federal agencies for minimizing or eliminating the risk of transmission of chronic wasting disease in the United States. (d) Report Not later than 6 months after the date on which funds are first made available for the study under subsection (a), the Secretary shall submit to the Committee on Agriculture of the House of Representatives and the Committee on Agriculture, Nutrition, and Forestry of the Senate a report that describes— (1) the findings of the study; and (2) any conclusions and recommendations that the Secretary determines to be appropriate. 4. Definitions In this Act: (1) Chronic wasting disease The term chronic wasting disease means the animal disease afflicting deer, elk, and moose populations that— (A) is a transmissible disease of the nervous system resulting in distinctive lesions in the brain
