SB 2843 directs the Texas Parks and Wildlife Department (TPWD), in collaboration with three major state research institutions — the Texas A&M College of Veterinary Medicine, the Texas Tech University School of Veterinary Medicine, and the University of Texas Southwestern Medical Center — to conduct a comprehensive study of Chronic Wasting Disease (CWD) management in Texas. CWD is a fatal, transmissible neurological disease affecting deer and other cervids. This legislation seeks to assess the effectiveness of TPWD's current rules and policies in containing the disease and to explore the genetic resistance of various cervid populations to CWD.
The study must include a comparative analysis between Texas' disease management approaches and those used by other states, a review of the benefits and deficiencies in existing Texas regulations, and a scientific analysis of cervid genotypes for CWD resistance. Public input is a required component of the study: the department must hold a public hearing and maintain an online portal open for at least 60 days to collect public comments. Additionally, TPWD must provide responses to all comments submitted.
The final report is due by December 1, 2026, and will be provided to the Governor, the Lieutenant Governor, the Speaker of the House, TPWD leadership, and key legislative committees. Importantly, the bill mandates that the study and report be carried out using existing resources, ensuring no additional taxpayer burden. The bill takes effect on September 1, 2025, and expires on May 31, 2027, preventing it from establishing any ongoing new government program or permanent regulation.
The originally filed version of SB 2843 directed the Texas Parks and Wildlife Department (TPWD) alone to conduct a study evaluating the effectiveness of its rules and policies related to the management of Chronic Wasting Disease (CWD) in cervids. This version of the bill placed the full responsibility for the study on the agency itself, utilizing existing resources. It also required a public hearing and a 60-day online comment period, with a mandate that the department respond to public comments. The study was to include a comparative analysis of Texas rules with those of other states, an evaluation of cervid genetic resistance to CWD, and incorporation of relevant scientific and statistical data.
The Committee Substitute keeps the core framework intact but introduces an important enhancement: it assigns the study to a collaborative effort between TPWD and three prominent academic institutions — Texas A&M, Texas Tech University School of Veterinary Medicine, and the UT Southwestern Medical Center’s Peter O'Donnell Jr. Brain Institute. By doing so, the substitute broadens the scientific rigor and independence of the study, ensuring that external experts in veterinary medicine and neuroscience contribute to the assessment.
Additionally, while the public input process remains essentially the same, the substitute refines the language around public comment procedures to clarify expectations. Structurally, the Committee Substitute is more deliberate in mandating a comparative analysis with other states' CWD policies and emphasizes both the benefits and deficiencies of Texas’ existing approach. Overall, the Committee Substitute transforms the bill from an internal agency review to a more transparent, academically robust study without expanding its cost, scope, or timeline.
