Exploring public perception to chronic wasting disease in Missouri's deer population
Abstract
[EMBARGOED UNTIL 08/01/2026] Chronic Wasting Disease (CWD) is a transmissible spongiform encephalopathy that affects cervids and has sparked ongoing controversy surrounding its management. Many strategies used to control the spread of CWD, such as targeted removal, baiting restrictions, and mandatory sampling, can directly impact hunters. These impacts often lead to negative perceptions of management efforts. This study aimed to evaluate public perceptions of CWD management across Missouri, with a focus on comparing responses from hunters and non-hunters. A mixed-methods approach was used, including a randomized mailing of 2,500 surveys distributed statewide and an online version shared via social media. Survey responses were analyzed using Kruskal-Wallis and Chi-Square tests. Each distribution method was first analyzed separately, then combined to assess overall trends and differences between methods. Findings revealed that most participants acknowledged CWD as a legitimate issue but expressed varying levels of trust and support for current management strategies. Hunters tended to report greater knowledge of CWD but were more skeptical of wildlife agencies and less supportive of certain mitigation efforts. Non-hunters, by contrast, were more neutral or supportive. Participants recruited via social media were generally more critical of CWD management than those from the mailed sample. Despite these differences, respondents across both platforms agreed that hunters have a role to play in slowing the disease's spread. This study highlights the importance of public trust and clear communication in wildlife disease management. Misinformation and a lack of understanding can erode support for science-based strategies. Efforts to improve transparency and public education, especially among stakeholder groups most affected by CWD policies, may help shift perceptions and increase cooperation with management efforts.
