Wildlife Agency updates CWD surveillance with over 12000 samples across Pennsylvania

The Pennsylvania Game Commission has reported significant advancements in its Chronic Wasting Disease (CWD) surveillance and management efforts during the Board of Game Commissioners meeting on April 11, 2025. As of this week, over 12,600 samples have been collected statewide, marking an increase from approximately 10,000 samples at the same time last year. Of these, 487 tested positive for CWD, primarily concentrated in Disease Management Area (DMA) 2, located in the South Central region of the state.

The commission noted that the turnaround time for results from hunter-submitted samples has improved, averaging four days, which is four days faster than the previous year. This efficiency is crucial for timely management decisions and public health communications regarding deer populations.

In response to rising CWD prevalence, the commission announced proposed expansions of several DMAs. Notably, DMA 2 in York County and DMA 3 in Armstrong County will be expanded due to positive detections from both roadkill and hunter-harvested samples. Additionally, new DMAs will be established in Luzerne and Wayne Counties, reflecting the ongoing spread of the disease.

The meeting also highlighted ongoing research into deer mortality rates in areas with high CWD prevalence. Preliminary findings indicate unusual out-of-season mortalities, prompting further investigation into the impacts of CWD on deer populations.

As the commission continues to refine its CWD management strategies, discussions are underway regarding the potential consolidation of DMAs, given their expanding boundaries. This consideration aims to enhance regulatory effectiveness and streamline management efforts across affected regions.

The Game Commission remains committed to maintaining a healthy deer population while addressing the challenges posed by CWD, ensuring that both wildlife and community interests are prioritized in their ongoing efforts.
