Chronic wasting disease has spread beyond control in Illinois, forcing state officials to abandon deer culling programs after 20 years of failed containment efforts. The disease expanded from one county to over 20, with recent culls capturing only one-tenth of previous year's totals. Wildlife managers admit they no longer have sufficient resources to make a meaningful difference against this always fatal prion disease that affects deer populations nationwide.

The $22 billion hunting industry faces significant threats as CWD spreads across 36 states. Hunting license sales, equipment purchases, and related tourism could see substantial declines if consumer confidence wavers. Agricultural sectors also worry about potential transmission to livestock, recalling how mad cow disease caused industry-wide collapse and cost billions when it jumped to humans in the 1990s.
