Chronic Wasting Disease Threatens Florida’s Deer Population

As of November 11, 2025, Florida wildlife officials are increasingly concerned about the potential spread of Chronic Wasting Disease (CWD), a fatal neurological disease affecting cervids – deer, elk, moose, and caribou. The disease poses significant ecological, economic, and social challenges to the state.
What is Chronic Wasting Disease?
Chronic Wasting Disease (CWD) is a progressive, fatal neurological disease affecting cervids. Unlike diseases caused by bacteria or viruses, CWD is caused by misfolded proteins called prions. these prions accumulate in the brain, spinal cord, and other tissues, creating microscopic holes and ultimately leading to nerve cell damage and death. According to the United States Department of Agriculture (USDA), CWD is always fatal to infected animals.
The disease has a long incubation period, typically 16 to 36 months, during which infected animals show no outward symptoms but can still transmit the disease to others. This silent spread makes CWD particularly difficult to control.
The Threat to Florida
While CWD has not been widely detected in Florida as of November 2025, its presence in neighboring states raises significant concerns. The Florida fish and Wildlife Conservation Commission (FWC) is actively monitoring the state’s deer population and implementing preventative measures. The FWC’s CWD response plan, updated in October 2024, outlines strategies for surveillance, prevention, and potential management of the disease.
Florida’s white-tailed deer population is estimated at 700,000, with approximately 100,000 harvested by hunters annually, making them the state’s most popular game animal. Biologist Steven Shea, who manages over half a million acres of wildlife habitat in Central Florida, warns of a potential “domino effect” if CWD becomes established. He emphasizes that hunters are a crucial first line of defense, as each submitted sample aids in tracking the disease’s spread.
The economic impact of CWD could be substantial, affecting recreational hunting, tourism, and the broader agricultural industry. Beyond the economic concerns, CWD poses a threat to Florida’s biodiversity and the health of its ecosystems.
How CWD Spreads
CWD spreads through direct contact between deer or through an environment contaminated with infectious materials. Key routes of transmission include:
- Urine and feces of infected animals
- Saliva and blood
- Contaminated soil and water sources
- Movement of infected live cervids
The USDA notes that prions can persist in the environment for years, making eradication extremely challenging. USDA CWD Basics
Human Health Concerns
Currently, there is no evidence that CWD can infect humans. However,health organizations,including the Centers for Disease Control and Prevention (CDC), recommend taking precautions. These include:
- Avoiding consumption of meat from deer that appear sick or have tested positive for CWD
