Louisiana Reports First Chronic Wasting Disease Detection in Hunting Season

The Louisiana Legislature convened on September 4, 2025, to address ongoing concerns regarding Chronic Wasting Disease (CWD) in deer populations. The meeting focused on recent findings, public health implications, and management strategies related to the disease.

The discussion began with a report on a specific case involving a 4.5-year-old buck that displayed symptoms consistent with CWD. A hunter encountered the deer, which did not react to his presence, prompting him to dispatch the animal and contact local biologists. Samples were collected for testing, as it is crucial to determine the cause of death in deer exhibiting such symptoms. Historically, many deer tested have shown alternative causes for their condition, such as brain abscesses. However, this particular case confirmed the presence of CWD, marking a significant detection in Tensas Parish.

Since the initial detection, Louisiana has recorded a total of 40 cases of CWD, with eight involving deer that exhibited symptoms. Notably, most positive cases have been found in hunter-harvested deer that appeared healthy, indicating that the disease can be present without visible signs. This has led to a proactive approach among hunters, who are encouraged to submit their deer for testing. The speaker emphasized the importance of this initiative, stating that it is better to know about the disease than to remain in denial.

The meeting also highlighted the immediate response following the detection of CWD, including the implementation of a feed ban to prevent potential spread. This ban was enacted through a declaration of emergency, although there is typically a brief administrative lag before such measures take effect. The speaker noted that this prompt action may have contributed to limiting the disease's spread within the state.

In conclusion, the meeting underscored the importance of public awareness and participation in CWD testing among hunters. The proactive measures taken by the Louisiana Department of Wildlife and Fisheries aim to manage and contain the disease effectively, ensuring the health of both deer populations and public safety. Further monitoring and testing will continue as part of the state's ongoing efforts to combat CWD.
