CONCORDIA PARISH, La. – An animal at a deer farm in Concordia Parish has tested positive for Chronic Wasting Disease.
The confirmed case of CWD was announced this week by Louisiana officials, who said three cases of CWD were confirmed at deer farms in Concordia, Tangipahoa and St. Landry parishes.
The announcement came after an active case of CWD was confirmed in Jefferson Davis Parish in December 2025.
These farms, which also participate in the state deer program, have been issued a quarantine restricting movement into or out of the facility, including live deer or deer products.
According to the USDA, a 2-year-old female deer tested positive for CWD on Dec. 11, 2025, at the Concordia Parish farm. The animal is one of a hunting herd of 60 deer that have since been quarantined.
Chronic Wasting Disease is a 100 percent always fatal disease in deer caused by an infectious prion in the Cervidae family. Prions are misfolded proteins. CWD prions are often spread by infected deer through bodily fluids.
