The state had recently announced the first detections in two other counties, including one that neighbors the newly affected location.
CWD had recently been detected about 100 miles from the newly affected area.
Following the state's first detection in 2018, CWD has now been found in 17 counties.
The center also works to address other protein-misfolding disorders such as Alzheimer's and Parkinson's diseases and amyotrophic lateral sclerosis.
The buck, which carried a GPS tracker, died in the middle of October.
This case will likely be managed differently than the 2021 detection because of migration patterns, officials said.
The farm is in quarantine with an investigation underway.
In other CWD developments, Minnesota's agriculture department released safety tips for meat processors who handle deer.
The deer, found in the north-central lower peninsula, showed symptoms including wasting, drooling, and lack of fear of people.
Such actions include boosting research capacity, expanding hunting seasons, offering more hunting permits, and restricting baiting.
