Chronic Wasting Disease (CWD) is a fatal neurologic disease of cervids, including mule deer (Odocoileus hemionus) and elk (Cervus canadensis). CWD has not yet been detected in California’s mule deer and elk population. To monitor California’s herds, the California Department of Fish and Wildlife (CDFW) has developed and implemented a CWD surveillance program. The program seeks to enlist the help of California’s deer hunters, meat processors, and taxidermists to monitor for CWD.This voluntary program encourages partners who harvest or handle a harvested deer from California to submit medial retropharyngeal lymph nodes (RPLN) for CWD testing.
