Chronic Wasting Disease
Chronic Wasting Disease (CWD) is a transmissible spongiform encephalopathy (TSE) affecting farmed and free-ranging deer, elk, and moose, in North America.CWD is a progressive, fatal, degenerative neurological disease. It was first recognized in 1967 as a clinical ‘wasting’ syndrome of unknown cause in captive mule deer in Colorado. CWD belongs to the family of diseases known as transmissible spongiform encephalopathies (TSEs). TSEs include a number of different diseases affecting animals or humans including bovine spongiform encephalopathy (BSE) in cattle, scrapie in sheep and goats, and Creutzfeldt-Jacob disease (CJD) in humans. Although CWD shares certain features with other TSEs, it is a distinct disease affecting only deer, elk, and moose.
TAHC CWD Herd Programs
The Texas Animal Health Commission (TAHC) provides a voluntary herd status program for species that are susceptible to CWD. Those that participate in the program must have a herd inventory performed annually by a TAHC, USDA, or accredited veterinarian.
