Chronic Wasting Disease (CWD) has been discovered in deer breeding facilities in Matagorda and Mason counties. This marks the first positive detection of the disease in these counties.
An epidemiological investigation found that both deer breeding facilities had received deer from a Uvalde County premises where CWD was found on March 29. Postmortem tissues samples were submitted by the permitted deer breeders to assist Parks and Wildlife Department and Texas Animal Health Commission (TAHC) with the epidemiological investigation.
The National Veterinary Services Laboratory (NVSL) in Ames, Iowa, has since confirmed CWD in those tissue samples.
TPWD and TAHC officials have taken immediate action to secure all cervids at the Matagorda County and Mason County deer breeding facilities and plan to conduct additional investigations for CWD. In addition, other breeding facilities and release sites that have received deer from these facilities or shipped deer to these facilities during the last five years have been contacted by TPWD and cannot move or release deer at this time.
On March 31, TPWD and TAHC reported two CWD confirmations at breeding facilities in both Hunt and Uvalde counties. The Hunt facility underwent further DNA testing to confirm animal identification and origin, and on May 12 the DNA test results confirmed the deer’s connection to the premises.
“Regrettably, the gravity of this situation continues to mount with these new CWD positive discoveries, as well as with the full understanding of just how many other facilities and release sites across Texas were connected to the CWD positive sites in Uvalde and Hunt Counties,” said Carter Smith, TPWD executive director
TPWD and TAHC continue to work together to determine the extent of the disease within all the affected facilities and evaluate risks to Texas’ free ranging deer populations. Quick detection of CWD can help mitigate the disease’s spread.
CWD was first recognized in the U.S. in 1967 and has since been documented in captive and/or free-ranging deer in 26 states and three Canadian provinces.
In Texas, the disease was first discovered in 2012 in free-ranging mule deer along a remote area of the Hueco Mountains near the Texas-New Mexico border and has since been detected in 228 captive or free-ranging cervids, including white-tailed deer, mule deer, red deer and elk in 13 Texas counties.
