While a newspaper article in today’s Detroit Free Press stated a few
deer in Kent County appeared to exhibit neurological symptoms consistent
with Chronic Wasting Disease (CWD), a department of Natural Resources’
test on one deer was negative for the fatal disease, according to
wildlife officials.
“Our department is doing targeted, active CWD surveillance on deer
around the state,” said William Moritz, chief of the DNR Wildlife
Division. “If any local law enforcement agencies come into contact or
are alerted about deer that are suspect, we encourage them to dispatch
the deer and turn the carcass over to the DNR for proper testing and
analysis.”
Moritz said a DNR biologist examined another deer from the Kent
County area and concluded a vehicular accident most likely caused the
displayed symptoms. However to ensure a correct diagnosis, the animal is
currently being tested for CWD.
Since 2002, the DNR has conducted targeted CWD surveillance. Deer
examined displayed neurological symptoms consistent with CWD and were
collected by the DNR. DNR laboratory staff have physically examined and
tested 190 suspect deer and eight suspect elk. Many of those deer had
brain abscesses resulting from trauma to the head, probably from a
vehicle. As of Sept. 1, the DNR has tested 17,286 deer and 332 elk that
were submitted by hunters or killed by a vehicle. No animal in Michigan
has tested positive for CWD.
“Deer are often subject to injury and illness, and receiving reports
of unhealthy deer is not unusual,” said DNR Wildlife Veterinarian Steve
Schmitt. “Evidence of trauma to deer is not easily observed. Deer that
incur trauma associated with vehicular accidents may later become
lethargic, emaciated, drool, and become unafraid of humans. Pneumonia
does occur in wild deer and those deer often exhibit similar symptoms.”
The DNR is continuing targeted surveillance of suspect deer. Public
participation in this effort is valuable. Should a citizen observe a
deer exhibiting neurological symptoms consistent with CWD, such as
staggering, drooling or emaciation, they should contact the nearest DNR
office. It should be noted that CWD symptoms are also characteristic of
other diseases, and CWD can only be detected through an examination of
an animal’s nervous system tissues.
