Chronic wasting disease control program results for 2011-2012

By Douglas R. Dufford District Wildlife Biologist, Illinois Department of Natural Resources Chronic wasting disease (CWD) is a fatal disease of deer, elk and moose. It does not appear to be a human health threat, though disease experts caution against eating venison from deer known to be infected.

First observed in the 1960s in captive deer in Colorado, CWD is now a very real and serious threat to wild deer throughout North America. During the past 15 years, the known range of the disease has increased dramatically (at least 17 states and two Canadian provinces have now documented CWD), and the rate of CWD infection appears to be increasing throughout much of that range. One of the most dramatic examples of the potential of CWD comes from southeastern Wyoming, where more than 50 percent of tested mule deer in the South Converse Hunting Unit (1,224 square miles) had CWD during the 2011 hunting season, compared to only 15 percent in 2001. Unfortunately, CWD is present in northern Illinois. The first case was found in a white-tailed deer near Roscoe, Ill., in 2002. Through June 30, 2012, the Illinois Department of Natural Resources (IDNR) tested more than 65,000 deer statewide and identified 372 individual deer infected with CWD. These were in 10 northern Illinois counties — Boone, Winnebago, DeKalb, McHenry, Kane, Grundy, LaSalle, Ogle, Stephenson and Jo Daviess. The highest concentration of CWD cases have been found along the Boone-Winnebago county line from Wisconsin down into northwestern DeKalb County.

Shortly after the first case was discovered, the IDNR implemented a CWD Management Program. The goals are to suppress CWD prevalence rates so they remain low, and to slow the rate of spread to the remainder of the state by reducing deer densities in CWD infection areas and maintaining deer herds at lower levels. Lower densities and the removal of CWD-positive deer reduce contact rates between sick and susceptible individuals. Deer densities are managed at the county level in the CWD area through liberal hunting regulations, including virtually unlimited numbers of firearm deer permits and the addition of a special CWD deer hunting season. Where needed, IDNR supplements hunter harvest with agency sharpshooting performed after the hunting seasons to allow for a focused removal of deer from specific areas where the disease is known to occur.

All sharpshooting is performed with landowner permission only in areas where it is safe to do so; all deer are retrieved and tested; and all venison appropriate for human consumption is donated to the Northern Illinois Food Bank for distribution to northern Illinoisans in need of food assistance. In 2011-2012, results were obtained from 8,175 deer tested statewide for CWD. Fortunately, only 36 deer in seven counties were found to be CWD-positive. The highest number of positives was found in Kane County (seven), followed by Boone (five), DeKalb (five), Grundy (five),

McHenry (three), Ogle (two) and Stephenson (two). Most tested samples were from hunter-harvested deer (6,726 samples — 82 percent of the total), but sharpshooting accounted for most of the sick deer identified (25 positives, 69 percent of the total). Most positive deer were found in areas already known to have CWD, although expansion into eastern Grundy County was noted. While most other states and provinces affected by CWD have experienced outbreaks that continue to worsen, infection rates in Illinois have remained relatively stable at low levels, averaging just below 1 percent for the 10 counties where CWD is known to occur.

CWD is distributed in a very patchy pattern in northern Illinois, and there are “hot spots” with much higher infection rates than other areas. Highest infection rates during 2011-2012 were found along the Boone-Winnebago county line from Wisconsin south to northwestern DeKalb County. Of interest is a pattern of decreasing infection rates observed in each of the last three years in the northern part of that area (north and northeast of Rockford), where infection rates declined to 5.4 percent this year. This is the area where the disease was first observed, and which historically has had the highest infection rates.

However, in the southern portions of this band, infection rates have remained steady or have been increasing, reaching Illinois’ highest rate of 12.4 percent in NW DeKalb and NE Ogle counties this past year. This pattern may be the result of differences in our ability to implement the CWD Management Program — landowner cooperation and support is very high in the northern area, but cooperators are much fewer in the south. Concerned, cooperating landowners are the key to disease management, and in the absence of that, disease control efforts cannot be successful.

Illinois’ program of CWD surveillance and active management during the past 10 years has successfully suppressed the rate of disease at very low levels. There is much work left to be done, however, and state budgets are very tight. There is strong evidence from around North America that when left unmanaged, CWD will increase and expand, with potentially devastating consequences for deer populations in the long term.

White-tailed deer are one of our most revered natural resources, and I’d like to think that Illinoisans will do everything in their power to protect that resource. I believe the future of white-tailed deer in all of Illinois lies in the hands of landowners and sportsmen in our CWD-positive areas.

2011-2012 annual report Illinois CWD management and surveillance summary

What is being done in Illinois to monitor wild and captive deer and elk herds for CWD? The Illinois Department of Natural Resources is testing thousands of animals from Illinois’s wild deer population. The Illinois Department of Agriculture monitors captive deer and elk herds in the state. Also, the Department of Agriculture obtains samples from captive deer and elk herds at slaughter plants.


Cervids can only enter Illinois if they originate from a herd that has been under a Chronic Wasting Disease (CWD) monitoring program for at least five years; additions to the herd are natural additions or have been in the herd at least one year; the herd has been under veterinary supervision for at least five years; and complete herd records, including purchases, deaths and causes of death of any member(s) of the herd are maintained for at least five years. The animal(s) must be accompanied by a certificate of veterinary inspection stating that the animals are free of visible evidence of any contagious, infectious or communicable disease and do not originate from a CWD endemic area. An endemic area is defined as any county and surrounding counties where CWD has been diagnosed in the past five years. An entry permit is also required.

A. All cervidae (deer and elk) twelve (12) months of age and over originating from Accredited Tuberculosis Free Areas, shall be negative to two single cervical tests for bovine tuberculosis no less than 90 days apart with the second test conducted within 90 days prior to the movement and were isolated from all other members of the herd during the testing period unless they originate from an accredited, qualified or monitored

Cervids from an accredited herd may be moved into Illinois without further tuberculosis testing provided that they are accompanied by a certificate stating that such cervids originated from an accredited herd. Cervids originating from qualified or monitored herds may enter Illinois with a negative test within 90 days prior to importation and a certificate stating that the animals originate from a monitored herd. Cervidae originating from Non Accredited Bovine Tuberculosis Free Areas, must originate from a herd where a complete herd test has been conducted within the past year and all animals found negative to a single cervical test using 0. 1 PPD Bovis tuberculin in the midcervical region with reading by observation and palpation at 72 hours, plus or minus 6 hours, and the individual animals entering Illinois were negative to two single cervical tests conducted within 180 and 30 days prior to entry. Institutions that have been accredited by the American Zoo and Aquarium Association (AZAA) are exempt from these requirements when movement is between accredited member facilities. All other movement from AZAA accredited members must comply with these movement requirements. B. All cervidae must be individually identified by ear tag, microchip or tattoo.

C. An entry permit, in addition to a Certificate of Veterinary Inspection, is required for the entry of all cervidae for any purposes. Permit may be obtained by calling (217)782 4944, Monday – Friday between 8:00 AM and 4:30 PM.

D. Applicant for entry permit shall furnish the following information to the Illinois Department of Agriculture, Bureau of Animal Health and Welfare: Number and unique identification of cervidae in shipment; name and address of consignor; name and complete post office assigned mailing address of Illinois consignee; anniversary date and herd certification number of the source herd; and name and telephone number of the herd veterinarian.

E. All cervidae must also be in compliance with the Illinois Wildlife Code.

F. In addition to the above, all elk six months of age and over, shall originate from a certified brucellosis-free herd or be negative to a brucellosis card or PCFIA test conducted within 60 days prior to entry.

All elk entering Illinois 6 months and older must originate from a brucellosis-free herd or be negative to a brucellosis card test or PCFIA test within 60 days of import, certification of brucellosis free herds shall be established and maintained in accordance with the Brucellosis Uniform Methods and Rules approved by USAHA; All cervids must be in compliance with Illinois Diseased Animals Act, 8 Ill. Adm. Code 85 and Ill Bovidae and Cervidae Tuberculosis Eradication Act; Must be accompanied by a permit from IDA and a CVI; See specific regulations relating to CWD at right, Individual ID number.

CVI must state that cervid does not originate from a CWD endemic area (any county or surrounding area where CWD has been diagnosed in the past 5 years); must originate from a herd that has been CWD monitored for at least 5 years under a state approved CWD certification program and was CWD free for that period and must meet the following criteria: any additions to herd must be natural or in herd for at least one year, complete records must be maintained for 5 years, animals have not been exposed to any animal from a herd diagnosed with CWD in the past 5 years, herd has been under vet supervision for a minimum of 5 years and has no exposure to any cervid from a CWD trace-back or trace-forward herd, statement must be signed by herd owner stating that all information on CVI is correct.


Any cervid dying from an unknown cause that has exhibited neurological disorder must be tested for CWD; any cervid exhibiting symptoms of CWD will be destroyed and tested or quarantined until it can be determined that the animal does not have CWD. Two 'voluntary' CWD herd monitoring programs have been established ("Certified Monitored vs. "Contained Monitored") - intrastate movement or sales of cervids will be contingent upon participation in one of the programs. To date, no captive cervids have tested positive for CWD.

More than 65,000 wild deer have been tested since 1998, with the first positive found in October 2002. To date (May 3, 2012) 372 positive deer have been identified from 10 counties (Jo Daviess, Stephenson, Boone, Winnebago, McHenry, Ogle, DeKalb, Kane, LaSalle, and Grundy) in northern Illinois. Sample are taken from suspect animals and from deer taken by hunters and sharpshooters

Two ‘elk’ slain near Antoich were European red deer that escaped from farm

BY DALE BOWMAN For Sun-Times Media November 8, 2012 10:28PM

Updated: November 9, 2012 2:31AM

It’s mistaken identity gone wild. Ron Mulholland thought he arrowed two wild elk last Friday from his deer stand on a farm outside of Antioch.

When James Minogue saw the story in Wednesday’s Sun-Times, he recognized the pair of breeding European red deer from the herd he helps manage for Avery Brabender on a farm in unincorporated Antioch. They, along with four others, escaped some time after Oct. 31 when a gate was opened or left open.

“It amazed me that they think they are elk and wild,’’ Minogue said.

However, elk and red deer are close enough to interbreed.

“I will talk to him,’’ Mulholland said. “I assumed they were wild and killed them. To me, they were elk. I don’t know. ... I feel bad for the guy that he would lose them. I reacted because I assumed it was an elk and I shot him.’’

“You don’t see elk in the wild in Illinois,’’ said Kevin Bettis, the duty officer in Springfield Thursday for the Illinois Conservation Police.

That’s tricky. A decade ago, Illinois didn’t have wolves or cougars, either. Both species now make regular appearances.

“These animals were hand-fed: We feed them bread, apples, corn,,’’ Minogue said.

Another tricky part is neither elk nor European red deer are protected or regulated under Illinois’ wildlife code. But these European red deer are considered domesticated animals. The herd is registered with the Illinois Department of Agriculture.

“It is no different than shooting a cow,’’ Bettis said.

However, Capt. Neal Serdar of Region II (northeast Illinois) checked with CPOs in southern Illinois, where escaped animals of such sort are more a more frequent issue.

Then he said, “The individual who shot the two red deer did not break any laws.’’

The Illinois Conservation Police consider the case closed. Whether there is any civil case would seem tricky at best, since the animals were loose.

Minogue said they recaptured two of the red deer already. He said the reason there were no ear tags is because they are a “contained, monitored herd.’’

It sounds like both parties can work it out.

“If it gets down to that, I would give him the antlers,’’ Mulholland said. “But I kind of feel it is his responsibility.’’

16 more CWD deer discovered


Tests for chronic wasting disease found 16 more confirmed cases in northern Illinois this fall [2006], bringing the total to 163 since the state's 1st infected deer was discovered in 2002 near Roscoe. The positive tests came from deer killed by firearm and archery hunters and a few suspicious deer taken by DNR staff. Winnebago and DeKalb counties each had 6, Boone County 4. All but one case was from deer in previously infected areas. The exception was a deer killed in southern DeKalb County, about 7 miles from the LaSalle County line. The state has included southern DeKalb in next month's [January 2007] special CWD hunt because of the new discovery. The latest positives came from about 2500 deer. Tests have not been completed on all deer sampled during the firearm seasons. Midwest states had increased firearm deer harvests this season. Illinois' total was 115 192 deer, compared with 114 209 last year [2005]. Wisconsin's harvest was 336 211, compared with 325 630 in 2005. Michigan's harvest was up about 7 percent at about 258 000. Minnesota doesn't yet have a total, but officials expect it to surpass 250 000, which would place it among the state's 5 best harvests.

Singeltary Sr. flounder9@verizon.net

[It is interesting that 2 of the 3 states named as having a larger deer harvest have CWD and that the 3rd state's deer have been involved in the tuberculosis outbreak in Michigan. There are no links to indicate that CWD has caused any human health problems. - Mod.TG]

Illinois CWD, see where there 2003 sampling showed 2. % of fawns tested had CWD i.e. 1 positive out of 51 samples.
