36 | Big Game Info: 402-471-0641 Big Game Diseases CHRONIC WASTING DISEASE Chronic wasting disease is a fatal, transmissible prion disease of deer and elk. It is not known to spread to humans. Species specific prion diseases are present in sheep (Scrapie), cattle (BSE/ Mad Cow), mink (TME) and humans (Creutzfeldt-Jakob). CWD has been documented in wild deer populations of 32 states and has been detected in 58 Nebraska counties (See map below). Since 1997, the Nebraska Game and Parks Commission has tested more than 57,000 deer, with 1,269 positives. Since 2015, Game and Parks primarily has focused sampling on bucks 2 years or older, since they are the population segment most likely to have chronic wasting disease. The 2023 testing results were: How does CWD spread? — CWD is believed to be spread in deer herds by direct contact with infected animals or contaminated substances: saliva, urine, feces, blood, brain, spinal cord, or soil. There is no known method to eliminate chronic wasting disease from wild herds. How can we reduce the spread and reduce human contact with chronic wasting disease prions? — Follow these steps: • Educate yourself and others about it. • Do not artificially congregate deer by using supplemental feeds or methods that concentrate deer. These sites can become hot spots contaminated with feces, urine and prions from infected deer. Infected sites are impossible to clean up, but fencing or burial can reduce access. • Dispose of deer remains (bones and tissue) at a landfill. Place remains in a heavy plastic bag before disposal to prevent contamination of soil. DO NOT transport the carcass back to the field. How can I get my deer tested? — Hunters who wish to have a deer tested can contact an accredited lab in Nebraska or surrounding states for details by visiting aphis.usda.gov/animal_ health/nahln/downloads/cwd_lab_list.pdf.

MENINGEAL BRAIN WORM Meningeal brain worm is a disease that primarily affects mule deer and, to a lesser extent, elk with fatal results. It is a parasitic nematode that uses white-tailed deer as a host, but does not cause death. MBW has been a contributing factor in the decline and westward recession of mule deer in parts of Nebraska. Mule deer with MBW typically are observed standing out in the open and moderately unaware of their surroundings. EPIZOOTIC HEMORRHAGIC DISEASE SUMMARY In 2023, EHD detections and prevalence was lighter overall throughout the state. For more on EHD in Nebraska, visit OutdoorNebraska.gov.
