Duck tests positive for highly pathogenic avian influenza

A Northern shoveler harvested by a hunter in Hyde County tested positive for highly pathogenic avian influenza, or HPAI.

Biologists at the North Carolina Wildlife Resources Commission are reminding hunters to follow best practices when handling waterfowl after harvest.

The United States Department of Agriculture Animal and Plant Health Inspection Service announced the positive detection Wednesday, and that a second wild duck was confirmed to have H5N1 HPAI in Colleton County, South Carolina, Jan. 14. The North Carolina positive sample was collected Dec. 30, 2021.

This type of HPAI virus is considered low risk to people according to the U.S. Centers for Disease Control, but can be dangerous to other birds, including commercial and backyard flocks of poultry.

These are the first wild birds in the United States to have Eurasian H5 HPAI since 2016. The positive samples were collected by USDA as part of its surveillance program for early detection of HPAI in collaboration with state wildlife agencies. 

The positive detections in wild waterfowl are not unexpected, as they can be infected with HPAI and show no signs of illness. The birds can carry the disease to new areas through fecal material or oral discharges when migrating. 

Commission officials recommend that hunters take the following precautions offered by the USDA to protect themselves:

• Do not harvest or handle wild birds that are obviously sick or found dead.
• Wear rubber gloves when handling birds, cleaning game or cleaning bird feeders.
• Do not eat, drink or smoke while cleaning game.
• Dress your game birds in the field whenever possible. If you must dress your birds at home, clean them in an area separate from your poultry and pet birds.
• Double bag the inedible parts of the bird and feathers. Tie the inner bag and include your rubber gloves and leave them in the outer bag before tying it closed.
• Wash hands with soap and water immediately after handling game or cleaning bird feeders. If soap and water are not available, use alcohol wipes.
• Wash all tools and work surfaces with soap and water. Then, disinfect them.
• Avoid cross-contamination. Keep uncooked game in a separate container, away from cooked or ready-to-eat foods.
• Cook game meat thoroughly. Poultry should reach an internal temperature of 165 degrees Fahrenheit to kill disease organisms and parasites.

“If someone comes across a mortality event involving five or more waterbirds or waterfowl, or a mortality event of any size for raptors or avian scavengers, including crows, ravens and gulls, we want to know about them,” Joe Fuller, wildlife biologist with the commission said in a release. “We are also interested in morbidity events involving any number of those same bird species that are observed with clinical signs consistent with neurological impairment, like swimming in circles, head tilt and lack of coordination.”

The public is encouraged to direct wild bird reports to the NC Wildlife Helpline at 866-318-2401 8 a.m. to 5 p.m. Monday through Friday, email HWI@ncwildlife.org or call USDA at 866-536-7593.

Sick or dying captive birds should be reported to your local veterinarian, the NCDACS Veterinary Division, 919-707-3250, or the N.C. Veterinary Diagnostic Laboratory System, 919-733-3986. For more information on HPAI, visit the NCDACS website.
