Southern Indiana Business Report
DUBOIS COUNTY — Just two weeks after highly pathogenic avian influenza was confirmed on a Dubois County turkey farm, nearly 155,000 birds at five sites in two Southern Indiana counties have been destroyed in containment efforts by the Indiana State Board of Animal Health (BOAH).
The agency reported Feb. 23 that lab testing of a commercial turkey flock in Dubois County has identified H5 avian influenza virus. The case is considered presumptive positive pending verification by the USDA National Veterinary Service Laboratory in Ames, Iowa. Depopulation efforts are underway at the site, which houses 35,908 birds. This is the third farm in Dubois County to be diagnosed with avian influenza.
Timeline of events
The farm is approximately 2.5 miles from the Dubois County farm where a case of H5N1 highly pathogenic avian influenza (HPAI) was identified in a single commercial turkey flock back on Feb. 9. The incident marked the first report of HPAI in commercial poultry in the United States since 2020 and the first in Indiana since 2016.
Samples were collected from the birds on Feb. 7 and submitted to the Indiana Animal Disease Diagnostic Laboratory at Purdue University after approximately 100 birds died, the flock appeared lethargic, and consumption of water decreased. Tests indicated a likely infection of an H5 avian influenza virus.
Under standard protocols, the results were reported to BOAH, which authorized prompt transport of the samples to the National
Veterinary Services Laboratory in Iowa for confirmatory testing. NVSL confirmed that the virus present was a highly pathogenic strain of H5N1 (with a Eurasian H5 goose/Guangdong lineage). Upon confirmation of HPAI, the 29,000 turkeys in the flock (known as Dubois 1) were depopulated to prevent the spread of the disease in the area.
On Feb. 15, laboratory testing of a second commercial flock of turkeys in Dubois County identified the H5 avian influenza virus. Upon confirmation of HPAI, the 26,473 turkeys in the flock, known as Dubois 2, were depopulated to prevent the spread of the disease in the area.
On Feb. 18, laboratory testing identified H5 avian influenza in a commercial turkey flock in Greene County. A total of 15,400 turkeys in the flock known as Greene 2 were depopulated.
Ongoing measures
A 10-kilometer control area has been established around each HPAI-affected flock. All commercial flocks in the control areas must be tested for avian influenza at least weekly. Small hobby flocks are also subject to
testing. A surveillance zone is also established in the 10-km circle beyond the control area. Flocks in the surveillance zone must be tested every other week.
BOAH is working with multiple state and federal partners to respond to this event, including Indiana Department of Health; Indiana Department of Homeland Security; Indiana Department of Natural Resources; Indiana Department of Environmental Management; and USDA Veterinary Services, Wildlife Services, and Farm Service Agency.
Food safety
Avian influenza does not present a food safety risk; poultry and eggs are safe to eat. Officials are not aware of any public health significance with this virus. No cases of human infection have been reported. Human health agencies will be monitoring workers and others in contact with birds to monitor for influenza-like illness.
Animal health
Hobby poultry owners are encouraged to be aware of the signs of avian influenza and report illness and/or death to the USDA Healthy Birds Hotline at 866-536-7593. Callers will be routed to a state or federal veterinarian in Indiana for a case assessment. Dead birds should be double-bagged and refrigerated for possible testing.
Signs include sudden death without clinical signs; lack of energy or appetite; decreased egg production; soft-shelled or misshapen eggs; swelling or purple discoloration of head, eyelids, comb, hocks; nasal discharge; coughing; sneezing; lack of coordination; and diarrhea.
