Springfield, IL — Illinois health and agriculture officials announced Friday that the state has been declared “unaffected” by H5N1 avian influenza in dairy cattle, following coordinated surveillance and prevention efforts across farms, trade groups, and local agencies.
According to the Illinois Department of Public Health (IDPH) and the Illinois Department of Agriculture (IDOA), the U.S. Department of Agriculture (USDA) made the designation after testing and monitoring confirmed no presence of the virus in Illinois dairy herds. The USDA defines “unaffected” as evidence from ongoing surveillance that shows no disease in dairy cattle statewide.
Dr. Sameer Vohra, director of IDPH, said the recognition reflects strong collaboration between state and local partners. “Public health truly excels through the power of partnership,” Vohra said, noting the agencies’ continued coordination with dairy farms, agricultural organizations, and local health departments to maintain vigilance as migratory bird season continues.
Officials cautioned that while dairy cattle remain free of H5N1, wild birds migrating through Illinois could still carry the virus. The public is urged to avoid handling dead birds and to report multiple bird deaths to local health departments or wildlife biologists. IDPH also advises residents to seek medical care promptly if they experience flu-like symptoms after contact with sick or dead birds.
“The proactive work of Illinois farmers has kept our herds safe and our food supply secure,” said Illinois Department of Agriculture Director Jerry Costello II. He credited the state’s science-based approach and ongoing biosecurity efforts for the USDA’s favorable designation.
More information and guidance on H5N1 prevention can be found through IDPH and USDA online resources.
