IDOA & IDPH Vigilant Against H5N1 Influenza in Dairy Cattle

By Andi Anderson

The Illinois Department of Agriculture (IDOA) and the Illinois Department of Public Health (IDPH) are working diligently to monitor and prevent the spread of H5N1 influenza in dairy cattle, following its detection in herds across several states in the U.S.

Although no cases have been reported in Illinois, federal agencies have confirmed the presence of the H5N1 influenza virus in dairy herds in eight states. In response, IDOA and IDPH are collaborating closely to coordinate prevention and response measures to safeguard public health and the dairy industry.

As part of their efforts, IDOA and IDPH are working with producer groups and partner organizations to educate veterinarians and cattle farmers about the clinical signs of H5N1 influenza. Early detection of potential infections is crucial for swift containment and management.

Effective April 29th, the U.S. Department of Agriculture (USDA) has mandated testing for interstate movement of dairy cattle and required the reporting of positive results. These measures aim to limit the spread of the disease and prevent further outbreaks.

Dr. Mark Ernst, IDOA State Veterinarian, reassured the public by stating that affected dairy animals in other states have shown promising recovery rates with minimal mortality. He emphasized that the additional safety protocols are precautionary, and the risk of transmission to humans is low, as confirmed by the Centers for Disease Control and Prevention (CDC).

The U.S. Food and Drug Administration (FDA) affirms the safety of the commercial milk supply due to the pasteurization process, which effectively eliminates bacteria and viruses. Protocols are also in place to dispose of milk from affected dairy animals.

Dr. Sameer Vohra, IDPH Director, underscored the importance of prioritizing the safety of Illinois' milk supply and the well-being of individuals working with cattle and poultry. He advised against consuming unpasteurized raw milk products due to the potential risk of infection.

Illinois, home to over 600 dairy farms with approximately 73,000 cows or calves, remains vigilant in implementing preventive measures to protect the health and safety of its residents and the dairy industry.
