HPAI Alert: Highly Pathogenic Avian Influenza Detected in New Michigan Dairy Herd

MDARD Director Tim Boring has confirmed highly pathogenic avian influenza (HPAI) cases in dairy herds across Allegan, Clinton, Gratiot, Ingham, and Isabella counties. The Michigan State University Veterinary Diagnostic Laboratory confirmed these cases, with samples sent to USDA’s National Veterinary Services Laboratory for further testing.

Biosecurity measures are crucial to combat HPAI. Director Boring’s “Emergency HPAI Risk Reduction and Response” Order, issued on May 1, 2024, mandates enhanced biosecurity measures for all Michigan dairy operations. Additional guidance issued on May 3, 2024, supplements these requirements, effective since May 8, 2024.

Key steps to safeguard Michigan’s dairy cattle include isolating new animals, daily health monitoring, and limiting farm visitors. MDARD collaborates with veterinarians to monitor animal health and conduct trace investigations.
