HPAI Confirmed in Van Buren County Dairy Herd: Key Updates

We are committed to keeping you informed with honest, timely updates. The Michigan Department of Agriculture and Rural Development (MDARD) has detected highly pathogenic avian influenza (HPAI) in a Van Buren County dairy herd, increasing the total number of affected herds in Michigan to 27. The Michigan State University Veterinary Diagnostic Laboratory initially identified the case, with samples now sent to the USDA’s National Veterinary Services Laboratories for further testing.

To address the outbreak, MDARD’s Determination of Extraordinary Emergency HPAI Risk Reduction and Response Order (HRRRO) requires all Michigan dairy operations to enhance biosecurity measures. This includes a ban on exhibiting lactating dairy cattle and those in the last two months of pregnancy until no new HPAI cases are reported for at least 60 consecutive days.

Essential Biosecurity Measures:

• Delay or halt incoming animals from herds with uncertain health status.
• Isolate new or returning animals on your farm.
• Monitor animal health daily and consult your veterinarian as needed.
• Use dedicated equipment for sick animals and disinfect thoroughly.
• Avoid sharing tools and equipment between farms.
• Clean and disinfect trailers used for transporting animals.
• Limit non-essential visitors and ensure clean clothing and footwear for those entering your farm.

We’re here to support you with clear, empathetic communication. Let’s work together to keep our community safe. MDARD is working with veterinarians and federal partners to monitor the situation, conduct investigations, and provide personal protective equipment (PPE) upon request.
