NMPF’s Jonker, Hain See Bird Flu Lessons One Year Later

Dairy farmers have boosted biosecurity and researchers have learned much about the H5N1 bird flu virus in dairy cattle one year after its introduction, top NMPF experts said in a Dairy Defined podcast. Still, the hope is that the virus may leave the dairy herd completely. 

“We’re still learning things about the virus and how it’s being transmitted from farm to farm, and we still need some answers on that, but hang in there, we’re going to get through this,” said Dr. Jamie Jonker, NMPF’s chief science officer. “I do believe we’re going to eliminate the virus from the U.S. dairy cattle population. I think it’s just a matter of when, not if.” 

Since the H5N1 Avian Influenza virus was first reported in cattle in March 2024, more than 1,000 dairy herds have been infected, Jonker said. Still, successful eradication has taken place in some areas, and the lack of evolution of the viruses within cattle has created hope. Dr. Meggan Hain, NMPF’s chief veterinary officer, said biosecurity practices are key to containment and elimination. The National Dairy FARM (Farmers Assuring Responsible Management) Program offers a wealth of materials that can assist, she said.  

Bird flu has “given us a chance to really learn some of the lessons of, where do we have opportunities, where are there things that we’ll want to sort of dig into so that we’re better prepared in the future if we do get challenges,” she said. “I think there’s a lot of things we can take away from this that we can really make improvements on.”

Dairy Groups Applaud Administration Vaccine Support, Thank USDA for Plan

Leaders from the National Milk Producers Federation (NMPF) and the International Dairy Foods Association (IDFA) released the following statements today in response to the Trump Administration’s updated response plan for highly pathogenic avian influenza (HPAI) that is affecting our nation’s dairy herds.

NMPF President and CEO Gregg Doud said the following: “Dairy farmers and cooperatives appreciate USDA’s leadership in supporting American agriculture and safeguarding animal health as it deals with what soon will be a second year of H5N1 bird flu disruptions in dairy cattle. Dairy farmers and all of agriculture takes biosecurity seriously, and we thank USDA and the Trump Administration for actions that will further those efforts.

“We support the department’s initiatives to advance vaccine development and deployment that will help control, and ultimately eliminate, the virus in dairy cattle. And we also want to remind consumers that, even as dairy farmers are working with veterinarians and officials at all levels of government to eliminate this animal health threat, milk for consumers remains safe to drink because of the effectiveness of pasteurization.”

IDFA President and CEO Michael Dykes, D.V.M., said the following: “The International Dairy Foods Association is grateful to Agriculture Secretary Rollins for investing up to $100 million in new and ongoing research into animal vaccinations and therapeutic tools to manage highly pathogenic avian influenza in our nation’s dairy herds and commercial poultry flocks. We continue to urge USDA and its federal partners to act quickly to develop and approve the use of safe, effective bovine vaccines to guard against current and future strains of avian influenza affecting U.S. dairy. It is essential that the federal government work with our industry to ensure a vaccination strategy is feasible and cost-effective for farmers while working with international trading partners to assure the use of vaccines does not limit or disrupt U.S. agricultural exports.”
