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.”
