Washington State University Researchers to Track Virus Transmissions Between Livestock and Humans

By Alejandro Figueroa

The project, which is being funded by a $1.5 million grant from the Centers for Disease Control and Prevention and the Washington Department of Health, will build up capacity for the WADDL to track diseases like the H5N1 avian flu strain that’s spread to dairy cattle, and like SARS-CoV-2, or COVID-19.

So far, over 80 dairy cattle herds in 10 states, including Idaho, New Mexico, Colorado, Kansas, Michigan, North Carolina, Ohio, South Dakota and Texas, have had positive cases of the avian bird flu strain, according to the CDC. It’s the same strain that has already devastated the U.S. poultry industry, including in Oregon and Washington, and caused billions of dollars in losses. Neither Oregon or Washington have positive cases of infected dairy cattle with bird flu.

Dr. Kevin Snekvik, a veterinary medicine professor at Washington State University in Pullman and the executive director of WADDL, said his team will track and compare respiratory viruses like bird flu and see if there are any genetic similarities between samples from livestock animals and humans.

“If you do that enough times across enough animals and farms, you can start to develop a picture of where that virus came from and track how it’s moving through the population,” he said.

In a statement, Dr. Thomas Waltzek, a virologist at WADDL, said if the team can better detect a virus and where it came from, it can help agriculture and public health officials minimize that disease’s spread across the Pacific Northwest.

“These are species that have the potential to spread diseases to humans,” Waltzek said. “It’s all about detecting these diseases quickly, determining if the viruses have pandemic potential and immediately taking corrective actions to hopefully prevent a pandemic.”

Snekvik said one component of the project is focused on public health, but it’s also about safeguarding regional and national food security.

In this episode of The Swine Nutrition Blackbelt Podcast, Kynna Crawford, Graduate Research Assistant at South Dakota State University, discusses how Plackett-Burman designs can help screen nursery diet ingredients for early post-weaning feed intake. She explains why low intake after weaning contributes to stress and mortality, how screening trials can evaluate multiple ingredients in a single study, and how the approach can support both research and commercial nursery nutrition decisions.

"A single screening trial can help identify which nursery ingredients deserve deeper research for early post-weaning feed intake."

Meet the guest: Kynna Crawford / kynna-crawford-a2610a3aa is a Master's student in Animal Sciences at South Dakota State University, where her work focuses on swine nutrition and nursery pig management. Her research examines strategies to alleviate weaning stress, including dietary approaches and screening tools to identify ingredients that may promote early feed intake.
