Individual working on a U.S. dairy farm reported to have avian influenza

The Center for Disease Control and Prevention in the U.S. has now confirmed a human case of avian influenza with an individual that had contact with dairy cows that were believed to have the virus.

The individual's only symptom seemed to be eye inflammation.

The H5N1 bird flu human health risk for the U.S. is still considered to be low, however they note the risk is higher for anyone exposed to infected birds or animals.

Last week, the USDA confirmed that highly pathogenic avian influenza had been detected in some dairy herds across several states ...  including Texas, Kansas, Michigan, and most recently in New Mexico and Idaho.

The USDA confirms wild migratory birds are believed to be the source of the infection.

Producers with the affected cows have reported a rapid onset illness in the herd, specifically among older, lactating cows.

Dairy farmers and veterinarians report that most affected cows recover in about two to three weeks.

Even though its only been found in dairy cattle it resulted in some market uncertainty in the US beef market earlier this week, while the hog markets seemed to gain some ground.

Video: Methionine Requirements for Lactating Sows - Cierra Kozole


In this episode of The Swine Nutrition Blackbelt Podcast, Cierra Kozole, PhD candidate in Swine Nutrition at the University of Guelph, explains how methionine supports lactating sows beyond milk protein synthesis. She discusses updated requirement estimates, source comparisons, methylation demand, and why modern sow genetics may require more precise amino acid strategies. Listen now on all major platforms!

"Methionine supports protein synthesis while also serving critical functions through methylation pathways that influence multiple biological processes."

Meet the guest: Cierra Kozole / cierra-kozole-772b64253 is a PhD candidate in Swine Nutrition at the University of Guelph in Canada. Her doctoral research focuses on refining estimates of methionine requirements for primiparous lactating sows, including evaluating methionine sources, nutrient partitioning, methylation reactions, and the links among amino acid supply, milk production, and sow protein retention.
