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: Screening Nursery Ingredients - Kynna Crawford


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.
