USDA Confirms More H5N1 in Dairy Cows, Wild Birds, and Small Mammals

Aug 06, 2024

By Lisa Schnirring

The US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed three more H5N1 avian influenza outbreaks in dairy cattle, raising the national total to 181 from 13 states.

The latest confirmations are from Colorado, South Dakota, and Texas.

In other updates, APHIS also reported more detections in wild birds in mammals. The group reported about more than 100 more H5N1 detections in wild birds across several states. Some were waterfowl taken by hunters and were sampled last fall. However, several were agency-harvested birds from Colorado's Weld County, which has been a recent hot spot for dairy cow outbreaks, poultry outbreaks, and human illnesses. Species in Weld County that tested positive included doves, sparrows, starlings, and pigeons.

Regarding mammals, APHIS over the past few days has reported 27 more detections, raising its confirmed number to 373. Most of the newly confirmed positives involve deer mice and house mice from Weld County in Colorado. The group also included three domestic cats from Larimer County in Colorado, plus a rabbit and a vole from Weld County.

Video: Genetic Resistance to Post-Weaning Diarrhea - Dr. Vahab Farzan

In this episode of The Swine it Podcast Show, Dr. Vahab Farzan from the University of Guelph explains why post-weaning diarrhea remains a major challenge for swine production. He discusses genetics, gut microorganisms, immunity, diagnostics, and targeted vaccination strategies to improve disease prevention. Listen now on all major platforms!

“Some pigs are genetically resistant to pathogenic E. coli because they lack the specific receptors required for bacterial attachment.”
