H5N1 Avian Flu Surges in Idaho's Dairy Cattle

May 05, 2025

The US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) today reported 15 more H5N1 avian flu detections in Idaho dairy cattle, which over the past several weeks have become the nation's epicenter of virus activity.

The pace of detections picked up in March, and the state has now reported 86 confirmations in dairy cows, the nation's second most behind California. The latest detections push the national total since March 2024 to 1,047 from 17 states.

The Idaho State Department of Agriculture said 59 herds in four counties are in quarantine. Most are in Gooding (34 herds) and Jerome (17) counties, but there are also a few in Twin Falls (7) and Cassia (1) counties. All are located near each other in the far south-central part of the state.

Idaho is the nation's third-largest milk producer and has more than 350 family-owned dairy farms, according to the agriculture department's dairy bureau.

Mammal detections, vaccine deal

In other H5N1 developments, APHIS reported 10 more H5H1 detections in mammals besides livestock from six different states. Most positive samples were collected in late March and into April. One case involved a domestic cat in Weld County, Colorado. The others were wildlife, including skunks from California and Colorado, a raccoon from New York, foxes from Virginia and Texas, and a weasel from Washington state.

Elsewhere, the European Commission this week announced a procurement commitment with CSL Seqirus that would allow 17 countries the opportunity to buy up to 27,403,200 million doses of pandemic flu vaccine as part of pandemic flu preparedness. The agreement would secure the vaccine if the World Health Organization or European Union declares a flu pandemic.

Video: Evolution of Beef Cattle Farming

The Clear Conversations podcast took to the road for a special episode recorded in Nashville during CattleCon, bringing listeners straight into the heart of the cattle industry. Host Tracy Sellers welcomed rancher Steve Wooten of Beatty Canyon Ranch in Colorado for a wide-ranging discussion that blended family history and sustainability, particularly as it relates to the future of beef production.

Sustainability emerged as a central theme of the conversation, a word that Wooten acknowledges can mean very different things depending on who you ask. For him, sustainability starts with the soil. Healthy soil produces healthy grass, which supports efficient cattle capable of producing year after year with minimal external inputs. It’s an approach that equally considers vegetation, animal efficiency, and long-term profitability.

That philosophy aligned naturally with Wooten’s involvement in the U.S. Roundtable for Sustainable Beef, where he served as a representative for the Colorado Cattlemen’s Association. The roundtable brings together the entire beef supply chain—from producers to retailers—along with universities, NGOs, and allied industries. Its goal is not regulation, Wooten emphasized, but collaboration, shared learning, and continuous improvement.
