H5N1 Avian Flu Strikes More Poultry in 4 States

Jan 29, 2025

By Lisa Schnirring

The US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) today confirmed more H5N1 avian flu detections in poultry from four states, including several in hard-hit Ohio.

The latest outbreaks in Ohio involved four commercial farms in Mercer County, three turkey producers and one at a duck meat facility. Over the past month, Ohio’s outbreaks have led to the loss of nearly 6 million birds, including several large layer farms, with most of the other events involving turkey producers.

APHIS also confirmed an outbreak at a layer farm in Arizona’s Pinal County that has about 316,000 birds. Officials also confirmed two detections in backyard flocks, one in Nebraska’s Kearney County and one in Florida’s Orange County.

Since H5N1 was first detected in US poultry in early 2022, outbreaks have led to the loss of a record 147.25 million birds across all 50 states and Puerto Rico.

In dairy cow developments, APHIS confirmed one more detection, another herd from California, raising the national total to 944 and the state’s total to 727.

Video: Research in Action | Swine Cluster 4 - Activity 8: Precision Feeding with Dr. Aline Remus

Research in Action is a video series from Swine Innovation Porc that highlights the people and projects driving innovation in Canada's pork sector.

In this episode, Dr. Aline Remus (Agriculture and Agri-Food Canada) explains how precision feeding is helping producers improve efficiency, reduce feed costs and lower environmental impacts while supporting animal health and welfare.

As part of Swine Cluster 4 - Activity 8, this research is advancing precision livestock farming by tailoring nutrition to the needs of individual pigs or groups of pigs. The project aims to reduce feed costs, decrease greenhouse gas emissions and nutrient losses, and develop practical precision feeding systems that producers can confidently adopt on-farm.

By bringing together researchers from across Canada and around the world, this work is helping transform innovative research into practical solutions for a more sustainable and competitive Canadian pork sector.
