Highly pathogenic avian flu outbreaks, which ramped up again in early October, continue to take a heavy toll on commercial poultry farms, with the virus hitting a massive layer farm in Ohio that houses more than 1.3 million birds and more turkey producers in Minnesota, South Dakota, and Wisconsin, the US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) said in its latest updates.
Also, the virus struck a broiler farm in Maryland and a duck-breeding facility in Georgia, marking the state's first outbreak at a commercial farm. Also, Florida and Texas reported detections in backyard flocks.
The H5N1 outbreaks, which began in February 2022, have led to a record loss of nearly 66 million poultry across 47 states.

In developments abroad, the Finnish Food Agency reported 5 more H5N1 outbreaks on fur farms, raising the total to 65. Animal health officials are testing animals at all of the country's fur farms and recently reported 24 more over the past few weeks. Four of the latest affected farms raised blue fox, and one produced raccoon dogs.
Elsewhere, Japan reported its first poultry farm outbreak of the season, which occurred at a farm in Saga prefecture that houses 40,000 chickens, according to The Mainichi, a daily newspaper in Japan. The report did not list the subtype.
