A mixed-species backyard flock of 86 birds in Benton County was recently infected by a highly transmissible avian flu, according to the Iowa Department of Agriculture and Land Stewardship.
It is the 14th detection of the virus in Iowa this fall. The infections have led to the culling of about 1.4 million birds to prevent the virus’ spread.
Highly pathogenic avian influenza is transmitted by migrating birds and is often lethal for domestic flocks. Infections in Iowa last year in October, November and December affected about 2.5 million birds.
This year, virus detections have been more frequent but have affected smaller flocks. The other detections were:
— Nov. 13: A game bird hatchery in Kossuth County with about 13,000 pheasants, quail and chukars.
