MDARD Reminds Bird Owners to Continue Protecting Their Flocks from Highly Pathogenic Avian Influenza

Michigan Department of Agriculture and Rural Development (MDARD) has not reported any new cases of highly pathogenic avian influenza (HPAI) in domestic poultry flocks since December 2023, the virus continues to be detected throughout the United States and in Michigan's wild birds. These detections coupled with the spring migration of wild birds means it is still vitally important to protect domestic flocks and keep birds healthy.

The risk posed by HPAI is still present. As wild birds migrate this spring, their movement can cause the disease to spread once again, said State Veterinarian Dr. Nora Wineland, DVM, MS DACVPM. To best protect Michigan s domestic flocks, bird owners need to remain committed to taking every precaution they can to protect their birds from being exposed to wild birds and their germs. Keeping birds safe and healthy must continue to be a priority.

HPAI is a highly contagious virus that can be spread in various ways from flock to flock, including through wild birds, contact with infected poultry, by equipment, and on the clothing and shoes of caretakers.

MDARD reported Michigan s first case of HPAI in a domestic flock on February 24, 2022. Since this first detection, the department received over 280 calls about possible cases of the disease, which resulted in 93 investigations. These investigations led to the detection of 29 infected flocks: 23 involved backyard flocks, three cases occurred in hunting preserves, and three cases were in commercial flocks. These cases were found in 18 counties across the Upper and Lower Peninsulas.

In 2024, MDARD has already received calls regarding sick or dead domestic birds and initiated responses. So far this year, two potential cases of the disease have been investigated; both were negative for HPAI.

According to the U.S. Centers for Disease Control and Prevention, the public health risk associated with this disease remains low. In addition, no birds or bird products infected with HPAI will enter the commercial food chain. As a reminder, people should properly handle and cook all poultry and eggs.
