Avian Influenza Identified in McPherson and Rice Counties


By the Kansas Department of Agriculture


MANHATTAN, Kan. — The Kansas Department of Agriculture, in conjunction with the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA–APHIS), has identified highly pathogenic avian influenza (HPAI) in two egg layer facilities — one in McPherson County and one in Rice County. This marks five cases of HPAI in Kansas this fall; since the start of the outbreak in 2022 there have been 21 cases of HPAI in Kansas.

KDA is working closely with USDA–APHIS on a joint incident response at the affected premises in the two affected counties. According to KDA’s animal health officials, the facilities both increased their biosecurity upon the initial HPAI outbreak in 2022 and have been continuously monitoring their flock. Upon noticing clinical signs of HPAI in their birds, they immediately contacted KDA. The affected premises were placed under quarantine and the birds will be humanely depopulated and disposed of in an approved manner to prevent the spread of the disease.

In addition, KDA will be establishing a 20-km surveillance zone around the infected premises, and other farms or properties with poultry that fall within that zone will not be allowed to move birds or poultry products on or off their property without permission from KDA. The animal health team is working to locate all poultry owners in the area to ensure they know the symptoms of HPAI and are taking critical steps to protect their birds. If you own poultry and live in McPherson or Rice counties, please contact KDA at 833-765-2006 or [email protected]. You can also self-report your birds at

This outbreak of HPAI is primarily spread by migrating wild waterfowl, so a critical part of protecting your flock is to establish separation between your domestic birds and wild birds as they migrate through your region. Anyone involved with poultry production from the small backyard chicken owner to the large commercial producer should review their biosecurity activities to assure the health of their birds. Find guidance on biosecurity on the KDA Division of Animal Health webpage at

Highly pathogenic avian influenza is a contagious viral disease that can infect chickens, turkeys and other birds and can cause severe illness and/or sudden death in infected birds. Poultry owners should attentively monitor your birds for symptoms of HPAI which include: coughing, sneezing, nasal discharge, and other signs of respiratory distress; lack of energy and appetite; decreased water consumption; decreased egg production and/or soft-shelled, misshapen eggs; incoordination; and diarrhea. Avian influenza can also cause sudden death in birds even if they aren’t showing other symptoms.

If these symptoms are observed in your birds, immediately contact your veterinarian. If you don’t have a regular veterinarian, contact KDA’s Division of Animal Health office toll-free at 833-765-2006. 

According to the U.S. Centers for Disease Control and Prevention, the recent HPAI detections do not present an immediate public health concern or a food safety concern.  As a reminder, the proper handling and cooking of all poultry and eggs to an internal temperature of 165˚F is recommended as a general food safety precaution.
