WASHINGTON, May 20, 2015 - The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H5N2 avian influenza (HPAI) in four additional flocks in Minnesota and Iowa. No human infections with the virus have been detected at this time. CDC considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low.
USDA’s National Veterinary Services Laboratories confirmed HPAI H5N2 in the following counties and states:


Renville County, Minnesota (May 19, 2015)
625,500 chickens
2nd detection in this county

Kandiyohi County, Minnesota (May 19, 2015)
42,600 turkeys
33rd detection in this county


Sac County, Iowa (May 19, 2015)
28,400 turkeys
5th detection in this county


Sioux County, Iowa (May 19, 2015)
Backyard flock (number pending)
5th detection in this county


The affected premises have been quarantined and birds on the property will be depopulated to prevent the spread of the disease. Birds from the flock will not enter the food system.


According to USDA’s National Agricultural Statistics Service, in 2014, the U.S. poultry industry produced 8.54 billion broiler chickens, 99.8 billion eggs, and 238 million turkeys.


The United States has the strongest AI surveillance program in the world. As part of the existing USDA avian influenza response plans, Federal and State partners as well as industry are responding quickly and decisively to these outbreaks by following these five basic steps: 1) Quarantine – restricting movement of poultry and poultry-moving equipment into and out of the control area; 2) Eradicate – humanely euthanizing the affected flock(s); 3) Monitor region – testing wild and domestic birds in a broad area around the quarantine area; 4) Disinfect – kills the virus in the affected flock locations; and 5) Test – confirming that the poultry farm is AI virus-free. USDA also is working with its partners to actively look and test for the disease in commercial poultry operations, live bird markets and in migratory wild bird populations.


For more information about the ongoing avian influenza disease incidents visit the APHIS website. More information about avian influenza can be found on the USDA avian influenza page. More information about avian influenza and public health is available on the CDC website.

Epidemiological comments The USDA Animal and Plant Health Inspection Service (APHIS), in conjunction with State Departments of Agriculture and Wildlife, are continuing to conduct a comprehensive epidemiological investigation and enhanced surveillance (including wild bird surveillance of hunter harvested birds) in response to the HPAI H5N8 and H5N2 wild bird related events. Novel avian influenza virus of Eurasian origin (EA-H5N8 clade 2.3.4.4) spread rapidly along wild bird migratory pathways during 2014. Introduction of this EA-H5N8 virus into the Pacific Flyway sometime during 2014 has allowed mixing with North American (AM) lineage viruses and generated new combinations with genes from both EA and AM origin (or “reassortant” viruses) such as this EA/AM H5N2-reassortant detected in the US. In addition, overlap of the Pacific, Central, and Mississippi Americas flyways has resulted in movement of the virus to the central part of the country. The EA-H5 clade 2.3.4.4 viruses are highly pathogenic for poultry.
