First Iowa case of avian flu confirmed

April 14th, 2015

DES MOINES, Iowa — 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 a commercial turkey flock in Buena Vista County, Iowa. This is the first confirmation in a commercial flock in Iowa. The flock of 27,000 turkeys is located within the Mississippi flyway where this strain of avian influenza has previously been identified.

The Center for Disease Control (CDC) considers the risk to people from these HPAI H5 infections in wild birds, backyard flocks and commercial poultry, to be low. No human infections with the virus have been detected at this time.

Samples from the turkey flock, which experienced increased mortality, were tested at the Iowa State University Veterinary Diagnostic Laboratory and the APHIS National Veterinary Services Laboratories (NVSL) in Ames, Iowa confirmed the findings. NVSL is the only internationally recognized AI reference laboratory in the United States.

APHIS is working closely with the Iowa Department of Agriculture and Land Stewardship (IDALS) on a joint incident response. State officials quarantined the premises 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.

The United States has the strongest Avian Influenza (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 – confirm that poultry farms in the area are 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.

The Iowa Department of Agriculture and Land Stewardship is working directly with poultry workers at the affected facility to ensure that they are taking the proper precautions.

These virus strains can travel in wild birds without those birds appearing sick. People should avoid contact with sick/dead poultry or wildlife. If contact occurs, wash your hands with soap and water and change clothing before having any contact with healthy domestic poultry and birds.

All bird owners, whether commercial producers or backyard flock owners, should continue to practice good biosecurity, prevent contact between their birds and wild birds, and report sick birds or unusual bird deaths to state/federal officials, either through their state veterinarian at 515-281-5321 or through USDA’s toll-free number at 1-866-536-7593. Additional information on biosecurity for backyard flocks can be found at
