LAGRANGE COUNTY, Ind. -- The Indiana State Board of Animal Health (BOAH) reported Tuesday that it found two commercial egg or duck meat facilities testing positive for the H5N1 influenza virus, the highly pathogenic avian influenza.

Two flocks have been identified as infected and have since been quarantined. The larger of the two is based in LaGrange County, consisting of 19,285 birds used as commercial egg layers.

The first flock's 10 km control area consists of portions of Elkhart, LaGrange, and Noble Counties. The 20 km surveillance zone includes parts of those counties as well as parts of Kosciusko County.

The second flock is based on Elkhart County, consisting of 14,538 birds used for commercial duck meat. That flock's 10 km control area consists of portions of Elkhart and LaGrange Counties. The 20 km surveillance zone includes parts of those counties as well as parts of Noble County.

BOAH will be reaching out to flock owners within the surveillance zones to offer testing of their flocks. Wild birds in and near the control areas are also being surveilled.

Indiana Grade A dairy farms within control areas will also be tested for the influenza.

According to the BOAH, avian influenza does not present a food safety risk. Cooked poultry and eggs, as well as pasteurized dairy products, are safe to eat.

The BOAH also recommends hobby poultry owners report illness or deaths to the USDA Healthy Birds Hotline at (866) 536-7593.
