U.S. Bird Flu Outbreak Hits Millions of Iowa Egg-Laying Hens

Updated on

Many of the 3.8 million egg-laying hens in an Iowa flock probably have bird flu as the biggest single outbreak of the virus reported in the U.S. added to concerns that turkey and egg supplies will be hampered by the disease.

“Despite best efforts, we now confirm many of our birds are testing positive” for avian influenza, closely held Sonstegard Foods Co. said in a statement dated April 20. The company said its Sunrise Farms unit close to Harris, Iowa, in Osceola County has 3.8 million hens.
