The U.S. Food and Drug Administration (FDA) announced today that feed given to chickens at both Hillandale Farms and Wright County Egg could be the source of the Salmonella bacteria that has caused an outbreak of 2,403 confirmed illnesses throughout the United States.

As reported on today:

Testing at two Wright County Egg farms in Iowa confirmed the presence of Salmonella in the food mill and at least two locations, said Sherri McGarry of the Food and Drug Administration. She said investigators are still drawing samples at Hillandale Farms.

The feed could have been contaminated in a number of ways, including by birds, rodents and people’s shoes or boots, officials said.
