Food and Drug Administration officials say they have found positive samples of salmonella that link two Iowa farms to a massive egg recall.
The officials said investigators found salmonella in chicken feed that was sold to both Wright County Egg and Hillandale Farms. They also found salmonella samples at Wright County Egg. More than 550 million eggs from the two farms were recalled this month after they were linked to as many as 1,300 cases of salmonella poisoning.
Sherri McGarry of the FDA's Center for Food Safety and Applied Nutrition said the tests indicate that contaminated feed is a source of the outbreak but possibly not the only source.
Also Thursday, the federal Centers for Disease Control said that there could now be as many as 1,470 illnesses linked to the outbreak.
The House Energy and Commerce Committee will hold hearings on the recall in September.
