Food and Drug Administration officials says they have found positive samples of salmonella at the two Iowa farms involved in a massive egg recall.
The officials said investigators found salmonella in chicken feed that was sold to both Wright County Egg and Hillandale Farms.
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.
