The number of illnesses from tainted eggs is expected to rise.
Two Iowa egg farms have recalled more than half a billion eggs, eggs that have already sickened about 1,300 people.
More illnesses are expected.
The two farms share chicken and feed suppliers but investigators have yet to determine the source of salmonella contamination.
The farms are Wright County Egg and Hillandale Farms.
