Another 22 people said they ate shelled eggs before contracting salmonella, the CDC reported.
Last month, more than 200 million eggs from the North Carolina farm were recalled because of bacterial contamination.
The egg recall is the largest in the United States since 2010, when 500 million eggs from an Iowa producer were recalled, and almost 2,000 illnesses caused by salmonella were reported.
A salmonella outbreak that led to the multi-state recall in April of more than 200 million eggs has worsened in recent weeks, with the number of people sickened by the bacteria rising to nearly three dozen.
In grocery stores, the eggs were sold under the following brands: Country Daybreak; Crystal Farms; Coburn Farms; Sunshine Farms; Glenview; Great Value (Walmart's store brand), and Food Lion's store brand.
The outbreak, traced to a single egg producer, has resulted in 11 hospitalizations.
Nine states have reported illnesses: Colorado, Florida, New Jersey, New York, Pennsylvania, Virginia, West Virginia, North Carolina and SC.
For a full list of recalled brands, consumers are urged to check the Food and Drug Administration's website.
With the newly released information in mind, the CDC advised consumers, restaurants, and retailers respectively not to eat, serve, or sell the eggs involved in the recall. At times, infections could be fatal, especially in young children or elderly people.
FDA officials inspected Hyde County farm, a facility in North Carolina that produces 2.3 million eggs a day, after initial reports of illnesses. It can cause diarrhea, fever and abdominal cramps in sickened individuals; for older adults, infants and people with weakened immune systems, salmonella can cause more serious, even life-threatening, complications. Alternatively, bacteria in the hen's ovary or oviduct can get to the egg before the shell forms around it. The bacteria can also pass through chicken feces getting on the eggs.
