(AP) -- The recall of eggs possibly contaminated with salmonella has swelled to 380 million. That's almost 32 million cartons.

Hundreds of people have been sickened in the outbreak, which currently extends to four states. But there have been no deaths.

The Centers for Disease Control and Prevention is working with state health departments to investigate the illnesses.

All the eggs, which were sold under numerous names, came from Wright County Egg of Galt, Iowa.
