Egg recall for Salmonella: 2,000 sickened and 500 million eggs recalled

As the nation's massive recall of potentially contaminated eggs expands to more than half a billion eggs so does the number of those sickened -- rising to nearly 2,000 reported cases, according to the U.S. Centers for Disease Control and Prevention.

And it's becoming clearer that the already-staggering numbers are just going to get bigger. Dr. Margaret Hamburg, commission of the U.S. Food and Drug Administration, said on The Today Show that consumers will hear of yet more brands of eggs being recalled.

"We may see some additional sort of sub-recalls over the next couple of days, maybe even weeks, as we better understand the network of distribution of these eggs that are contaminated," she said.
