EDISON - The Food and Drug Administration says consumers should strictly avoid runny yolks as investigators continue their probe of a salmonella outbreak that has sickened about 1,300 people nationwide.

About a half-billion eggs have been recalled from two Iowa egg distributors.

Wright County Egg and Hillandale Farms initiated the recalls after officials at the Centers for Disease Control and Prevention (CDC) detected an uptick in salmonella cases.

Official expect the number of illnesses from the salmonella outbreak to increase.

Authorities say there is no indication that New Jersey stores offer the potentially contaminated eggs.
