A salmonella outbreak linked to cucumbers has left at least 68 people sick, according to federal regulators. The Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) are investigating a nationwide outbreak of salmonella linked to recalled cucumbers.

A recall of cucumbers related to a salmonella outbreak that has left 68 people sickened has expanded to include produce sold by two additional companies in 25 states. The expanded recall comes just days after the U.

Over the weekend, the threat of salmonella triggered the recall of 10,000 cartons of organic eggs sold at Costco and whole cucumbers sold in 28 states.
