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.

Whole fresh cucumbers from Sunfed Produce — sold at Walmart, Wegman's, and other retailers — have been linked to salmonella in the U.S. and Canada.
