Walmart, Wegmans and Albertsons stores have recalled cucumbers for possible contamination with salmonella. They were sold in more than half of states.

Cucumbers shipped to the U.S. and Canada — and organic eggs sold in 25 Costco stores in five southern U.S. states — have been recalled because of potential salmonella contamination

At least 68 people, including 18 that needed to be treated at hospitals, have fallen ill across 19 states in a salmonella outbreak that may be linked to cucumbers, the Centers for Disease Control and Prevention said on Friday.
