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

Arizona-based produce company SunFed Produce announced a recall of their cucumbers over links to a salmonella outbreak.

At least 68 people have fallen ill in the outbreak believed to be linked to cucumbers sold in the United States and Canada, the Centers for Disease Control and Prevention said.
