Walmart, Wegmans and Albertsons stores have recalled cucumbers for possible contamination with salmonella. They were sold in 26 states, the FDA says.

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.

The FDA this week announced that 68 Americans have been infected with the strain of salmonella found in cucumbers sold by SunFed Produce.
