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.

Cucumbers distributed to more than two dozen US states and Canada are being recalled after 68 reported salmonella infections. Health agencies are warning that the contaminated cucumbers may still be in people’s refrigerators and should not be eaten.
