Cucumbers sold to Costco, Walmart, Wegmans and Albertsons have since been recalled for possible contamination with salmonella.

Rochester, N.Y.-based Wegmans Food Markets Inc. released recall information about the affected cucumbers, urging customers to either throw them away or return them to the store for a full refund. Walmart, meanwhile, released a list of stores across 15 states that carried the affected cucumbers.

Sixty-eight people have been sickened and 18 have been hospitalized in a salmonella outbreak linked to whole cucumbers sold in 26 states and parts of Canada.
