Fresh cucumbers are the latest food safety recall. The Centers for Disease Control and Prevention and the U.S. Food and Drug Administration are warning consumers to check their counters and refrigerators for whole fresh American cucumbers after at least 68 people in 19 states became sick from salmonella.

More than 65 people are sick with the illness so far. These are the signs and what you should do if you have the produce in your fridge.

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