Twenty-six people have been sickened, with nine of them being hospitalized, due to a salmonella outbreak linked to cucumbers sold across the country. Now some cucumbers are being recalled.

The outbreak, which was traced to a grower in Florida, has spread to 18 states, according to the C.D.C. Several distributors and stores, including Target, have recalled products containing cucumbers.

Federal health officials say at least 45 people in 18 states have been sickened in an expanding salmonella outbreak tied to recalled cucumbers.
