(CNN) One person has died and 12 others are hospitalized after eating packaged salads linked to a listeria outbreak.
The Centers for Disease Control and Prevention said Friday that the salads were sold under a variety of names and came from a processing facility in Springfield, Ohio, run by Dole.
The dozen who were hospitalized come from six states -- Massachusetts, Michigan, New Jersey, New York, Pennsylvania and Indiana. The fatality was in Michigan. Reports about these infections started coming in July.

An investigation began in September, the CDC said, but the source of the infections was unknown until this month when lab tests confirmed listeria in salads collected from the Springfield facility.
