LINCOLN, Neb. (AP) – State authorities have confirmed that four Nebraska listeria cases have been linked to an outbreak connected to Colorado-grown cantaloupe. Another possible case is being investigated. A news release from the Nebraska Department of Health and Human Services says all four of the Nebraskans are elderly and all have been or are currently hospitalized. Douglas County has two of the cases. The others are from Gage and Hitchcock counties. Four people have died in the outbreak: one in Colorado and Oklahoma, two in New Mexico. Federal authorities say the outbreak has spread to 10 states and at least 35 people, including the four in Nebraska. The illnesses have been traced to fruit from Jensen Farms in Holly, Colo. The company has recalled its Rocky Ford-brand cantaloupes.
