The investigation into the multistate outbreak of Listeriosis linked to packaged salads produced at Springfield, Ohio Dole Processing Facility has grown to 18 cases with the addition of two cases from Ohio and an additional case from Missouri in the past month, according to the Center for Disease Control and Prevention (CDC).
Eighteen people infected with the outbreak strain of Listeria have been reported from nine states since July 5, 2015. All 18 people were hospitalized, including one person from Michigan who died as a result of listeriosis. One illness was reported in a pregnant woman.
The number of ill people reported from each state is as follows: Connecticut (1), Indiana (1), Massachusetts (1), Michigan (4), Missouri (2), New Jersey (1), New York (5), Ohio (2), and Pennsylvania (1).
Epidemiologic and laboratory evidence indicate that packaged salads produced at the Dole processing facility in Springfield, Ohio and sold under various brand names are the likely source of this outbreak.
Although the investigation began in September 2015, the source of these illnesses wasn’t known until January 2016 when a laboratory result from a packaged salad collected in Ohio linked the illnesses to the Dole processing facility in Springfield, Ohio.
On January 27, 2016, Dole voluntarily recalled all salad mixes produced in the Springfield, Ohio processing facility.
