2016 Salmonella Oslo Outbreak Linked to Persian Cucumbers
Between March and April 2016, 14 consumers in eight states became ill with Salmonella Oslo after apparently eating contaminated cucumbers. After epidemiologic, traceback, and laboratory investigations, the U.S. Centers for Disease Control (CDC) now says the source of the outbreak was Persian cucumbers. The produce was sold at a national grocery chain that has yet to be named.
Besides CDC, the investigation also included a collaboration with the U.S. Food and Drug Administration (FDA), the Canadian Food Inspection Agency, and health officials in the affected states of Massachusetts, Michigan and Minnesota. While two Persian cucumber suppliers were identified in Canada in connection to the outbreak, no single grower has been identified. However, CDC states that growers who could have supplied the contaminated cucumber may have been located in Canada, Dominican Republic, and Mexico. Still, FDA says they were unable to fully traceback the pathogen. They agency also has not been able to confirm cucumbers as the vehicle, as there were no positive samples tested.
