On May 20, 2016, the CDC announced that they have concluded their investigation into the outbreak of Salmonella caused by Wonderful Pistachios. A total of 11 people were sickened in the outbreak by either Salmonella Montevideo or Salmonella Senftenberg. Nine states were affected by the outbreak, including Connecticut with 1 case, Georgia with 1 case, Meryland with 1 case, Michigan with 2 cases, Minnesota with 1 case, North Dakota with 1 case, New York with 1 case, Virginia with 1 case, and Washington with 2 cases. There were two hospitalizations reported, and no deaths.
There was a recall issued in relation to this outbreak. On March 9, 2016 Wonderful Pistachios issued a voluntary recall for several varieties of pistachios. March 9 was also the day that the CDC announced its investigation. Many different lots of product were affected by the outbreak, and those lots were identified by a 13 number lot code found on the bottom of the package. Pistachios affected by the outbreak and recall were distributed to retail locations in the United States, Canada, Mexico, and Peru. Although products affected by the recall can no longer be found in retail stores, these pistachios may still be in the homes of consumers.
