CDC update on McDonald’s Salad outbreak

  • On July 12, 2018, the Iowa Department of Public Health and the Illinois Department of Public Health reported an increase in cases of cyclosporiasis among people who ate salads sold at McDonald’s fast-food chain restaurants. CDC also has received reports of sick people who ate McDonald’s salads from locations in Indiana, Kentucky, Minnesota, Missouri, Nebraska, Ohio, South Dakota, and Wisconsin.
    • Cyclospora cayetanensis is a single-celled parasite that causes an intestinal infection called cyclosporiasis.
  • McDonald’s is cooperating with the investigation and has voluntarily stopped selling salads in more than 3,000 locations in the following 14 states: Illinois, Indiana, Iowa, Kentucky, Michigan, Minnesota, Missouri, Montana, Nebraska, North Dakota, Ohio, South Dakota, West Virginia, and Wisconsin.
    • Because of the proactive actions McDonald’s took to remove the affected salads from the locations in these states, there likely is not ongoing risk to consumers who eat at those

  • Important advice for consumers:
    • If you have eaten a salad from a McDonald’s restaurant in Iowa, Illinois, Indiana, Kentucky, Minnesota, Missouri, Nebraska, Ohio, South Dakota, or Wisconsin since mid-May (on or after 5/20/2018) and you developed diarrhea, see a healthcare provider to be tested for Cyclospora infection and to be treated if you are sick.
    • Do not eat leftover salads from McDonald’s restaurants that were purchased in Iowa, Illinois, Indiana, Kentucky, Minnesota, Missouri, Nebraska, Ohio, South Dakota, or Wisconsin. Throw them away.
  • This investigation is ongoing. CDC will provide updates when more information is available.
  • Read the related statement from the U.S. Food and Drug Administration.
  • At this time, there is no evidence to suggest that this cluster of illnesses is related to the Cyclospora outbreak linked to Del Monte fresh produce vegetable trays.
