DES MOINES, Iowa – An investigation into McDonald’s salads is now underway in Iowa.
The state’s Department of Public Health says an increase in Cyclospora infections appears to be connected to eating that food.
"This summer there have been several clusters of Cyclospora illness associated with various foods that are commercially available. This week IDPH has identified 15 Iowans who ate McDonald's salads in late June to early July prior to getting ill,” says sate medical director Dr. Patricia Quinlisk. “Anyone who ate these salads since the middle of June and who developed diarrhea, especially watery diarrhea and fatigue, should see their health care provider and get tested for Cyclospora to ensure an accurate diagnosis and appropriate treatment.”
The Illinois Department of Public Health says it has notice a similar increase in Cyclospora associated with McDonald’s salads.
Cyclospora is a parasite commonly found in developing countries but several outbreaks have occurred in the U.S. in the past several years, especially during the summer months.
Symptoms of Cyclospora infection include:
• Frequent watery diarrhea
• Loss of appetite and weight
• Cramping, bloating and/or increased gas
• Nausea (vomiting is less common)
• Low-grade fever
It may take a week or more for symptoms to show up after consuming contaminated food.
Officials say the fast-food company has been fully cooperating with the investigation and McDonald's and involved federal partners are determining what further steps should be taken.
