Iowa and Ilinois have reported over 100 cases collectively.
Both the Iowa and Illinois Departments of Public Health have reported cases of the cyclospora infection related to the consumption of McDonald's salads. Cyclospora cayetanensis is an infection of the small intestine that causes frequent bowel movements and watery diarrhea.
There was not one type of salad that was thought to cause the infection. Officials believe that the infection resulted from tainted lettuce that could be in any of the salads on the menu. McDonald's said in a statement that they are looking to resolve the issue and have, in the meantime, stopped selling all salads at 3,000 locations.
