Jeremy C. Owens

McDonald's Corp. (mcd) shares dipped in the extended session Thursday after the Iowa Department of Public Health announced that it was investigating "an increase in Cyclospora infections that appear to be connected to consumption of McDonald's salads." The department said that it had identified 15 people in that state who had become ill with such an infection after eating McDonald's salads in late June and early July. In a separate announcement, Illinois public health officials said it had confirmed 90 cases of cyclosporiasis. "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," Dr. Patricia Quinlisk said in the announcement.
