The Iowa Department of Public Health (IDPH) on Thursday said it was investigating a rise in Cyclospora infections, likely due to the consumption of a salad served by McDonald’s Corp.

Symptoms of Cyclospora, a parasite common during the summer months, include frequent watery diarrhea, loss of appetite and weight, and nausea.

Shares of McDonald’s were down 1.4 percent in after-hours trading.

McDonald’s did not immediately respond to a request for comment.
