Multistate Cyclosporiasis Outbreak Investigation Points to Lettuce or Salad Greens

Federal and state health officials are investigating a multistate outbreak of cyclosporiasis, a gastrointestinal illness caused by a parasite. Current findings suggest lettuce or salad greens as a potential source, though other food items are not ruled out. The outbreak has sickened thousands and hospitalized over 80 people across more than 30 U.S. states.
