Cyclosporiasis concerns grow in CA as illness spreads

Health officials are pointing to lettuce or salad greens as a potential source behind the outbreak of cyclosporiasis that is spreading throughout the state. Consumers are strongly advised to take special care when purchasing salad greens, including purchasing the whole head of lettuce instead of the bagged variety, and discarding the outer layers. They also ask that people cook when possible, heating the food to temperatures that kill cyclospora, the parasite responsible for the gastrointestinal illness.
