BISMARCK, N.D. (AP) — The North Dakota Department of Health says at least six people in the state have been sickened with an illness associated with bagged salad mixes. The cases are part of a larger outbreak occurring in Midwestern states. All six in North Dakota ate Marketside brand salad. The mixed salads were sold at Hy-Vee, Jewel-Osco and Aldi grocery stores and are contaminated with cyclospora, a parasite that can cause flu-like symptoms. The other brands are Hy-Vee and Little Salad Bar. Consumers in 12 states are affected by a recall of the products which have sickened dozens of people, including some who were hospitalized. The government investigation found that the mix, which is produced by Fresh Express, was also sold at Walmart stores. The mixes are under different brand names at the different stores.
