The FDA and CDC are investigating a multistate outbreak of Cyclospora illnesses potentially linked to bagged garden salads sold at ALDI, Jewel-Osco and Hy-Vee stores.
They are recommending consumers not eat ALDI Little Salad Bar Brand Garden Salad, Jewel-Osco Signature Farms Brand Garden Salad and Hy-Vee Brand Garden Salad.
The FDA says it has initiated a traceback investigation to determine supplier and distributor information to find the cause and source of the outbreak.
Cyclospora is a microscopic parasite that can affect the intestinal tract and cause diarrhea, according to the CDC.
Jewel-Osco announced Saturday it's voluntarily recalling its 12-ounce bagged Signature Farm Garden Salad sold in its stores in Illinois, Indiana and Iowa.
They have "best if used by" dates of May 16 through July 4 and a UPC code of 21130 98135.
Jewel-Osco is asking consumers who have purchased the salads to discard or return them for a refund.
Jewel-Osco customers can also call 1-877-723-3929.
