Federal and state health officials are looking into whether Taco Bell restaurants may have played a role in a major cyclospora outbreak, as investigators examine lettuce and other salad ingredients as a possible source of contamination. Two sources familiar with the investigation told The Washington Post that agencies are reviewing whether Taco Bell locations could be connected to the spread of cyclosporiasis, a gastrointestinal illness caused by a microscopic parasite. The Michigan Department of Health and Human Services said Monday that lettuce or salad greens are currently considered a possible source of the outbreak. thepostmillennial.com
