Tribal public health officials are among those reassuring citizens about the safety of their food as reports of new cases of cyclospora infections continue to rise. Michigan continues to be a hotspot with state officials reporting more than 11,000 cases. The actual number is likely much higher than that. One hurdle in tracking the cyclosporiasis outbreak is it has a long incubation period and it can’t be traced through the genetic markers that some other food-borne illnesses have. The infections are traced mainly to tainted lettuce from Mexico. Nearly all other states are also reporting cyclospora cases, many of them from a variety of sources.
