Michigan and at least two dozen other states are reporting rising cases of cyclosporiasis, a foodborne infection caused by a stomach parasite that causes severe and sometimes explosive diarrhea. More than 1,000 infections have been reported as of July 9, according to STAT, a health and medical news source which cited Associated Press reports. Here's where cyclosporiasis has been reported and how to protect yourself. To reduce the risk of cyclosporiasis, health officials have issued guidance aimed at anyone involved in preparing, processing or serving fresh produce:. * Sanitize display cases and refrigerators used to store fresh produce. * Clean and sanitize cutting boards and tools used with fresh produce. While most bacterial foodborne illnesses resolve within a few days, cyclosporiasis can lead to gastrointestinal symptoms that persist for weeks or even longer, according to the Food and Drug Administration.
