A diarrhea-causing parasite known as cyclospora that causes “explosive diarrhea” is rapidly spreading across the nation - with Michigan being hit the hardest. Exposure to the parasite by eating or drinking contaminated produce or water causes cyclosporiasis, an explosive stomach bug that can leave people feeling ill for more than a month.
