The nationwide cyclospora outbreak is very likely a result of sewage contamination in the food supply, according to scientific researchers and public health officials.
The parasite’s spread can become a self-perpetuating cycle. Cyclospora is found only in humans, where it replicates in the intestinal tract, causing severe diarrhea. The organism reproduces by releasing oocysts, which are excreted in those human feces. In the U.S., feces usually end up in sewage systems.
