A state is now reporting 700+ cases of ‘explosive’ diarrhea linked to parasite. Here’s what we know
At least 18 states have reported cyclosporiasis cases as of Monday, with New York confirming more than 100 infections and New Jersey reporting between 1 and 10, according to the Centers for Disease Control and Prevention.
The parasitic intestinal illness is caused by Cyclospora cayetanensis, which spreads through contaminated food or water rather than person-to-person transmission, according to the CDC.
Symptoms include frequent, watery diarrhea described as "explosive," alongside abdominal cramps, fatigue, and nausea that can persist for weeks or months without treatment, according to the CDC.
Case counts in Michigan reached 572 by July 4, but state officials note that complex food distribution networks—where produce is grown in one state, processed in another, then distributed nationally—complicate tracing the source.
The CDC advises cooking raw foods to at least 158°F to kill the parasite, while also recommending thorough washing of fresh produce and scrubbing firm fruits and vegetables with a clean brush to reduce exposure risk.
