Diarrhea-causing parasite that can contaminate raw produce causing misery across several states

A Cyclospora parasite causing severe diarrheal illness is contaminating raw produce and leading to outbreaks across several U.S. states, with Michigan reporting over 600 cases and New York state reporting 107 cases since May 1. The CDC notes rising summer cases but no single multistate outbreak, emphasizing the parasite spreads via contaminated water on crops and can be killed by heat. Health officials advise thorough washing of produce and surfaces, though bleach is ineffective.
