Chelan-Douglas Health District (CDHD) is monitoring a multistate cyclosporiasis outbreak affecting 34 states, though no cases have been identified in Washington State as of July 2026.

CDHD advises residents to wash produce thoroughly, avoid eating bruised vegetables, and refrigerate cut fruits within two hours to reduce risk. Symptoms include watery diarrhea, abdominal cramps, and fatigue, with CDC suggesting shredded lettuce as a potential source.

The health district will update the public if cases emerge in Washington, urging healthcare providers to consider Cyclospora testing for persistent diarrhea.
