Cyclospora outbreak investigations are notorious for being very difficult to pinpoint the vehicle and/or the source.
Sometimes the food vehicle/source is identified, sometimes not. Since 2000, about 20 cyclospora outbreak investigations came up empty concerning this information.
The current outbreak of cyclosporiasis in the US has topped 1,000 cases year-to-date (1031 to be exact) with a little more than half (578) being locally transmitted from 36 states.
As of Sept. 20, federal health officials report no specific vehicle of interest has been identified, and investigations to identify a potential source (or sources) of infection are ongoing.
