Retrospective cohort studies of clusters of cases associated with events (such as banquets) and traceback investigations of sources of implicated produce.
United States and Canada.
Persons who attended events associated with clusters of cases of cyclosporiasis.
Identification of clinically defined or laboratory-confirmed cases of cyclosporiasis and risk factors for infection.
41 clusters of cases were reported in association with events held from 1 April through 26 May in 13 U.S. states, the District of Columbia, and 1 Canadian province.
The clusters comprised 762 cases of cyclosporiasis, 192 (25.2%) of which were laboratory confirmed.
In addition, 250 laboratory-confirmed sporadic cases were reported in persons who developed gastrointestinal symptoms from April through 15 June, for a total of 1012 cases.
Fresh raspberries were the only food common to all 41 events and were the only type of berry served at 9 events (22.0%). Statistically significant associations between consumption of raspberry-containing items and cyclosporiasis were documented for 15 events (40.5% of 37). (...)
