Cyclosporiasis associated with imported raspberries, Florida, 1996.
Unt 1995, infection with Cyclospora cayetanenis, a parasite that causes gastroenteritis, was diagnosed in the US primarily in overseas travelers ; its modes of transmission were largely unknown.
In 1995,45 cases of cyclosporiasis were diagnosed in Florida residents who had no history of recent foreign travel, but an investigation could not pinpoint a source for the parasite.
In 1996, a North American outbreak of cyclosporiasis resulted in more than 1400 cases, 180 of them in Florida, The authors investigated the 1996 Florida outbreak to identify the vehicle of transmission.
The authors conducted a matched case-control study in which each of 86 laboratory-confirmed sporad cases was matched with up to four controls.
They also nvest gated nine clusters of cases associated with common meals and attempted to trace implicated foods to their countries of origin.
In the case control study, eating raspberries was strongly associated with cyclosporiasis (matched odds ratio=31.9 ; 95% confidence interval [CI] 7.4,138.2).
In the cluster investigation, raspberries were the only food common to all nine clusters of cases : a summary analysis showed a strong association between consumption of raspberries and confirmed or probable cyclosporiasis (risk ratio=17.6 : 95% Cl 1.9,188.8).
Guatemala was the sole country of origin for raspberries served at six of nine events. (...)
