The Return of Cyclospora in 1997: Another Outbreak of Cyclosporiasis in North America Associated with Imported Raspberries

Figure 2. *Includes three events (one traced to Guatemalan exporter A and two traced to Guatemalan exporter B) for which there
might have been additional branches of the tracebacks without well-documented data; only well-documented data are included
here. A farm was considered linked to an event if it contributed to a shipment of raspberries that could have been used at
that event.
Tracebacks of sources of raspberries served at events associated with clusters of cases of cyclosporiasis in North America
in 1997.†
