Milord et al write in the current issue of Epidemiology and Infection about an outbreak of Cyclospora cayetanensis amongst 250 patrons who ate at a Quebec restaurant in June 2005.

Cyclospora sp. was observed in the stools of 20 cases and 122 probable cases were identified.

Contaminated fresh basil originating from a Mexican farm, used to prepare an uncooked appetizer, was identified as the source.
