A parasitic outbreak tracing back to lettuce fields in central Mexico has sickened thousands of Americans, turning a celebrated agricultural region into a cautionary emblem of the invisible risks woven into modern food supply chains. Cyclospora, a waterborne parasite capable of weeks of intestinal suffering, traveled undetected across international borders inside the very produce that has long nourished American tables. The episode asks an old and unresolved question: in a world where a single field can feed millions, who bears responsibility when the harvest carries harm?
