FDA closes cyclospora investigation, finds parasite in Mexico but not the cause
The FDA has closed its investigation into the largest U.S. cyclosporiasis outbreak, confirming the parasite was present at Taylor Farms' Mexican processing site and in the fields where the implicated lettuce was grown. However, the agency stated it could not determine how the contamination occurred. The outbreak sickened over 12,000 people across 21 states and resulted in two deaths. While the CDC previously declared the outbreak over as cases declined, this FDA finding provides environmental confirmation of the parasite's presence but leaves the specific transmission mechanism unresolved.
