Cyclospora found at Mexican farm linked to lettuce outbreak, FDA says
Two environmental samples tested positive, and the FDA said patient reports and traceback data strongly linked the outbreak to recalled lettuce.
- On Friday, the Food and Drug Administration concluded its investigation into a summer Cyclospora outbreak, linking illnesses to recalled shredded iceberg lettuce from Taylor Farms de Mexico.
- During the probe, investigators found the Cyclospora parasite at Taylor Farms de Mexico's processing facility and at a lettuce farm in Mexico, with two environmental samples testing positive.
- The Centers for Disease Control and Prevention declared the outbreak over September 11, with 19,883 laboratory-confirmed cases of cyclosporiasis and two deaths reported by September 14.
- Confident that all recalled lettuce is off the market, the FDA announced a 10-point plan to prevent similar outbreaks ahead of the 2027 growing season, including expanded monitoring and grower outreach.
- Investigators could not definitively determine how contamination occurred, though the FDA traced lettuce to multiple Mexican farms and a processing facility supplied by Taylor Fresh Foods.
