U.S. health officials declare end of largest national Cyclospora outbreak

What This is

• U.S. health officials declared the nation’s largest recorded Cyclospora outbreak over.
• The outbreak was tied to about 12,883 illnesses across 21 states, with about 570 hospitalizations and two deaths reported.
• Investigators linked many illnesses to processed iceberg lettuce traced to Taylor Farms de Mexico and issued recalls.
• Federal officials said the recalled lettuce is no longer in stores or restaurants and does not pose a current risk.
• Investigators have not fully determined how the lettuce became contaminated, with reporting often pointing to fecal or sewage contamination.
• Officials also reported a much larger nationwide rise in lab-confirmed Cyclospora cases this year, beyond the lettuce-linked outbreak.
• The FDA ended on-site inspections at the growers and processing facilities in Mexico, while laboratory testing and the investigation continue.

Why This Matters

• The outbreak raises questions about how well U.S. agencies can oversee imported food, especially when inspections and public health capacity are under strain.
• It shows the tradeoff regulators face between fast public warnings and avoiding broad fear that can hurt farmers, restaurants, and shoppers.
• Official “outbreak over” calls can still be followed by new case reports because illness and testing data often arrive late.
