National health officials announced Friday that the largest cyclospora food‑borne outbreak in U.S. history has been declared over. The Federal Food and Drug Administration (FDA) confirmed that every batch of recalled iceberg lettuce linked to the multistate surge has been removed from the market, and on‑site inspections at the Mexican processing facilities have concluded.
Scope of the outbreak
Nearly 13,000 reported cyclospora cases were tied directly to the lettuce outbreak, representing the bulk of an unprecedented rise in the parasitic diarrheal illness this year. Since May 1, the government has logged almost 20,000 lab‑confirmed cases—more than 16 times the number reported during the same period last year. An additional 6,100 suspected cases have been reported.
The previous high‑water mark for cyclospora infections was 2019, when roughly 4,700 illnesses were recorded nationwide. This year’s surge was driven primarily by an outbreak in 21 states linked to iceberg lettuce grown in central Mexico and distributed to major restaurant chains, including those owned by Yum Brands.
How the contamination occurred
Experts say the parasite spreads through human feces and can contaminate produce when it contacts soil or water that has been polluted. “This contamination can happen if produce is grown in soil or comes into contact with water that has been contaminated,” explained Ellen Shumaker, director of outreach for the North Carolina State University food‑safety program Safe Plates.
Initial investigations focused on lettuce served at a fast‑food chain, but federal officials later identified Taylor Farms as the source. The company recalled thousands of packaged salad products that combined iceberg lettuce with other vegetables. Those products had been shipped to national restaurant chains, prompting a swift recall.
FDA response and next steps
The FDA has completed its on‑site inspections and sample collection at the Mexican growers and processing facility. While samples are still pending laboratory analysis, the agency emphasized that the recall and inspection efforts have effectively halted further spread of the parasite.
Officials also highlighted a broader concern: fewer international inspections are being conducted, which could allow contaminated produce to reach American tables. The agency pledged to review its inspection protocols to better protect consumers.
Impact on families and communities
Michigan bore the brunt of the outbreak, reporting the highest number of cases and the two U.S. deaths linked to the illness. Cyclospora typically causes watery diarrhea with frequent, sometimes explosive bowel movements, a condition that can be especially distressing for families with young children.
Health professionals urge anyone experiencing prolonged diarrhea, especially after consuming raw produce, to seek medical attention. Treatment is available, and early diagnosis can reduce the severity of symptoms.
Looking ahead
While the immediate threat has been contained, questions remain about how the contamination originated. Ongoing analysis of the collected samples will aim to clarify the pathway from sewage to the lettuce fields.
The CDC continues to monitor cyclospora cases and advises the public to practice safe food handling, including thorough washing of fresh produce and proper kitchen hygiene.
