A former Food and Drug Administration (FDA) official, Frank Yiannas, has raised alarms about the federal response to a widespread cyclospora outbreak in the U.S. Yiannas, who served as the FDA’s deputy commissioner for food policy and response from 2018 to 2023, criticized the handling of the crisis in an interview with Politico.
Yiannas called for an independent assessment of the government’s response, highlighting issues such as high illness rates, consumer confusion, and insufficient federal coordination. He emphasized the need to find facts to strengthen the system rather than pointing fingers at any specific agency.
“My point is not to find fault, but to find facts on how we can further strengthen the system,” Yiannas noted.
His comments come as health officials continue investigating multiple cyclospora outbreaks, including a large multistate outbreak linked to recalled iceberg lettuce from Taylor Farms de Mexico. A recent false positive finding in a Taylor Farms lettuce sample added to the confusion and raised questions about the investigation’s integrity.
Yiannas has also suggested improvements in communication and coordination among agencies to prevent such errors from recurring. The outbreak has stirred significant concern, with at least 1,947 cases linked to Taylor Farms’ shredded iceberg lettuce. The CDC reported 4,173 lab-confirmed cases by July 24, with many more suspected cases still unconfirmed.
Background and Historical Context
Past cyclospora outbreaks have been traced back to fresh produce like salad mix and cilantro, with significant events occurring in 2013, 2018, and 2019. Cyclospora itself, a parasite causing cyclosporiasis, leads to severe intestinal symptoms such as diarrhea, cramps, and fatigue.
The parasite thrives in contaminated food or water and requires environmental maturation before becoming infectious, complicating efforts to trace outbreaks. Treatment usually involves antibiotics, and while most recover fully, vulnerable populations are at higher risk for severe outcomes.
Current Efforts and Recommendations
Federal investigators are focusing on the link to Taylor Farms’ lettuce, which led to a recall of iceberg lettuce on July 17. The CDC advises avoiding the recalled products and following safety guidelines.
Although federal monitoring for cyclospora became optional in 2025, experts argue for stronger surveillance to manage outbreaks better. Consumers are advised to wash produce, check for recalls, and seek medical care if symptoms develop.
Taylor Farms, committed to food safety, has taken proactive measures including a voluntary recall and suspension of production in Mexico. Independent experts are reviewing their safety practices, and the company remains transparent as investigations progress.
Taylor Farms declared no confirmed positive samples for Cyclospora as of July 24 and reassured confidence in their food safety protocols.
