Cyclospora Lawyer

If a Cyclospora infection left you with weeks of watery diarrhea, cramping, and fatigue that kept returning, you may be able to hold the grower, importer, or restaurant responsible.

As of January 2026, the CDC had counted about 1,180 cases of cyclosporiasis acquired in the United States during 2025, and it acknowledges the real total is higher because the parasite is missed whenever providers run routine stool panels instead of targeted Cyclospora testing. That underdiagnosis gap matters in litigation: every patient whose infection was never confirmed is a case that cannot be filed. The delayed onset creates an additional challenge. Because symptoms typically begin about a week after exposure, restaurants may discard fresh ingredients, contaminated produce lots may ship to other states, and purchase records become harder to locate before patients realize they are sick. Early legal and medical documentation is critical to building a viable claim.

Cyclosporiasis requires specific stool testing that is not part of routine ova and parasite panels. CDC clinical guidance identifies acid-fast staining and PCR as diagnostic methods and notes that multiple specimens collected on different days may be needed. That diagnostic gap is the first line of attack defense teams use: no confirmed infection, no identifiable source, no provable exposure window. A positive Cyclospora lab result closes the infection argument and begins building the clinical record that supports damages, including specialist referrals, treatment costs, and follow-up testing. Patients who received only a general stool culture should seek targeted follow-up, especially if symptoms have returned after initial improvement.

Recent outbreak investigations demonstrate how causation is established. In 2025, FDA announced a Cyclospora outbreak linked to parsley from Puebla, Mexico: 69 reported illnesses across multiple states and a supply chain that had already cleared commerce before the advisory was issued. The Alabama restaurant outbreak published in MMWR linked illness to cilantro with an odds ratio of 40.9 in case-control analysis, then traced the supply chain to a Texas importer sourcing from Mexico and identified failures in procurement controls. That chain of evidence, from a patient’s stool result to an importer’s invoices, is exactly what a Cyclospora lawsuit must reconstruct. One biological characteristic of Cyclospora supports the focus on food sources: oocysts shed in stool are not immediately infective and require environmental time to sporulate, making direct person-to-person transmission unlikely in most U.S. fact patterns and keeping investigative focus on contaminated food and handling systems.

Ron Simon & Associates is a Cyclospora law firm with an exclusive focus on food poisoning and foodborne illness litigation. Our Cyclospora outbreak lawyers have filed lawsuits in prior produce-linked outbreaks. We build claims the same way public health investigators do: lab confirmation, symptom onset timeline, ingredient-level traceback, and documentation of supply-chain control failures at the grower, importer, or distributor level. If you have been diagnosed with Cyclospora, begin preserving evidence immediately. Save lab results, medical records, receipts, loyalty app history, and delivery confirmations from the week before symptoms began, along with any remaining produce packaging. Document every missed workday and follow-up visit, then contact our team for a free case evaluation. You pay us nothing unless we recover compensation for you.
