Federal health officials are investigating a large, multistate outbreak of cyclosporiasis — an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis — that has been traced to shredded iceberg lettuce served at Taco Bell restaurants. The Centers for Disease Control and Prevention and the Food and Drug Administration have tied the illnesses to Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia, and have told people in those states not to eat the shredded iceberg lettuce served there.
As of July 16, 2026, the CDC had counted more than 1,644 illnesses and 94 hospitalizations connected to this outbreak, with no deaths reported. Those figures reflect only the cases tied specifically to Taco Bell. The broader national picture this summer is far larger: the CDC has confirmed roughly 1,645 domestically acquired cyclospora cases across 34 states since May 1, with more than 5,100 additional cases still under review and state health departments reporting totals that push the count toward 7,000. Michigan has been hit hardest by a wide margin.

The FDA’s traceback work pointed to a single supplier of iceberg lettuce grown in Mexico. Federal agencies have not publicly named that supplier, but The Washington Post, CNN, and NBC News have each reported — citing people familiar with the investigation — that the company is California-based Taylor Farms. Taco Bell has said it is voluntarily pulling the lettuce from that supplier in the affected states and removing it from its supply chain nationwide.
Some early coverage described this as a recall. It isn’t, at least not yet. The CDC has issued no formal recall, and the investigation remains open while the FDA works to determine whether the same lettuce reached other restaurants, grocers, or distributors. Anyone following the story should watch for updates from the CDC and FDA as it develops.
The parasite behind the outbreak

Cyclospora is not a bacterium or a virus. It is a single-celled parasite that spreads through human waste and reaches food or water when sanitation breaks down somewhere along the way — in the field, at harvest, in processing, or in handling. Fresh produce that people eat raw, like leafy greens and berries, is a recurring culprit, and that is part of what makes these outbreaks so stubborn. The FDA has found that the chlorine washes and antimicrobial treatments used on produce do not reliably kill the parasite, and rinsing lettuce at home does not guarantee its removal either.

The illness usually announces itself with frequent, watery diarrhea that can be severe and has a habit of easing up and then returning. Loss of appetite and noticeable weight loss are common, along with stomach cramps, bloating, gas, nausea, and fatigue; some people also have vomiting, body aches, headache, or a low fever. Symptoms typically begin about a week after exposure, though they can appear as early as a couple of days or as late as two weeks or more. Left untreated, cyclosporiasis can drag on for weeks — sometimes more than a month — and that on-again, off-again pattern is one of the things that sets it apart from the short-lived food poisoning most people are used to. Dehydration and other complications send some patients to the hospital.
What to do if you got sick
If you developed these symptoms after eating shredded iceberg lettuce at one of the affected Taco Bell locations — or after eating other produce you think may be tied to this outbreak — see a healthcare provider. This is one illness where it pays to speak up: routine stool tests do not always screen for Cyclospora, so tell your provider about the possible exposure and ask directly whether testing for the parasite makes sense. Cyclosporiasis is treatable, usually with a course of antibiotics along with rest and fluids.
It also helps to hold on to the ordinary paper trail while it still exists. Keep your receipts, order confirmations, and any food packaging, and write down what you ate and where in the two weeks before you got sick, while it is still fresh in your mind. Save your medical records, lab results, and anything documenting time missed from work. And if a state or local health investigator reaches out, cooperate with them — that information helps trace the source, and the same records can matter a great deal if you later decide to pursue a claim.
Who can be held responsible
Contaminated food usually passes through a lot of hands between the field and the plate, and responsibility can rest with any of them — the grower, the processor or packer, the distributor, the restaurant, or the retailer — depending on where the contamination happened and what the evidence shows. Sorting that out takes medical proof, laboratory confirmation, purchase and restaurant records, the product-tracing data that regulators develop, and often expert analysis. It also takes moving reasonably quickly, because the evidence that connects a specific illness to a specific source has a way of disappearing.
This supplier is not new to these questions. Taylor Farms has been publicly linked to earlier foodborne-illness outbreaks, including E. coli cases tied to its onions in 2024 and a cyclospora outbreak connected to its lettuce back in 2013 — the kind of history that matters when the question is whether a company did enough to keep its product safe.
How Jenner Law can help
We know a foodborne illness is rarely just a rough few days. For some people it means a hospital stay, weeks of symptoms, real medical bills, lost income, and health problems that linger — and it happened because food they trusted turned out not to be safe.
Our firm has represented people harmed by contaminated food in individual cases, class actions, and larger coordinated litigation. We are at home with the medical and scientific questions these cases turn on, and we do the work of identifying every company in the chain — grower, processor, supplier, restaurant, retailer — that may bear responsibility. Depending on the case, a recovery can cover medical expenses, lost wages, pain and suffering, and other harm caused by the contamination.
If you or someone in your family came down with cyclosporiasis or another serious gastrointestinal illness after eating at Taco Bell, or after eating lettuce or produce that may be connected to this outbreak, we would be glad to talk it through with you. The consultation is free and confidential, and we handle these cases on a contingency basis — no fees and no case expenses unless we recover for you.
