The Taylor Farms cyclospora outbreak 2026 is shaping up to be the largest cyclosporiasis outbreak in United States history. Shredded iceberg lettuce supplied to Taco Bell by Taylor Farms has been identified as a potential source of contamination in a multistate outbreak of cyclosporiasis, a parasitic intestinal illness, according to sources familiar with the investigation cited by CNN, NBC News, and The Washington Post on July 16. The CDC had confirmed at least 1,645 laboratory cases of domestically acquired cyclosporiasis since May 1, with more than 5,100 additional cases under investigation, for a potential total approaching 7,000. At least 141 people have been hospitalized nationally. Michigan has been hit hardest with more than 4,300 confirmed cases in the state alone, alongside 102 hospitalizations. Taco Bell confirmed on Thursday that it has voluntarily removed potentially impacted lettuce from its supply chain nationwide indefinitely, replacing it with an alternative supplier in affected states within 24 hours.
What Is Cyclospora and Why Is This Outbreak Unusual
The scale of this outbreak requires context about the parasite involved and its typical epidemiology.
Cyclospora cayetanensis is a microscopic single-celled parasite that causes cyclosporiasis, a diarrheal illness. Once a person ingests Cyclospora oocysts through contaminated food or water, the parasite infects the small intestine. Symptoms typically begin one week after ingestion and include watery, sometimes explosive diarrhea; loss of appetite; weight loss; stomach cramps; nausea; fatigue; and low-grade fever. The illness can persist for weeks or months if untreated.
The unusual epidemiological feature of this outbreak is its scale relative to normal baseline. Confirmed cases are more than six times higher than they were at this time last year, according to CDC data published Tuesday. The 1,645 confirmed cases represent only the laboratory-confirmed fraction of the outbreak. The additional 5,100-plus cases under investigation, many of which may be confirmed in the coming days as laboratory results return, mean the true scope of illness is potentially far larger.
If the total case count approaches or exceeds 7,000, this would represent the largest cyclosporiasis outbreak in US recorded history, surpassing the 2018 outbreak linked to Del Monte vegetable trays and the 2013 outbreak linked to Taylor Farms de Mexico salad mix distributed to Olive Garden and Red Lobster restaurants in Iowa and Nebraska.
The Taco Bell and Taylor Farms Connection: What Sources Are Saying
The investigative thread connecting the outbreak to a specific supplier and restaurant chain requires careful presentation because it rests on anonymous sourcing at this stage.
Investigators have identified shredded iceberg lettuce supplied to Taco Bell restaurants by Taylor Farms as a potential source of contamination in the multistate outbreak, according to two individuals familiar with the investigation cited by The Washington Post. CNN cited a source familiar with the investigation reaching the same conclusion. NBC News independently corroborated the reporting through an anonymous source, citing the FDA investigation of Taylor Farms iceberg lettuce supplied to Taco Bell. The FDA told NBC News the investigation is ongoing.
The outbreak linked to the lettuce is considered a regional outbreak centered in the Midwest. The CDC has identified at least 400 cases associated with the outbreak across four states: Michigan, Ohio, West Virginia, and Kentucky. According to the CNN source, those are the states where the affected Taco Bell locations are. NBC News reported a fifth state, Indiana, as also affected.
The Post’s reporting says that when the FDA asked Taco Bell where its lettuce came from in those four states, the answer was Taylor Farms. A search of the FDA’s recalls list as of July 16 showed no active recalls for Taylor Farms. The CDC’s July 13 health advisory on the cyclosporiasis outbreak made no mention of Taylor Farms. Taylor Farms did not immediately respond to media requests for comment.
Taco Bell’s Response: Nationwide Lettuce Removal
Taco Bell’s response is documented, clear, and more aggressive than a company acting only from regulatory pressure would typically be.
Taco Bell issued a statement Thursday confirming it has voluntarily removed potentially impacted lettuce from its supply chain nationwide indefinitely and will replace it with alternative sources in selected states within the next day. “Based on ongoing conversations with public health officials, and out of an abundance of caution, Taco Bell has taken immediate action to voluntarily remove potentially impacted lettuce from a supplier in select states,” the company said, adding that the removal is nationwide.
Taco Bell also made a notable statement directed at other food service operators: “We encourage all relevant restaurants, retailers, and foodservice operators to do the same.” The company said: “While no official advisory has been issued, we believe public health is a shared responsibility among restaurants, their suppliers, and authorities, and we are proud to have consistently acted quickly and proactively to protect our guests.”
The nationwide scope of the removal, going beyond the five affected states, is more expansive than a purely reactive compliance response would require and appears to reflect the company’s concern about continued distribution of potentially affected product.
Michigan at the Center: 4,312 Cases and 102 Hospitalizations
The geographic concentration of the outbreak in Michigan makes the state-level data the most specific available indicator of its scale.
Michigan has been hit hardest in the outbreak, with 4,312 cases as of Thursday. The CDC’s national count of 1,645 confirmed cases often lags behind state-level counts, and Michigan’s own reporting demonstrates the gap. The state’s health department said that 102 people in Michigan have had to be hospitalized.
Michigan’s department of health has said it has interviewed more than 1,000 people as part of its investigation and had previously noted that lettuce or salad greens may be a potential source for the outbreak. The state cannot say with certainty that every illness is linked to the same source of exposure, but the concentrated, sharp increase in cases strongly suggests that the vast majority of these illnesses are associated with the same outbreak.
Taylor Farms’s Prior Food Safety Record
This is not the first time Taylor Farms has been the subject of a food safety investigation, and the pattern is relevant context for understanding why investigators focused on the company.
In 2013, the FDA traced a multistate cyclosporiasis outbreak connected to Olive Garden and Red Lobster restaurants in Iowa and Nebraska to salad mix from Taylor Farms de Mexico. In 2015, the company recalled a celery-and-onion mix tied to an E. coli outbreak in Costco chicken salads. In 2024, Taylor Farms slivered onions were identified as the likely source of the E. coli O157:H7 outbreak linked to McDonald’s Quarter Pounders that sickened more than a hundred people across fourteen states, dozens were hospitalized, and one person died. Following that outbreak, FDA inspectors documented poor handwashing and dirty equipment at the company’s Colorado processing plant.
Food safety attorney Bill Marler, who has been tracking the current outbreak, wrote on his blog: “The thread runs through all four… the FDA asked the chain where that lettuce came from, the answer, in Michigan, Ohio, West Virginia and Kentucky alike, was Taylor Farms.” He added: “A Cyclospora outbreak traced to Taylor Farms lettuce would not be the first time the parasite, or a supplier by that name, sat at the center of one.”
The company has not been formally named in an FDA or CDC advisory in the current outbreak as of publication, and no formal recall has been issued.
The CDC Surveillance Gap
A contextual factor worth documenting is the state of federal disease surveillance at the time this outbreak escalated.
Snopes previously reported that in 2025, the Trump administration cut the CDC’s surveillance of cyclospora. The significance of that cut in the context of the current outbreak has not been formally assessed by the CDC or the administration, but it is a documented background condition under which the outbreak’s early weeks unfolded without the same level of federal monitoring that would have historically been in place.
Michigan’s count of 4,312 cases already dwarfs the confirmed national CDC total of 1,645, demonstrating the gap between what states are measuring and what the federal surveillance system has captured in real time. The investigative work connecting the outbreak to a specific supplier has been driven substantially by state-level public health in Michigan rather than a centralized federal response.
What to Do If You’ve Eaten at Taco Bell Recently
The regional scope and the several-week infection window mean that some people who were exposed may not yet be symptomatic.
Cyclospora infections typically begin one week after exposure but can take up to two weeks to produce symptoms. Anyone who ate at a Taco Bell location in Michigan, Ohio, West Virginia, Kentucky, or Indiana in the past several weeks and experiences watery or explosive diarrhea, loss of appetite, fatigue, stomach cramping, nausea, or unexplained weight loss should contact their healthcare provider. Cyclosporiasis is treatable with a combination of the antibiotics trimethoprim and sulfamethoxazole (Bactrim, Septra). Untreated, the illness can recur or persist for months.
The FDA recommends that if you believe you have consumed potentially contaminated food, do not attempt to re-wash and consume it. Washing produce does not reliably remove Cyclospora. If you have experienced symptoms of cyclosporiasis following recent Taco Bell consumption in the identified states, report it to your state health department or call the CDC at 1-800-232-4636.
Latest Update: FDA Investigation Active, No Recall as of July 16
The Taylor Farms cyclospora outbreak 2026 investigation was active on Thursday July 16 with the FDA leading the probe. As of publication no formal recall has been issued, no official public advisory naming Taylor Farms has been released, and the total case count of nearly 7,000 remains under active investigation.

Broader Implications: Food Safety and the Leafy Greens Supply Chain
The Taylor Farms cyclospora outbreak 2026 is the latest in a decades-long pattern of contamination events involving fresh leafy greens at scale, and it raises structural questions about how the US food supply chain manages the risk of parasitic contamination.
Cyclospora typically contaminates produce through contaminated irrigation water or poor sanitation in agricultural settings. The parasite is resistant to chlorine treatment and survives standard washing and refrigeration. It cannot be killed by brief exposure to water, meaning the mitigation has to occur upstream in growing and processing. At the scale of a national produce supplier distributing to thousands of restaurant locations across multiple states, a contamination event in a single processing stream can propagate illness across an enormous geographic area before anyone identifies the source.
Taylor Farms is one of the largest fresh produce suppliers in the United States. The scale of its distribution network is what turns a localized contamination event into a multistate outbreak affecting thousands of people within weeks.

What Happens Next
The FDA investigation is active and expected to produce a formal public advisory if laboratory evidence confirms the Taylor Farms connection. A voluntary recall by Taylor Farms or a mandatory recall ordered by the FDA would follow. Michigan, Ohio, West Virginia, Kentucky, and Indiana health departments are all tracking cases. Taco Bell will replace its lettuce supply in affected states within 24 hours of the Thursday announcement and has removed the implicated supply nationwide. Anyone with symptoms should seek medical care and report to their state health department.
