Cyclospora Lettuce Outbreak Hits 20 States After Inspection Gap

Federal officials on Thursday tied a cyclospora outbreak in recalled iceberg lettuce to 20 states, with 11,458 confirmed illnesses and two deaths. Georgia, Tennessee and Texas were added to the roster. Both deaths were in Michigan, where state health officials said the patients had significant underlying health conditions.

The Food and Drug Administration says the lettuce came from Taylor Farms de Mexico, a processing plant in Guanajuato, and that recalled bags should no longer be on shelves. The same plant sat seven years between FDA visits, and it had already been in a cyclospora file in 2013.

Three More States Push the Lettuce Outbreak to 20

The agency’s Thursday update listed 11,458 illnesses reported from 20 states, 495 hospitalizations, and a last known onset date of August 15. A week earlier the same investigation stood at 10,930 illnesses in 17 states. The new states were already on the distribution list for the shredded product; they had not yet been counted as outbreak-linked illnesses.

The Centers for Disease Control and Prevention says illnesses in this cluster began on June 14. Most people got sick before Taylor Farms pulled central-Mexico iceberg on July 17. CDC genotyping found the parasites from patients in this outbreak are genetically related, which supports a shared source even though no leftover bag has produced a confirmed positive test.

The two deaths sit in both columns because CDC’s national file and the lettuce investigation report the same Michigan fatalities. CDC is also investigating at least six other cyclospora clusters whose food vehicles have not been named, so the 17,180 figure is larger than this recall.

The Same Guanajuato Plant Was Here in 2013

Taylor Farms de Mexico is not a new name in this parasite’s American record. In 2013, CDC, FDA, and health departments in Iowa and Nebraska tied 162 laboratory-confirmed cases to a prepackaged salad mix eaten at two related restaurant chains. The mix, which included iceberg and romaine, had been imported from Guanajuato.

The 2013 environmental assessment of the plant found the facility was recycling wash water for salad mix. Investigators could not pin the outbreak on a single step. A later FDA visit in 2019 found no violations, according to inspection records reviewed by CBS News. The next visit did not come until after this summer’s outbreak was already national news.

That 2013 season also included cilantro from Puebla, Mexico, which CDC later listed as the vehicle in outbreaks in 2013, 2014, and 2015. Basil from Morelos, Mexico, accounted for about 10 percent of the 2,408 domestically acquired lab-confirmed cases in 2019, the previous peak year since cyclosporiasis became nationally notifiable. This year’s lettuce cluster, on its own, is already several times that 2019 national total.

Seven Years Between FDA Visits to the Farm

CBS News, working from FDA inspection data, found the agency last walked into Taylor Farms de Mexico in 2019. The visit before that was the 2013 outbreak review. A routine inspection in 2011 completes the public record: three visits in 15 years, only one of which produced a report anyone can read.

Foreign food inspections as a class have been falling at the same time U.S. grocers and restaurants have been buying more Mexican produce. CBS found the FDA conducted just under 1,000 foreign food-safety inspections in 2025, a 29 percent drop from 2024 and, outside the COVID years, the lowest count since 2011. About 47,000 foreign manufacturers accounted for 90 percent of non-meat food shipments last year; the agency has inspected 4.5 percent of them since 2023.

INSPECTION MATH FROM THE RECORD

• 2025 foreign food inspections: Just under 1,000, according to CBS News analysis of FDA data.
• FSMA statutory target: 19,200 a year, a cap set after the 2011 food-safety law, which the agency has never approached.
• FDA’s own “needed” figure: About 4,700, from an internal analysis that was never sent to Congress as a revised target.
• Inspectors posted to foreign firms in 2024: 20, with the rest of the 432-inspector corps often pulled onto overseas trips from domestic ranks.

Emily Hilliard, a senior HHS press secretary, told CBS the agency uses a broader risk-based system than a single inspection tally and is trying to add staff at foreign posts. Companies, not inspectors, run the wash lines every morning. Dr. Don Schaffner, chair of food science at Rutgers University, made that point to CBS: day-to-day control sits with the firm. The outside check still failed to show up for seven years at a plant that had already been in a cyclospora investigation.

Shredded Lettuce Also Landed in Grocery Bags

Traceback first converged on shredded iceberg used at Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia. The chain said on July 17 it had finished removing the affected Taylor Farms lettuce from restaurants and from its national supply chain. That was the public face of the outbreak for about a week. It was not the whole map.

Taylor Farms initiated a recall the same day that also covered Marketside-brand Iceberg Salad in 12-ounce and 24-ounce bags and Shredded Lettuce in 8-ounce and 16-ounce bags, with best-if-used-by dates from July 18 through August 3. Those bags were sold at select Walmart stores in 15 states. The company has said no Taylor Farms-branded salad kits were in the recall and that the implicated farm represented less than 1 percent of the U.S. iceberg supply. It still suspended all iceberg lettuce sourcing from central Mexico and halted production at the Guanajuato plant.

WHERE THE RECALLED ICEBERG WENT

• Restaurants: Shredded lettuce at Taco Bell sites in at least five states, the first epidemiologic cluster.
• Retail bags: Marketside iceberg salad and shredded lettuce at Walmart stores in Alabama, Arkansas, Florida, Georgia, Indiana, Kansas, Kentucky, Louisiana, Missouri, Mississippi, Oklahoma, Tennessee, Texas, Virginia, and West Virginia.
• Foodservice: Confirmed shipments from June 29 through July 16 into 31 states, with possible further movement into D.C., Delaware, North Dakota, Puerto Rico, Rhode Island, South Dakota, Vermont, and Washington.
• Mexico: Customer records given to FDA show recalled product was also sold to consumers there.

Sysco, a major restaurant distributor, said it had already pulled Taylor Farms processed iceberg from Mexico and told customers to destroy it. FDA later widened the outbreak definition beyond people who ate at Taco Bell to anyone with a reported exposure to the processed iceberg, which is how the case count jumped from under 2,000 in late July to more than 6,000 by August 5, then past 11,000 this week.

Case Counts Keep Climbing After the Recall

The best-by dates have passed, and FDA says it remains confident the recalled iceberg is off the market. Counts are still rising because of how this parasite is found, not because new bags are landing in stores. CDC says it can take as long as six weeks to decide whether a sick person belongs in a cyclospora outbreak. Symptom onset in this cluster ran through August 15, so names will keep entering the file into September.

The average wait from swallowing the parasite to feeling sick is about one week, and the range runs from two days to two weeks or more, according to CDC clinical guidance. Watery diarrhea, loss of appetite, stomach cramps, bloating, nausea, and fatigue are the usual picture. Symptoms can fade and then return. The treatment of choice for cyclosporiasis is trimethoprim-sulfamethoxazole, one double-strength tablet twice a day for 7 to 10 days in otherwise healthy adults. People with sulfa allergies have few proven backups. Testing is not part of a routine stool exam, so a clinician has to ask for it.

1. June 14, 2026: First illness onset later counted in the lettuce outbreak, per CDC.
2. June 29 through July 16, 2026: Shredded iceberg from the Guanajuato plant is shipped into 31 confirmed states.
3. July 17, 2026: Taylor Farms removes central-Mexico iceberg from the U.S. market; Taco Bell says the affected lettuce is out of its restaurants.
4. July 19, 2026: FDA walks back a product sample that had been called positive, saying the result “should be considered a false positive.” Traceback is not withdrawn.
5. August 13, 2026: FDA says on-site inspection and sampling have begun at the plant, in coordination with Mexican officials, nearly a month after the link was made public.
6. August 27, 2026: Georgia, Tennessee, and Texas are added; the outbreak total reaches 11,458 lab-confirmed illnesses.

The July lab reversal did real damage to public understanding. A test that never should have been posted was read, in a lot of coverage and a lot of argument online, as if the lettuce had been cleared. Epidemiologists had not cleared it. They had a restaurant cluster, a single-supplier traceback, and, later, matching genotypes. They did not have a bag that tested positive, which is common with cyclospora because the parasite is hard to recover from food. The recall stayed in place. The case curve did not care about the press cycle.

National Cases Already Dwarf Last Summer

Separate from the lettuce file, CDC’s weekly surveillance table now shows 17,180 laboratory-confirmed domestic cases since May 1, plus 922 hospitalizations. The same May-through-August window in 2025 produced 1,180 confirmed cases. That is more than a fourteenfold jump in one season. Another 11,844 reports are still being sorted, and 1,805 more confirmed cases were acquired abroad.

Median age among the domestic cases is 46. Fifty-six percent are female. Median onset was July 7, which lines up with the heart of the lettuce shipping window. Michigan is the heaviest block on CDC’s map, in the 4,000 to 6,999 band, with Ohio in the 1,000 to 3,999 band. Delaware and Hawaii had reported zero confirmed domestic cases as of the August 24 data cut.

CDC’s own language is careful: the Taylor Farms iceberg outbreak “has contributed significantly” to this year’s rise, and other clusters are open. Even with that caveat, 11,458 linked illnesses would have been, by themselves, the largest documented U.S. cyclospora outbreak on the books. The 2019 national season, previously the high-water mark, closed at 2,408 domestically acquired lab-confirmed cases.

FDA inspections really are the first line of defense for mitigating outbreaks. If FDA isn’t routinely going out to food facilities, it’s just completely blind.

Meridith Seife, lead author of an HHS inspector general report on FDA inspections, speaking to CBS News

Seife was describing the domestic inspection program in that report, but the sentence fits the foreign gap that CBS documented. About a third of FDA foreign food inspections over the last decade found some kind of violation. Around 2 percent of visits led to enforcement. Those are the checks that did not happen, year after year, at the Guanajuato plant.

Shoppers Backed Away From Leafy Greens

The recalled bags are gone. The market damage is not. Reuters, cited in the CBS inspection report, said sales of prepackaged lettuce dropped nearly 20 percent in July while the outbreak was in the headlines. Growers and distributors have been living with a broader freeze: shoppers treated “lettuce” as the risk, not a short list of Marketside codes and a handful of Taco Bell tickets from June and July.

Taylor Farms says it spends $200 million a year on food-safety programs and independent audits. Company executives also sought a meeting with White House and FDA officials as the traceback landed, which Reuters and The New York Times described as a complaint about the inspection process. A month then passed before FDA announced it was on the ground in Mexico. Sampling there is still listed as ongoing.

The U.S. cyclosporiasis season on paper runs through August 31. Onset dates in the national file already reach August 19, and the six-week reporting lag means September will still be adding laboratory confirmations. FDA’s last line on the lettuce itself has not changed: the recalled iceberg is off the market, and the work left is in the fields and the wash plant that sent it.
