On Sunday and Monday I posted about this outbreak. One post showed that FDA already answered the argument Taylor Farms is making, in a 2020 warning letter to another salad company. The other walked through every public version of the theory that the parasite came out of Michigan and Ohio water, and the papers offered to support it.
Monday, the International Fresh Produce Association posted the final version of its consumer FAQ — stamped September 14 at 10:00 a.m., with a note that the page will not be updated again and that readers should go to the federal sites. It is now the association’s permanent record of the 2026 season. Some of it deserves credit. One part of it should still be withdrawn. And on the central question my first post was about, the association and one of its largest members are now on opposite sides, with the association plainly in the right.
On the question Taylor Farms is fighting, IFPA answers it straight
Asked whether a specific food was identified, the page says yes. Asked whether the recalled product tested positive, it says there were no confirmed positive product results at any point in the investigation, that the recall and the findings rested on epidemiologic evidence and traceback rather than a positive laboratory test, that produce testing for this parasite has real and documented limitations including low sensitivity at low contamination levels, that implicated product is usually gone before testing is possible — and that the absence of a positive sample did not mean the epidemiological and traceback findings were wrong.
Compare that with the sentence still posted on the Taylor Farms hub: epidemiology can point to a potential source but cannot confirm that a specific product caused illness, and that confirmation requires a positive lab test. One of those two statements matches what FDA told Fresh Express in October 2020 — that it is not uncommon to see many negatives even when contamination has occurred. It is not the one on the company’s website.
The narrowing on water is real, and it belongs in print
In the version stamped September 4, the one I quoted on Sunday, the sewage-overflow material sat under a heading asking what else could be a source of infection. In the final version it has moved into a section describing what IFPA raised during the investigation, written in the past tense, and it is fenced: the page says those concerns were raised in connection with the smaller, still-unconfirmed clusters, not as an alternative explanation for the confirmed Taylor Farms de Mexico finding, which FDA tied to imported product from central Mexico.
That is a narrowing and I said in my last post that it belonged in print. It still does. The association has conceded the recall cluster and scoped water to the cases nobody can explain — roughly six thousand seven hundred laboratory-confirmed illnesses this season, on the agencies’ own figures, sitting outside the outbreak count with no source publicly identified. Those cases are real. Adding water questions to a hypothesis-generating questionnaire costs almost nothing and might answer something.
One claim survived the edit and should not have
The page still says there was documented, significant rainfall and combined sewer overflow activity in parts of the affected region in mid-June, and that the timing is worth continued attention. The page’s own biology answers it. IFPA states that oocysts need seven to fifteen days in a warm, moist environment before they can infect anyone, and that symptoms begin on average about a week after exposure. CDC puts the first outbreak-linked illness onset at June 14. Work backward through a week of incubation and one to two weeks of sporulation and the contamination event lands in late May. A mid-June overflow is downstream of the illnesses it is offered to explain.
Scoping that claim to the unexplained clusters does not repair it. The timing argument fails on IFPA’s own numbers no matter which cases it is pointed at. On a page that will never be updated again, it should come out.
The word doing the quiet work is subcluster
Throughout the final version, the 12,883 illnesses are a subcluster of a broader outbreak. Neither agency uses that word. CDC’s final update calls it a multistate outbreak and states in its own voice that epidemiologic and traceback data showed the Taylor Farms de Mexico iceberg lettuce was contaminated and made people sick. FDA’s advisory says the same and keeps its investigation open. Nothing is inaccurate about the word subcluster — there were other clusters — but it shrinks the largest confirmed produce outbreak in the history of this parasite into a portion of something unexplained, and vocabulary does argument work that footnotes cannot.
Two sentences on that page cut against me, and I will say so
The page says findings in a Cyclospora investigation are strongest when supported by multiple complementary lines of evidence rather than resting on any single source in isolation. And it says patient interviews and purchase records are an important piece of the puzzle, “but not a substitute for the physical and laboratory evidence” that is harder to come by with this parasite. A defense lawyer will put that second sentence next to everything else I have quoted and argue the association agrees with Taylor Farms.
The answer is on the same page. There were multiple lines here: epidemiologic interviews across twenty-one states, a traceback that converged on a single supplier, and CDC genotyping showing the parasites from sick people are genetically related. IFPA read all of that and still answered yes when asked whether a food had been identified. Wanting more evidence is not the same as saying the evidence you have proves nothing. Taylor Farms is making the second argument. Its association is not.
One error worth fixing even on a closed page
The page tells consumers that all water used for crop irrigation must meet cleanliness standards set by FDA. Three answers later it explains, correctly, that since the 2024 update to the Produce Safety Rule pre-harvest agricultural water is no longer tested against numerical criteria at all — farms perform a documented annual assessment instead, and only post-harvest water carries a testable microbial standard. Both statements cannot be true. The first is the one a worried consumer will remember, and it is the wrong one.
There is also a mismatch on the July 18 sample. IFPA describes it as routine random sampling unrelated to the recalled product. FDA’s own July 19 update describes it as a sample of lettuce supplied by Taylor Farms de Mexico. Both can be true if the lot was never part of the recall, but the supplier’s name is in FDA’s sentence and not in IFPA’s.
What the page gets right, and what I will back
Three things on that page are more useful than anything the implicated company has published all summer.
First, the undercount, stated by the industry itself: this parasite does not appear on the standard parasite panel, a physician has to ask for it specifically, and doctors are advised to test three separate stool samples on different days before calling a negative real. Every count this season is a floor.
Second, the admission that there is no FDA guidance and no validated, Cyclospora-specific protocol telling growers how to prevent contamination. IFPA calls it a real gap rather than an oversight, and points growers to university extension material for lack of anything federal. That is a striking thing for the largest produce association in the country to have to write, and it is an argument for a rule rather than against one.
Third, the FSMA 204 answer. IFPA says it cannot quantify what the delay cost this investigation but that the underlying gap is real, that traceback here ran on interviews, purchase records and manual work, and that it continues to advocate for full implementation. Good. I will take that sentence to Congress the next time somebody proposes to push the compliance date again.
The association has also proposed an FDA-led public-private task force to do a root cause analysis now that the investigation has closed. I support that, on three conditions: the findings get published, the sampling data behind them gets released, and somebody in the room does not work for the industry being examined. FDA has said it plans a root cause analysis of its own. Those are compatible.
The ask: nine things IFPA could put its name on before next May
On Saturday I listed ten things the FDA should do before the next season. This is the industry half of that list. None of it requires anyone to concede a lawsuit, and most of it does not require a statute. Several items IFPA has already half-endorsed, which is the point — finish the sentence.
1. Oppose any further delay of FSMA 204 and say so to Congress. The compliance date is July 20, 2028, moved there from January 2026, and last November’s appropriations law directed FDA not to enforce before that date. IFPA says it cannot quantify what the delay cost this investigation but that the gap is real. Then defend the date publicly and ask Congress to lift the spending prohibition that keeps FDA from building the receiving system Section 204 ordered in 2011.
2. Co-fund a detection method a grower can actually run. FDA has a validated laboratory method for finished produce. There is nothing comparable for irrigation water, sediment or soil at commercial scale and speed, and IFPA’s own page concedes there is no validated prevention protocol for this parasite at all. Put industry money behind method development, insist the limit of detection be published, and stop asking members to manage a hazard they cannot measure.
3. Back restoration of the defunded federal Cyclospora research. Two federal research projects went unfunded in the FY2026 agriculture bill and a third is being moved away from the scientists running it. An association that wants better tools should be saying which questions its members cannot answer without that work.
4. Support making Cyclospora mandatory in FoodNet again. Reporting for this parasite became optional on July 1, 2025, after twenty-eight years. We went into the worst season on record without the yardstick for normal. Restoring it costs the industry nothing and gives every member a defensible baseline.
5. Fund state laboratory capacity for genotyping. CDC’s genotyping was the first tool this summer that did not depend on somebody remembering a June salad, and it is the tool most likely to separate one company’s product from everyone else’s in the next outbreak. Industry has more to gain from that separation than anybody.
6. Adopt a members’ disclosure standard for testing claims. Any member that publicly cites its own testing numbers publishes the composition behind them: matrix, method, sample weight, dates, lots and results. FDA’s 2013 assessment of Taylor Farms de Mexico did exactly that — it printed the table, and the table showed that of 793 samples, 42 were finished product. An association can write that standard into its own code of practice tomorrow.
7. Write a worker sanitation standard built for a human-only parasite. That same 2013 assessment found field handwashing stations whose valve handles created a cross-contamination route and recommended that employees with diarrhea be encouraged to submit stool samples. Thirteen years later there is no standard requiring hands-free handwashing at field sanitary units, documented pump-out siting and service records, or access to testing and paid sick leave for symptomatic harvest workers. Humans are the only host. Everything else is downstream of that.
8. Make a documented growing-region assessment a condition of supply for imported leafy greens. For regions with a documented history of this parasite, ask members to require — under their existing foreign supplier verification obligations — a written assessment of the region’s sanitation infrastructure and water sources, and publish the audit standard so buyers and growers are working from the same document.
9. Fund wastewater surveillance for this parasite, including in growing regions. This one is IFPA’s idea and I am adopting it. The association asked CDC to consider routine wastewater surveillance to understand where the parasite is present. It is a sound proposal for an organism that exists only in human waste, and it would be more useful still in the valleys that grow American winter produce than in Lake Erie.
Add the condition I put on the task force: FDA publishes the root cause findings and the sampling results either way, and someone in the room does not work for the industry being examined. A published negative tells every farm in that valley the contamination was not where investigators looked. FDA’s letter to industry asks members to apply rules already on the books and promises to fold lessons into an action plan first published in 2021. Nine specific commitments from the largest produce association in the country would be worth more than that letter.
The association is carrying weight it should put down
IFPA’s page and Taylor Farms’ page now sit on opposite sides of the same question. One says the finding rested on epidemiology and traceback and that the absence of a positive sample did not make it wrong. The other says only a positive sample could have confirmed anything. FDA said the first thing in an enforcement letter six years ago. CDC said it in its final update this month. The association got it right.
What remains is the water paragraph, kept alive on a page that will never be edited again, on timing its own biology contradicts. Take it down and take up the nine. Nineteen thousand five hundred and ninety-five Americans were laboratory-confirmed with this parasite between May and September, and roughly six thousand seven hundred of them still have nothing written next to their names. The season starts again in May. There is time.
