What caused the ongoing outbreak of cyclospora, the diarrhea-causing parasite currently spreading across the United States? Michigan officials have been saying for weeks that they believed the outbreak may be linked to bagged salad or salad kits. What we were waiting to learn was the specific brands and specific products in question
And late last week, it looked like we finally had the answer — but then things quickly got cloudy
On July 16, the Washington Post reported, citing anonymoustuce supplied to Taco Bell by Taylor Farms. A day later, Taylor Farms said it was withdrawing products from US stores and restaurants based on information from the FDA
But then on July 19, per NBC News, the FDA said that there had been a false positive for cyclospora when testing a sample of Taylor Farms iceberg lettuce; Taylor Farms said in its own statement that the FDA had “apologized” for the mix-up. The next day, the company and the federal government were stuck in a semantic argument: Per NOTUS, the FDA insisted it did not “officially apologize” to Taylor Farms but “explain[ed] factually the issues” with the false positive
So where does that leave us right now? Officials still believe that Taylor Farms iceberg lettuce was theducts driving the outbreak remains unclear, with almost every state now reporting at least one cyclospora case in 2026. And on Thursday afternoon, the FDA announced that it was tracking a second outbreak linked to other unspecific products, though details were otherwise scarce
Any outbreak of food-borne illness requires careful public communication. Officials need to tell people how to avoid contaminated food without scaring them away from eating fresh fruits and vegetables altogether
But instead, many Americans have been left wondering what, exactly, they’re supposed to do. As one frustrated Reddit user put it: “So is the damn lettuce bad or not????” (If you need some advice on what foods are safe and what foods to be cautious about, we have a story for you.)
It may sound like a funny question, but it’s a profoundly serious one. The problem isn’t just that people are confused about their lettuce. The Trump administration’s handling of the cyclospora outbreak — from its conflicting public messages to accusations of political favoritism — has left many Americans even more confused about whether they can trust anything they’re hearing from the government. That’s a dangerous place to be during any public health emergency
The cyclospora outbreak has become a communications nightmare
We are approaching 10,000 cyclosporiasis cases across the US this year: Michigan alone has recorded 7,664 as of this morning, Ohio has seen more than 1,200, and more than 40 states have now reported at least one case in 2026. The country usually sees a few hundred cases at most in a given year. Cyclosporiasis, the disease caused by the cyclospora parasite, leads to what public health experts describe as “watery” and “frequently explosive” diarrhea. While it isn’t typically life-threatening, it can cause serious complications: 160 people have been hospitalized in Michigan since the outbreak began.
Our political wellness landscape has shifted: new leaders, shady science, contradictory advice, broken trust, and overwhelming systems. How is anyone supposed to make sense of it all?

And so for those of us who very much hope to eat fresh produce but do notwant diarrhea, there’s a bit of urgency to figure out where the cyclospora is coming from. Food-borne illness investigations are already inherently difficult because of how globalized our food supply has become: Produce can travel all over the country and the world before it comes to your grocery shelf, and the process of government health workers interviewing the people who get sick and cross-checking to identify the shared foods that they might have in common is laborious.
Once investigators find aThat is where the Trump administration has tripped up this week
Trump — and Health Secretary Robert F. Kennedy Jr. in particular — came into office criticizing the public health establishment. They accused officials of misleading the public about the novel coronavirus and the vaccines developed to fight it, while failing to convey the nuances of the pandemic. But now, as they grapple with the incomplete picture of the cyclospora emergency, they are making many of the same mistakes
“They’re very similar problems, even if on the outside, they don’t look quite the same,” said Michael Mackert, director of the Center for Health Communication at the University of Texas at Austin. “The underlying commonality is very much that we are dealing with imperfect information all the time.”
In any outbreak, some uncertainty is to be expected. Investigators have struggled to identify thens that the likelye information they have gathered from sick patients and otheruch confusion
“The epidemiological evidence is so strong that the lack of a positive test is almost meaningless,” said Francisco Diez-Gonzalez, director of the Center for Food Safety at the University of Georgia
But the mistake that the Trump administration made was in sharing preliminary results and then having to issue a seemingly contradictory statement shortly afterward
“FDA should have waited for confirmation of the presumptive results before going public,” Diez-Gonzalez said
The larger stakes of the Trump administration’s poor communication
Investigations like these are hard enough — but when you add in the public health funding cuts of the past 18 months and the casual and widespread corruption characteristic of the Trump administration, trust in the government’s public health apparatus has sunk even lower
It’s created just the conditions for conspiracies to bloom. “Unfortunately our FDA is compromised,” wrote one top commenter on Reddit. “I would not trust what comes out of it during this administration.”
Several news outlets and influential social media accounts noted that Taylor Farms had donated $1 million to Trump’s MAGA super PAC and, in the middle of the controversy, received a private White House meeting. According to the New York Times, Taylor Farm officials used that meeting to dispute the findings that their products were responsible for the outbreak — and shortly thereafter, the FDA made its “false positive” announcement
The administration insists that their decision-making is being guided by science, but even the appearance of impropriety has become a common theme in the press coverage. The broader uncertainty and distrust may help to explain why it’s not only Taco Bell and Taylor Farms taking a hit right now: According to Market Watch, Chipotle and the fast-casual salad chain Chopt have also seen a decline in traffic in recent weeks
Public health requires public confidence. Perceived influence from special interests is a problem, even if the interactions didn’t alter the FDA or CDC’s actions
Kennedy, who helms our government’s health department, should understand this well: His Make America Healthy Again movement made restoring public trust a central part of its message while accusing the existing public health establishment as being in league with special interests
The cyclospora outbreak has revealed how difficult that is to do in practice
In trying to communicate nuanced information during an active outbreak — while consulting interested parties like Taylor Farms itself — the administration has instead fueled doubts about the credibility of its messaging
Even before cyclospora turned eating salad into a leap of faith, Trump had a poor track record: His administration has slashed CDC staff, brought on vaccine skeptics to set vaccine policy, and clashed with the scientific establishment on a number of high-profile issues, like the time Trump held a televised press conference to argue a disproven theory that Tylenol can cause autism
“Unfortunately, this is another example of a missed opportunity to establish credible and trusted communications to prepare the public to understand the real risks from the pathogen and confidence in the food safety and information from the FDA,” Scott Ratzan, editor-in-chief of the Journal of Health Communication: International Perspectives, told me. “Faith in our institutions continues to erode. We could do better.”
We are lucky cyclospora is not a deadly disease. Next time, the stakes for these miscues could be much higher
