Episode Overview

This episode unpacks the ongoing U.S. outbreak of Cyclospora, a foodborne parasitic illness causing an epidemic of “explosive, watery diarrhea,” particularly in the Midwest. Hosts Sean Rameswaram and Dylan Scott break down the nature of the bug, why it’s spreading, who’s affected, and what’s being done in response. Later, Wall Street Journal health reporter Liz Asley White joins to discuss how the White House’s dietary habits inadvertently make them immune to the crisis, and Dr. Sean O’Meara explains potential gut-health benefits of fermented foods.

Key Discussion Points & Insights

1. What Is Cyclospora?

[00:12]

• Dylan Scott describes Cyclospora as a “nasty parasite”:

  “…if a human being consumes it…‘explosive, watery diarrhea’...huge gastrointestinal issues. If you get sick with this, it can last for up to a month.” (00:12)

• Not fatal, not transmitted person-to-person, primarily a foodborne illness.

2. Scope and Epicenter of the Outbreak

[04:05]

• Michigan is the epicenter: over 4,300 confirmed cases, a sharp rise from 1,500 the previous week, likely an undercount.
• Prior outbreaks rarely affected more than a few hundred people; this is unprecedented.

  “We may eventually reach, like, 10,000 cases of this parasite before it's all said and done.” – Dylan Scott (04:05)

3. Why Is This Happening?

[05:21]

• Causes:
  1. Globalized food system – produce (esp. leafy greens) is shipped worldwide, allowing for greater risk of contamination.
  2. Climate change – warming temperatures make new regions hospitable for the parasite.

  “It’s more of a byproduct of the way our food supply has changed… Climate change is probably playing a role too…” – Dylan Scott (05:21)

• Typical transmission: contaminated irrigation water in warm climates → shipped to U.S. → consumed in salads.

4. Source of the Outbreak

[07:42]

• Ongoing investigation:
  • Iceberg lettuce supplied to Taco Bell by Taylor Farms is suspected in the Midwest outbreak.
  • Not definitely confirmed; could be multiple sources or outbreaks.

  “…CDC and FDA officials were zeroing in specifically on iceberg lettuce that had been supplied to Taco Bell by the company Taylor Farms.” – Dylan Scott (07:42)

• Taco Bell’s recurring reputation in foodborne illness events is noted with some humor.

5. Prevention and Food Safety for Individuals

[09:39]

• Avoid raw leafy greens; cooking vegetables kills the parasite.
• Emphasis on thorough washing and food hygiene.

  “If you do take careful steps to really thoroughly wash your food…there's a really good chance that you can get rid of it.” – Dylan Scott (09:39)

6. Government Response and Failures

[10:24]

• State health departments are leading, unusual for a multi-state outbreak:
  • CDC data lags due to federal reporting cuts, traced back to policy shifts in the Trump administration.
  • In 2025, CDC stopped mandatory state reporting for Cyclospora.

  “…federal government stopped asking states to report cyclospora cases. So that may explain why there's been this lag…” – Dylan Scott (11:17)

• Cuts and reduced public health capacity slowed the official response:

  “…if we had had a more robust CDC, you know, it's possible we would have identified the problem earlier, been able to mount a response faster…” – Dylan Scott (12:36)

White House & Fermented Foods: A Surprising Angle

7. The White House Diet Trend

[17:27]

• Liz Asley White reveals that top White House officials are on a “carnivore” diet—meat, eggs, yogurt, and notably, fermented vegetables like sauerkraut and kimchi.

  “Kennedy calls it the carnivore diet…a lot of yogurt, a lot of kimchi or sauerkraut, a lot of steak, a lot of eggs.” – Liz Asley White (18:15)

• No fresh lettuce or leafy greens—so, unintentionally protected from the Cyclospora outbreak.

8. Origins and Science Behind This Diet

[20:23]

• New national dietary guidelines recommend more fermented foods (and controversially, more red meat).
• Some clinical evidence supports fermented foods for gut health, but not specifically for weight loss or explosive diarrhea prevention.

  “Researchers have generally agreed that sauerkraut and other fermented foods can help with digestion and inflammation.” – Liz Asley White (21:17)

• The link to red meat sparks controversy among dietitians.

9. White House Influencers: Dr. Sean O’Meara

[22:55]

• Dr. Sean O’Meara, a retired Army colonel and MD, influenced key officials with anecdotal and clinical wellness claims about fermented foods.

  “There are a number of studies that show the connection…with a lower incident of chronic disease.” – Dr. Sean O’Meara (23:25)

• He recommends fermented foods as a “garnish” rather than the main fare.
• Warns pickled foods are different and may carry cancer risks.

10. Do Fermented Foods Help with Cyclospora?

[25:43]

• Dr. O’Meara:

  “Yes, yes, I really do think so. Because...if you have living within your stomach a healthier microbiome, they will overcome that particular introduction.”

• Liz Asley White: “I have not seen any studies on whether fermented foods help with explosive diarrhea…” (27:06)
• Conclusion: Fermented foods are gut-healthy in general, but there’s no direct evidence for Cyclospora protection.

Notable Quotes & Memorable Moments

• “Do you want to have to deal with a month of explosive diarrhea?”
  – Dylan Scott (02:38). (A recurring blunt rhetorical cue throughout the episode.)
• “My doctor confirmed that I consume enough Miller highlife and hint of lime tortilla chips to create a digestive environment untenable for the explosive diarrhea parasite.”
  – Sean Rameswaram’s humor (03:31)
• “They just got unlucky…could have ended up at a grocery store…turned out in this case to end up at Taco Bell.”
  – Dylan Scott (09:00)
• “So he's gonna live forever.”
  – Sean Rameswaram joking about the president’s penchant for pizza, fries, and Diet Coke (18:57)
• “If we had had a more robust CDC...we would have identified the problem earlier…minimized the number of people who get sick…”
  – Dylan Scott (12:36)
• “What you want is an African safari living with you…zebra, tigers, lions, chimpanzees…creating a healthy environment.”
  – Dr. Sean O’Meara humorously on the ideal microbiome (26:09)

Transcript

[Sean Ramesh Firm]

Today explained here with Dylan Scott from Vox to ask what the bug is. Cyclospora.

[Dylan Scott]

So cyclospora is a parasite, and it is a particularly nasty parasite because if a human being consumes it, then that person can experience. And this, I want to be clear, is the terminology that is used by public health authorities. Explosive, watery diarrhea, explosive diarrhea, frequent diarrhea, huge gastrointestinal issues. If you get sick with this, it can last for up to a month. It's just a really unpleasant foodborne illness that is wreaking havoc across the United States and particularly in the Midwest right now.

[Sean Ramesh Firm]

And so we have to talk about it on the show today. Sorry. Support for this show today comes from Anthropic, the team behind Claude. Claude is the AI for minds that don't stop at good enough.

[Sean Ramesh Firm]

This is Today Explained. Now, you underlined the thing that feels quite normal about a stomach bug, but I want to underline something that feels abnormal here, which is a month.

[Dylan Scott]

I know I've talked to some people or had people in my life ask me, like, how big of a deal is this really? Like, you know, do I, Do I really need to be going out of my way to be safe about this? And my answer is, do you want to have to deal with a month of explosive diarrhea? And personally, my answer to that would be no. And so I have been taking precautions as somebody who lives not too far from the epicenter of this outbreak. But, yeah, this is. It's a nasty thing. Like, the good news about this parasite is it doesn't kill people. Like, it's not fatal. It doesn't transmit between person to person. It's nothing like that that we have to worry about. But it does cause these really unpleasant gastrointestinal symptoms, and that's what public health authorities, especially in Michigan, are contending with right now.

[Sean Ramesh Firm]

If it doesn't kill people, we can laugh about it. And many people are laughing about it. My doctor confirmed that I consume enough Miller highlife and hint of lime tortilla chips to create a digestive environment untenable for the explosive diarrhea parasite.

[Dylan Scott]

If I got the explosive diarrhea parasite, I probably wouldn't even just one diarrheal parasite away from my goal weight.

[Sean Ramesh Firm]

But you mentioned the epicenter, Dylan. Where is it and where else is it?

[Dylan Scott]

So the big outbreak right now is in Michigan. The last update that I saw was there are more than 4,300 cases of cyclosporiasis in Michigan right now. That is up from just about 1500 late last week. And so, like, that's a really rapid growth in cases. And the doctors that I have talked to who are based in Michigan, have said, like, that's just the ones we've confirmed with a test, like, the actual number of cases. And so the actual number of people who are dealing with this really unpleasant diarrhea right now is probably even higher than that. And, like, we've seen outbreaks in the past, you know, maybe a couple hundred people who got sick, like, back, you know, 2018, 22,005, but, like, never anything like the thousands of cases that we're seeing right now in Michigan. And the doctors I've talked to there have said, like, it's probably gonna keep going, and we may eventually reach, like, 10,000 cases of this parasite before it's all said and done.

[Liz Asley White]

Ugh.

[Sean Ramesh Firm]

What did the United States do to deserve this terrible parasite? Is it the war we started for no reason or, like, only letting white people in for the World Cup?

[Dylan Scott]

So I have to say, like, this isn't anybody's fault. Oh, like this. Like I said before, this is something that we have dealt with in the past. It's getting a lot more attention now, I think, because of how big the outbreak has gotten. But, like, we've dealt with cyclospora before, and if you want to blame anything, there's probably two Things to blame. One would be we now have this really globalized food distribution system where, like, we're getting leafy greens grown all over the world and shipped to plants in the United States and being, you know, packaged into these bag salad kits that I personally love to buy for lunch and sold all over. And so there's this long chain where produce can potentially get infected with Cyclospora. Like the kind of classic example would be, you know, there's a field in some tropical region of the world where they're growing lettuce. It gets irrigated with water that has been infected by this parasite, and then it's all these weeks later, after it's been harvested and packaged into something and put on your grocery shelves and you've eaten it, that then finally you get sick. And so it's more of a kind of byproduct of the way that our food supply has changed as well as potentially. And I feel like this is an evergreen topic with any kind of disease like this. Climate change is probably playing a role too. Like, this parasite tends to thrive or is naturally found in, like, tropical or subtropical regions. But we have started to notice it appearing domestic domestically as well. And that's because, like, as the planet starts to get warmer, there are going to be more places with the kind of climate where this parasite could thrive. And therefore, you know, it may not be an accident that we're dealing with the worst outbreak ever right now. And it may be a preview of things to come. This might be just something that we have to deal with from time to time because of these food systems that we've set up and because of the. What's happening with the planet.

[Sean Ramesh Firm]

Do we know where this all started for the United States, Dylan? Is there a patient zero or a, I don't know, a Taco Bell zero or like a, you know, a leafy green farm zero, whatever it might be.

[Dylan Scott]

So it looks like we're getting closer to figuring that out. For the past week, health officials in Michigan had said, we think this is linked to lettuce or bagged salad. But they hadn't gotten much more specific than that. And then on Thursday evening, the Washington Post reported that CDC and FDA officials were zeroing in specifically on iceberg lettuce that had been supplied to Taco Bell by the company, Taylor Farms. They thought that that potentially that specific product and that specific brand being sold at that particular restaurant might be the source of the ongoing diarrhea outbreak. Now, they haven't confirmed this for sure. It is possible, like there's cyclosp cases all over the country this summer. It could be that we're dealing with a couple of different outbreaks, but in terms of the big crisis in Michigan and Ohio and a couple of those neighboring states, it appears, according to this preliminary reporting, that if you ate at Taco Bell and got a dish with iceberg lettuce, that might be why you ended up getting sick.

[Sean Ramesh Firm]

Why is Taco Bell always somewhere in these situations? What the heck's going on at Taco Bell?

[Dylan Scott]

You might to deal with diarrhea because you're eating Taco Bell for other reasons then we don't have to get into that right now. But it appears that in this case they just got unlucky. They were sourcing this particular ingredient from this particular company and got a batch that was contaminated with Cyclospora. And you know, it could have ended up at a grocery store or at a different restaurant, but it turned out in this case to end up at Taco Bell. And so, yeah, as best as we know sitting here today, that seems to be the most likely source for this outbre.

[Sean Ramesh Firm]

So what do you do if you're like missing Taco Bell this weekend? Maybe just like eat a tuna sandwich or something.

[Dylan Scott]

There's lots of things like, you know, obviously anything that's not a fruit or vegetable that you could eat, heat is a really good way to kill this parasite. So like, if you want to eat vegetables, maybe you could grill them, stuff like that. And then, you know, I do think in general this whole episode is a really good reminder about how important food hygiene is because like, if you do take careful steps to like really thoroughly wash your food, even the like green leafy vegetables that we worry might be contaminated with this parasite, like there's a really good chance that you can get rid of it and eat that stuff that is obviously really good for your body's health in general and not have to worry about getting debilitating diarrhea.

[Sean Ramesh Firm]

That's what we can do. What about the old government, Dylan? What are they doing and what could they be doing? In a moment where thousands upon thousands of Americans are getting a violent stomach

[Dylan Scott]

bug, I will say that like the state health departments are definitely taking the lead on this outbreak, which is unusual usually, especially when you're dealing with a multi state outbreak, as we seem to be at this point, you would expect the CDC and the federal government to be taking the lead. But the CDC's case counts have lagged pretty far behind what the states have been reporting at this Point. I was told by a hospital epidemiologist in Michigan that last year the federal government stopped asking states to report cyclospora cases. So that may explain why there's been this lag in federal data.

[Ad Read Announcer]

What?

[Dylan Scott]

Yeah. And so it's like, again, I'd want to emphasize that, like, this could have happened no matter what. You know, food surveillance in the United States has been lacking for a long time, well before, you know, the cuts we've seen to the federal workforce under the Trump administration here in the last couple years. But at the same time, now that we are dealing with a live, active emergency, it certainly doesn't help to have a CDC and federal health authorities, who seem to be a step behind, doesn't help that the fact that there's, you know, fewer workers, fewer resources that the CDC and federal government can spend responding to this outbreak. So, you know, the truth is somewhere here and there in the middle where it's like, you know, they're doing what they can, states are taking the lead. You know, this probably would have happened no matter what because this is just a reality of the food distribution system that we've set up. But at the same time, we are, you know, we've got a federal government that does have one hand tied behind its back when it comes to responding to public health emergencies. And that's probably not helping us, you know, get this over with faster either.

[Sean Ramesh Firm]

And just to be sure here, you said earlier that no one is really to blame here. But with cuts to monitoring of this particular parasite, can you blame people for rushing to judge this, this particular administration?

[Dylan Scott]

No, no, I get. And like, yeah, that's the sort of, like, unfortun, worst error that we've seen a lot in how the Trump administration has been changing public health policy, you know, stopping reporting requirements when there doesn't seem to be a need to do so, disbanding task force that are dedicated to pandemic preparedness, like, you know, if we had had a more robust cdc, you know, it's possible we would have identified the problem earlier, been able to mount a response faster, moving more quickly, and all of those things, you know, could have ultimately minimized the number of people who get sick, the number of who end up in the hospital, and that would have been a good thing.

[Sean Ramesh Firm]

Dylan Scott, thank you so much for joining us. To help us understand this bug and when we get back on today explained, we're going to talk about how a bunch of powerful people in the White House don't need to worry about catching it because they stopped eating fresh vegetables before this bug necessitated it.

[Liz Asley White]

TODAY explained I'm Liz Asley White and I'm a health reporter for the Wall Street Journal.

[Sean Ramesh Firm]

And Liz, as you know, the nation is terrified of a gut parasite at the moment. People are wondering what to eat instead of their leafy greens. And you recently reported that the White House of all place might have an idea. What is it?

[Liz Asley White]

Sauerkraut or kimchi or some other fermented vegetable?

[Sean Ramesh Firm]

What is going on in that White House? What does it smell like?

[Liz Asley White]

I can't say that I personally have been smelling the White House, but I will say that Health Secretary Robert F. Kennedy Jr.

[Dylan Scott]

I went to dinner at the Ned last night and I brought my sauerkraut.

[Liz Asley White]

Commerce Secretary Howard Lutnick, Transportation Secretary Sean Duffy, and Vice President J.D. vance are all on this eat a lot of steak and sauerkraut diet and they claim a lot of health benefits. And actually, you know, fermented foods are recommended by a lot of doctors and scientists and not just the White House.

[Sean Ramesh Firm]

Is there like a name for this diet, like a la Paleo or whatever

[Liz Asley White]

else Kennedy calls it, the carnivore diet. I think people mean different things when they say that, but for him it includes a lot of yogurt, a lot of kimchi or sauerkraut, a lot of steak, a lot of eggs.

[Sean Ramesh Firm]

None of these things, I believe, are known to carry the parasite we've been discussing on this show. Exactly.

[Liz Asley White]

No lettuce.

[Sean Ramesh Firm]

How widespread is this in the White House? Does it go up all the way to the top to the president? Is he partaking in the carnivore diet?

[Liz Asley White]

I mean, given what we have seen of his recent public dieting, I don't think so. At the Knicks game, he was eating pizza and French fries and, you know, he still has his Diet Coke button on his desk where he just pushes it and a Diet Coke comes.

[Sean Ramesh Firm]

So he's gonna live forever.

[Liz Asley White]

Yeah. Kennedy once said on a podcast about

[Dylan Scott]

him, I Don't know how he's alive.

[Liz Asley White]

So, anyway, Kennedy now travels with sauerkraut. Like, his wife has said that he has asked her to carry it in her purse for him. And she has said, I actually cannot, which is an amazing phrase.

[Sean Ramesh Firm]

One of the many humiliations of being married to Robert F. Kennedy, Jr.

[Liz Asley White]

It seems they all think their skin is glowing, too. And people online have commented that JD Vance is looking good, so.

[Sean Ramesh Firm]

And are we sure that. I mean, I have to ask journalistically, but are we sure it's not wegovy?

[Liz Asley White]

We don't have any public knowledge of that, but we do know that he is eating eggs, sauerkraut, pickles, blackberries, and raspberries for lunch pretty often.

[Sean Ramesh Firm]

Wow.

[Liz Asley White]

And beef and lamb with sauerkraut for dinner. And then when he's on Air Force Two, he snacks on beef jerky and maybe eats a hamburger with cheese, no bun, and a side of fermented vegetables. So still no lettuce, but I think the raspberries could have the diarrhea parasite.

[Sean Ramesh Firm]

Now that you're mentioning the full spectrum of, like, J.D. vance's diet, it's kind of reminding me of their new food pyramid. Is this part of that? Does it fit in?

[Liz Asley White]

Yeah. Earlier this year, Kennedy and the other health officials like to say they flipped the food pyramid.

[Dylan Scott]

As Secretary of Health and Human Services, my message is clear. Eat real food.

[Liz Asley White]

And they recommended a lot more fruits and vegetables, red meat, which was controversial, and whole grains and whole milk, that kind of thing. They also, for the first time in the nation's dietary guidelines, recommended fermented foods, which, you know, was something that was actually agreed upon by a lot of people, and they thought that was a good part of this. Even if they had qualms about the red meat recommendations, because those can introduce more cardiac risk and, you know, risk of bad cholesterol.

[Sean Ramesh Firm]

Does the science back this up, or is this some kind of question that ferments can make your skin healthier and help you lose weight? Is it correlation or causation?

[Liz Asley White]

So I don't think there are a lot of good studies that show exactly that sauerkraut can help you lose weight. But there have been a number of studies that have shown health benefits. Researchers have generally agreed that sauerkraut and other fermented foods can help with digestion and inflammation. There was a 2025 study from UC Davis that suggested fermented cabbage could protect your gut and protect against illness. Basically, they found that the intestinal cells do better with sauerkraut. They help maintain the integrity of those intestinal cells. And in general, that has a lot of other good health effects. Mainstream scientists, dietitians are pro fermented veggies. This is not something that is hotly debated. Most people in the scientific community are realizing there's a lot of good, fresh science out there about how important your gut really is in your overall health. And the part of the diet that is a little more controversial is the focus on red meat. And obviously that comes with some cardiac risk and some cholesterol risk. And that is why when the new dietary guidelines came out and recommended more of that for Americans, that part in particular made some dietitians a little upset.

[Sean Ramesh Firm]

Who got Robert F. Kennedy, Jr. Into this, or is this part of his broader fitness regimen?

[Liz Asley White]

He had a friend who pointed him to this. Dr. Sean O' Meara.

[Dr. Sean O'Meara]

Am Sean O', Mara, Maryland, J.D. i'm a retired army colonel. And by the way, you know, I don't know why I get mostly exclusive conservatives, but they tend to be. But dude, I'm super excited to be chatting with you.

[Sean Ramesh Firm]

So what is your connection, Dr. Sean, to people in the White House eating more fermented foods? Can you tell us that?

[Dr. Sean O'Meara]

That I take care of a lot of prominent people. And so there was a one of my clients I work with had a 93 year old mother. She was not talking, hadn't been out of her bed in three years and they got her off processed foods and carbohydrates and they got her eating meat, seafood and fermented foods, just those things. And within three weeks, less than three weeks, she started talking and she got up out of the bed and started using her walker. So that was raised, got to a cabinet member, you know, who expressed interest in working with me and getting my physician care and helping them become more optimally healthy. So it is anecdotal, but there are a number of studies that show the connection between fermented living probiotic foods that haven't been pasteurized. Have these, these living species of bacteria and yeast and fungi and a whole host of different life forms living in them, benefiting people and associated with a lower incident of chronic disease. So this is not something that's novel, it's not something that's fad. It's been around in traditional people for thousands of years.

[Sean Ramesh Firm]

Are there risks to eating too much fermented foods?

[Dr. Sean O'Meara]

Well, it has not been studied, but I will say this. It comes up occasionally in some studies where people eat too many pickled foods, which is a different thing than fermented Foods, pickled foods are not probiotic. They're not living. They're not preserved through bacteria. They're preserved through acetic acid, usually vinegar. That pickling is a chemical process rather than a bacterial biological one. And then as a consequence of all that pickled food, there is a higher incidence for gastric carcinoma. So gastric cancers can be increased from eating too many pickled foods. But that's not been exclusively seen with fermented foods. But here's the guidance I give. I tell people not to eat too much of the fermented foods and to treat them as a garnish.

[Sean Ramesh Firm]

Do you think fermented foods could help people with this parasite that gives you explosive diarrhea?

[Dr. Sean O'Meara]

Yes, yes, I really do think so. Because what happens is, you know, the way I think of the gastrointestinal tract, which is the way the medium through which this particular organism is being spread, they're. They're eating foods that are infected with this particular species of pathogenic parasite microbe that's on. On lettuce or still trying to figure out the vectors goes into your stomach.

[Ad Read Announcer]

Stomach.

[Dr. Sean O'Meara]

Well, Sean, if you have living within your stomach a healthier microbiome, they will overcome that particular introduction. But typically what happens to people consuming this is they have what's called a dysbiotic microbiome or what is layman term, a suboptimal microbiome.
