There’s a stomach bug working its way across the country right now, and the culprit isn’t undercooked chicken or some sketchy gas station hot dog. It’s fresh produce. The kind of stuff you toss in your cart without a second thought. As of mid-June, federal health officials counted 145 people sick in 17 states from a parasite called Cyclospora, and that number tends to climb as the season rolls on.
Here’s the kicker. Investigators still don’t know which food did it. Not the brand, not the farm, not even the specific item. People got sick, the lab work came back, and the source is still a giant question mark. Let me walk you through what’s actually happening, why this one is so slippery, and what’s worth knowing before you build your next salad.
Here’s What The Outbreak Looks Like Right Now
The numbers, as of June 16, 2026: 145 people got sick after eating food in the United States, spread across 17 states. Ages run from 5 to 86, with the median sitting right around 42. About 61% were women. Twenty of them ended up in the hospital. No deaths have been reported.
The first person got sick on May 1, the last reported onset was June 6, and the median onset date was May 13. There’s a separate group too: 45 more cases in people who picked it up while traveling outside the country, but those are a different story. Nobody in the main group reported any international travel in the two weeks before they got sick. That means whatever they ate, they bought it here at home.
The Usual Suspects In The Produce Aisle
Investigators haven’t named the food yet, but this parasite has a long rap sheet. Past U.S. outbreaks have been tied to basil, cilantro, leafy greens, raspberries, and snow peas. Bagged salad kits keep showing up too, especially the Caesar kind loaded with chopped romaine.
Back in 2020, a bagged salad outbreak made 701 people sick across 14 states. So when you hear the phrase “fresh produce,” picture the pre-washed clamshells of mixed greens, the bunches of herbs by the misters, the cartons of berries. The current pattern lines up with those same categories. But until the traceback work wraps up, nobody can point at a specific package on a specific shelf.
Why Nobody Can Pin Down The Source
This thing is a nightmare to trace, and there’s a strange biological reason for it. When Cyclospora gets shed into the environment, it can’t make anyone sick right away. It has to sit in warm, damp conditions for one to two weeks before it becomes infectious. Only then can it contaminate food or water.
Now stack that on top of the roughly seven days between eating it and feeling sick. You’ve got a huge gap. By the time someone is in a doctor’s office getting tested, the produce they ate is long gone. Eaten, tossed in the trash, or pulled from shelves weeks ago. The trail goes cold before it even starts. For outbreaks in 2023 and 2024, which together topped 3,000 cases, investigators never nailed down exactly how the contamination happened. That’s how tough these are.
Rinsing It Off Won’t Do Much
This is the part that catches people off guard. Giving your greens a good rinse won’t save you. Food safety experts say there is no evidence that washing produce removes this parasite. It clings on, and a quick spin in the salad spinner just isn’t enough to knock it loose.
That flips a lot of grocery store logic on its head. We’ve all been trained to think a thorough wash buys us peace of mind, and for plenty of stuff it helps. With Cyclospora, the rinse-and-relax routine doesn’t carry the weight you’d hope. It’s not about how dirty the leaf looks. The contamination is microscopic, and it doesn’t come off easy.
Summer Is Basically Open Season
Cyclospora has a season, and we’re right in the middle of it. Cases climb in the warm months, and officials treat May 1 through August 31 as the cyclosporiasis window. This year it kicked off right on schedule, May 1.
The warmth and humidity of summer are exactly what the parasite needs to mature out in the environment, which is why these outbreaks bunch up between late spring and early fall. July is usually the busiest stretch. So that 145 number you’re reading about now? Don’t be surprised if it keeps growing through the rest of the season. Case counts almost always tick up before they settle down.
This Stomach Bug Plays Mind Games
What makes this one rough isn’t just the symptoms, it’s how long they hang around. Most food poisoning hits hard and clears up in a day or two. Cyclospora doesn’t play that way. According to health agencies, the watery diarrhea can drag on for weeks, even a month or more if it’s left untreated.
And it messes with your head. People feel like they’re finally turning the corner, then it comes roaring back a few days later. That on-again, off-again pattern makes it tough to know when you’re actually in the clear. Other reported symptoms include cramping, bloating, loss of appetite, nausea, and just feeling completely wiped out. Things usually start about a week after you eat the contaminated food, which is part of why folks rarely connect the dots back to a salad.
What You Can Actually Do About It
So what do you do with all this? Don’t panic, for starters. Most healthy people get through it, and there’s a standard treatment doctors reach for once it’s identified. The catch is that the usual stomach-bug remedies don’t touch this one. So if you’ve had watery diarrhea for more than a week after eating a pile of fresh greens or herbs, it’s worth bringing up Cyclospora by name with your doctor. It takes a specific stool test to catch, not the standard panel.
Beyond that, there’s no clever trick to pull at the grocery store, since the source hasn’t been made public and washing won’t fix it. The FDA and CDC are still digging through traceback data, and the moment they name a product, that’s when you’ll want to dig through your fridge and check what you’ve got. Reporting is also voluntary in some places, so the real count is almost certainly higher than 145. Plenty of people ride it out at home and never get tested.
For now, the smartest thing you can do is simply know this bug is out there. Know what it looks like, know why it lingers, and know why a single bowl of greens can land 20 people in the hospital before anyone can say which greens. When the investigation finally names a culprit, you’ll be miles ahead of the panic. Keep an eye on your herbs, your salad kits, and your berries, and don’t write off a week of stomach trouble as just bad takeout.
