Cyclosporiasis outbreaks: What to know about the foodborne illness and symptoms...The source of the illnesses is still unknown, but fresh produce is suspected.

A nasty gastrointestinal bug is rapidly spreading in several states, with more than 700 cases confirmed in Michigan over the last few weeks. The demand for tests for cyclosporiasis, a pathogen often caused by contaminated fresh produce, is so intense, with so many patients seeking help for diarrhea and crippling abdominal cramps, that many labs can’t keep up.

The source of the fast-moving illnesses is unknown, although the Food and Drug Administration said an investigation is ongoing.

Cases in Michigan could easily reach 1,000, said Dr. Anurag Malani, vice chief of staff at Trinity Health Ann Arbor. “There are many more cases that are yet to come.”

Meanwhile, health officials are scrambling to figure out what people are eating that’s making them sick.

“We’re pulling people’s grocery shopping lists,” said Dr. Natasha Bagdasarian, chief medical executive for the state of Michigan. Staff, she said, are working overtime as cases have increased precipitously in recent weeks: 708 cases over the course of about 10 days.

It’s “highly unusual,” Bagdasarian said, as the state usually sees 40 to 50 cases a year.

Cyclosporiasis cases tend to increase during the summer, usually between May 1 and Aug. 31, according to the Centers for Disease Control and Prevention. Most cases are centered in the southeastern part of Michigan, although illnesses have also been reported in Ohio, North Carolina, Illinois and New Jersey, among others.

The FDA and the CDC are monitoring the outbreaks, an FDA spokesperson said in an email. “We are not in a position at this time to characterize the current numbers as definitively unusual pending the completion of that investigation,” the spokesperson said.

The disease — cyclosporiasis — is a foodborne illness caused by a microscopic parasite called cyclospora. Fresh produce is almost always the source. Previous outbreaks have involved raspberries, bagged lettuce or salads, cilantro and basil.

Symptoms include explosive, watery diarrhea. People may also have unusually bad gas, stomach cramps, nausea and loss of appetite.

According to the CDC, 145 cases of cyclosporiasis in 17 states were reported from the beginning of May through June 16, although those numbers are likely a vast undercount.

“CDC has no evidence of a single, multistate Cyclospora outbreak linking cases happening right now and being reported in the press,” a CDC spokesperson wrote in an email.

However, as of July 2025, the CDC made tracking cyclospora optional, as part of scaling back its Foodborne Diseases Active Surveillance Network. At the time, food safety experts worried that it could make it harder to identify and respond to outbreaks.

Dr. Brian Kaminski, vice president of medical affairs at ProMedica Health System, which cares for patients in both southeast Michigan and northwest Ohio, said cases in the two states appear to be part of an “epidemic cluster.”

“When we started seeing cases of persistent diarrhea showing up, we knew there’s something going on,” Kaminski said. “I would say that trend continues.” As of Monday, the ProMedica Health System accounted for 411 cases.

Cyclosporiasis does not spread from person to person, unlike norovirus, a highly contagious stomach bug that usually runs its course in a few days. Left untreated, cyclosporiasis can linger for weeks. It’s treated with an antibiotic, usually Bactrim. Some people have needed to be hospitalized, often from dehydration, Malani said.

No deaths have been reported.

“The question is, where is it coming from, and are all the states connected, or are there multiple outbreaks happening?” said Dr. Matthew Sims, director of infectious diseases research at Corewell Health in Royal Oak, Michigan.

It can take one to two weeks for symptoms to develop after eating contaminated food, which can complicate the investigation.

Bagdasarian said that health officials are asking each patient what restaurants they’ve been to in the past couple of weeks, what they ordered, where they grocery shop and what items they purchased.

Testing in some areas has become strained. “Turnaround time was initially about 24 hours, and we’re two to three days out now,” Kaminski said. If those delays continue, it’s possible that doctors may need to start treating people based on symptoms alone, rather than waiting for confirmatory results.

How to stay safe from cyclospora Rinsing produce can reduce the risk for cyclosporiasis but doesn’t eliminate it. The parasite, cyclospora, “clings to produce,” Kaminski said.

Michigan health officials are encouraging people to buy whole heads of lettuce and remove outer leaves where there could be contamination before washing it.

Raspberries in particular can be difficult to clean because they’re covered in tiny hairs that the parasite likes to hang on.

It’s possible that freezing can kill the parasite, Sims said, but it’s not guaranteed. Cooking food is the only sure way to kill it.

I live in Michiganstan..
I had this ( I did not go to the doctor).
It was caused by Dole bagged chopped lettuce leaves.
I bought 2 bags for salad night at home..
It tasted wrong and went into the trash, but I ate a large salad.
Mrs. Fonebone did not eat the lettuce after the first bite, but she had raspberries, which is what she thinks gave it to her

Think about this:

What do nearly all Americans eat that is almost at every meal in some form or another?

This sounds like what I had last week. But I am pretty sure it did not come from produce.

Interesting!

I bought some bagged chopped lettuce last week and never ate it. After sitting in the fridge for 5-6 days, it looked browned and wilty, so I pulled it out to trash it, and the smell was bad. Often bad produce looks ugly but doesn’t have an overwhelming smell. This did.

Forget Ozempic, this sounds like a much quicker weight loss method.

It appears to have started in my county in Michigan. In one town. The root is so hard to pin down. Personally,
I think it was bagged salad mixes/lettuces from one source. Someplace that delivers to restaurants, too. I don’t think it’s the water because the water goes county wide. We get it, too. No illness here.

I think someone could sell Giardia in capsules for a quick weight-loss program.

I served in Japan for 2 years in the early seventies. I remember that we had an “American” inspector for ALL Japanese farms we (the Navy) bought produce from to use for “chow halls” and snack bars and such on base.

The “American” inspector (a Chief, E-7) was a fellow serviceman who was warned that he would be in huge trouble if he took a bribe and got caught. The Navy’s main concern was that Japanese farmers would use human waste to fertilize their in the ground growing produce.

The FDA and the CDC are monitoring the outbreaks

The remnants of those agencies, at least.

This has happened in the past and will happen in the future. “Fresh produce” sounds healthy but many times it is infested with nasty bugs and gastrointestinal diseases because its not cleaned properly. Its why they tell you to wash fruit thoroughly before you eat it. But its always going to be a problem. My family still laughs about the time that we went out to eat when I was a kid and there was a nasty looking slug in my salad. Salad trauma was my excuse for not eating healthy for years.
