Michigan health officials say the state’s cyclosporiasis outbreak has grown to more than 1,500 cases. 

As of July 10, the Michigan Department of Health and Human Services has received 1,562 reports since June 22. Health officials say 44 people have been hospitalized. 

Cyclospora cayetanensis is a parasite that causes the diarrheal illness cyclosporiasis. The Centers for Disease Control and Prevention says the most common symptoms associated with the illness are frequent watery diarrhea, loss of appetite, bloating, nausea and fatigue. Some people may also experience body aches, headache or vomiting.  

The outbreak of the gastrointestinal illness was first reported in late June, after the Monroe County Health Department said it was investigating a cluster of cases. 

Most of the cases have been in Southeast Michigan, with multiple cases reported in Jackson, Lenawee, Livingston, Oakland, Shiawassee, Washtenaw and Wayne counties. As of July 9, cases have been confirmed in 40 counties, with Monroe County reporting the most, at 215. 

Michigan averages about 50 cases per year, according to MDHHS.    

According to the CDC, at least 31 states have reported cases since early May, including IllinoisNew York, and Texas.

MDHHS recently launched a cyclosporiasis outbreak webpage, where case counts are updated daily by 11 a.m. ET. The state will provide an update on hospitalization status and detailed outbreak data on Thursdays. 

What’s causing the outbreak?

Health officials are still working to determine the cause or causes of the recent burst in cases, whether that be a supplier, grower or type of produce.

According to MDHHS, previous outbreaks in the U.S. and Canada were linked to bagged salad mixes, fresh cilantro, fresh basil, raspberries, snow peas and scallions.

Considering the trends, state health officials recommend that restaurants and commercial kitchens in Southeast Michigan take additional precautions with fresh produce, including washing it under clean running water and cooking it when possible.

Tips to prevent cyclosporiasis

Health officials shared the following tips for avoiding the illness:

  • Wash all fruits and vegetables thoroughly, under running water, before cutting, cooking or eating.
  • Scrub firm fruits and vegetables, such as melons and cucumbers, with a produce brush when cleaning.
  • Cut away any damaged or bruised areas of produce before preparing and eating.
  • Refrigerate any cut, peeled or cooked produce within two hours of preparing it.

Trump’s vaccine order is counterproductive and ‘wrong on so many levels,’ GOP lawmaker says

(CNN) — Republican Sen. Bill Cassidy, an increasingly sharp critic of President Donald Trump, on Sunday called the president’s vaccine order to separate injections for measles, mumps and rubella “wrong on so many levels” because, among other things, it would require children to receive more shots.“Let’s just take it from the perspective of the parent,” Cassidy, a doctor who chairs the Senate’s Committee on Health, Education, Labor, and Pensions, said during an interview on CNN’s “State of the Union” show. “Now, instead of going to the doctor twice to get their child vaccinated, they have to go six times … Instead of mom or dad missing work twice, you know, coming out of their pocket, if you will, to take their child to the doctor, they have to miss work or take vacation or personal leave six times. This is inconvenient. It’s going to contribute to an increased loss of income.”“The president’s proposal is going to end up with more children being sick. And so who wants that? No one should want that,” Cassidy said.During a later appearance on ABC News’ “This Week,” the Louisiana senator said: “This is why the president’s poll numbers are down, because you’ve lost sight of affordability for the parent, you’ve lost sight of the convenience for the American family, you’ve lost sight of that which is driving higher costs in health care.”CNN has reached out the White House for a reaction to Cassidy’s criticism.Trump’s order says the combination vaccine that protects against measles, mumps and rubella, called MMR, “should be administered in three separate single-disease shots,” and all childhood immunizations should be given at separate medical visits.Immunologists and vaccine experts say there’s no valid reason to do that.“Nothing bad can happen from what we are doing,” Trump said while speaking in the Oval Office on Monday. “The worst thing that could happen would be nothing happens. We’re not going to lose anything.”The executive order marked the latest blow for Cassidy, who cast a deciding vote to confirm Robert F. Kennedy Jr. as Health and Human Services secretary despite deep concerns about his anti-vaccine views.Ahead of that confirmation vote, Cassidy secured a series of commitments from Kennedy — including that the two would have an “unprecedentedly close collaborative working relationship” and Kennedy would not seek to undermine the government’s vaccine policies.But Kennedy began testing that pact within months, overhauling the government’s main vaccine advisory panel and amplifying skepticism of key vaccine policies — all while downplaying what has grown into the worst measles outbreak in the country in decades.Their already-frosty relationship hit a breaking point late last year, after the abrupt firing of the then-head of the Centers for Disease Control and Prevention and Kennedy’s subsequent push to revamp the nation’s childhood vaccine schedule.Kennedy’s allies later joined Trump in openly backing a primary challenge to Cassidy that successfully denied him renomination earlier this spring.Since then, Cassidy has shown far greater willingness to criticize Trump and Kennedy, opposing the president on key issues such as the Iran war and his effort to establish an “anti-weaponization” fund. Cassidy and Kennedy’s relationship is effectively non-existent, people close to the two men said, and the two have rarely spoken in the last several months.Still, Cassidy has stressed that despite feeling freer to express his views, his final months in the Senate are not meant to serve as a revenge tour.That did not prevent him on Sunday from lashing out at the president’s latest policy, which he has also done in a series of social media posts.“If it wasn’t so potentially tragic, you would break out laughing at a comment like that,” Cassidy, told CNN’s Jake Tapper about Trump’s claim that nothing would happen as a result of what experts say is a dramatic reshaping of US vaccine policy.“As a physician who has seen people either die or get seriously ill from diseases that can be prevented by vaccines, this has the potential to decrease the protection that a child would receive against diseases which can be deadly,” Cassidy said.He added that if Trump is looking to improve children’s health while helping parents with costs, “this is the wrong thing to do.”The-CNN-Wire™ & © 2026 Cable News Network, Inc., a Warner Bros.
