Cases of cyclosporiasis in Michigan surpass 5,000, health officials say

(NEW YORK) — Hospitalizations in Michigan linked to an outbreak of cyclosporiasis, an intestinal illness caused by a parasite, have surpassed 100, health officials said Friday.

So far, 102 people have been hospitalized, according to the Michigan Department of Health and Human Services (MDHHS). There are more than 5,000 cases in the state, an increase of nearly 700 since Thursday, officials said.

The Centers for Disease Control and Prevention and the Food and Drug Administration are warning consumers not to eat shredded iceberg lettuce sold at select Taco Bells in five states — Indiana, Kentucky, Michigan, Ohio, and West Virginia — after the ingredient was linked to the outbreak. The CDC said that shredded iceberg lettuce sold in grocery stores or served in other restaurants is not affected. 

Lettuce supplier Taylor Farms said it is voluntarily removing all iceberg lettuce sourced from central Mexico from the U.S. market.

Taylor Farms said the FDA traceback indicated a “specific farm” that accounts for “less than 1% of the U.S.’s iceberg lettuce supply” was a potential source, and they have removed all iceberg lettuce from the region indefinitely. No other Taylor Fresh Food products have been impacted and that no branded salad kits contain iceberg lettuce, Taylor Farms said. 

“As a family owned and operated company, we are deeply concerned for those who became ill, their families, and the many Americans whose trust in the safety of their fresh produce has been shaken. That trust is something we’ve worked for decades to earn, and we are committed to doing everything in our power to restore that confidence,” Taylor Farms said in a statement Friday.

Preliminary findings by Michigan health officials suggest lettuce or salad greens are the potential source of the illnesses. However, no specific type of produce, grower or supplier has been identified as the source, and federal health officials have not publicly identified a source of the outbreak.

The White House said on Thursday it is “closely monitoring” the cyclosporiasis outbreak and “has a handle on the situation.”

Press secretary Karoline Leavitt said the White House is working with the FDA and partners at the federal, state and local levels to “increase detection methods,” provide guidance and trace the outbreak.

On Tuesday, Taco Bell said it would voluntarily remove some ingredients at select restaurants as a precautionary measure.

“The health and safety of our guests is our top priority,” Taco Bell Corp said in a statement to ABC News. “Public health officials have not confirmed a link to Taco Bell or any specific ingredient, supplier, restaurant or retailer. While authorities continue their broader review, Taco Bell has voluntarily and temporarily removed limited ingredients at select restaurants as a precautionary measure. We will continue to closely monitor the situation and follow the guidance of public health authorities.

Federal health officials said cases of cyclosporiasis will continue to rise in the U.S. The season is typically considered to be from May 1 to Aug. 31.

Additionally, the CDC sent out an alert to doctors around the country on Tuesday warning them of an increase in cases of cyclosporiasis.

Michigan health officials previously told ABC News the outbreak could be linked to food contamination.

Earlier this month, MDHHS sent out recommendations to restaurants and other commercial kitchens in southeast Michigan to reduce risks of exposure.

MDHHS data shows that most cases have been among adults, with 30 to 39 year olds making up the highest share.

The outbreak was first identified on June 29, when the Monroe County Health Department announced it was investigating a cluster of cases.

The parasite usually spreads through food or water contaminated with feces, according to the Centers for Disease Control and Prevention. It does not typically spread person-to-person. 

Foodborne outbreaks of cyclosporiasis in the past have been linked to various types of imported fresh produce, such as raspberries, basil, snow peas, mesclun lettuce and cilantro, according to the CDC.

At least 31 other states have reported cases of cyclosporiasis, according to an ABC News tally, analyzing CDC data and state health department data.

Cyclosporiasis is treated with the oral antibiotic trimethoprim-sulfamethoxazole (TMP-SMX), commonly sold as Bactrim, Septra and Cotrim, and taken for 10 days, according to the CDC.

The agency says people can prevent infection by thoroughly washing produce, cutting away bruised or damaged parts of fruits and vegetables and refrigerating pre-prepared or pre-cut produce.

Additionally, the CDC recommends washing hands thoroughly with soap and water before handling or preparing raw fruits and vegetables.

Trump gets a much-needed South Carolina win and other takeaways from Tuesday’s elections

(CNN) — President Donald Trump demonstrated his might with Republican primary voters Tuesday in South Carolina, as CNN’s Decision Desk projected that Darline Graham — the sister of the late Sen. Lindsey Graham and the president’s pick in the state’s special Senate primary runoff — will claim the GOP nomination.Now favored to win a full term in November, Darline Graham is, in many ways, a senator of Trump’s own making. The president lobbied South Carolina’s governor to appoint her to fill the remaining months in her brother’s term after he died in July. Then, he privately and publicly pressed her to run for a full six-year term.And when it looked like her rival in the runoff, Rep. Ralph Norman, might win, Trump visited Myrtle Beach to rally Republican loyalists to Graham’s cause, as his super PAC, MAGA Inc., disclosed spending more than $827,000 to support Graham.Graham’s win is narrow — she led by just a few percentage points Tuesday evening — but symbolically significant for the president in a month full of political setbacks, with six of his endorsed picks losing Republican primaries.Trump’s preferred candidate in the Oklahoma governor’s race, former state Sen. Mike Mazzei, meanwhile, was locked in a close Republican primary runoff against state Attorney General Gentner Drummond as ballots were being counted Tuesday night.And in a low-turnout special election runoff in Georgia, Democrats filled a vacancy in the narrowly divided House.Here are takeaways from Tuesday’s elections in South Carolina, Oklahoma and Georgia:A badly needed win for TrumpDarline Graham took to the stage at her victory party Tuesday night and declared: “South Carolina is truly Trump country.”Unlike her brother, who was close to the late Sen. John McCain and built a reputation as a foreign policy hawk independent from Trump, Darline Graham’s political profile was tied entirely to the president.“Our victory would not have been possible without you, and we are truly grateful,” she said in a message directed at Trump.For Trump, the win was badly needed — a victory in one of his highest-risk interventions in Republican primaries this year, after a string of several losses this month and with midterm elections just over two months away. It could serve to remind Republican lawmakers who might be looking to distance themselves from an unpopular president of the potential political costs of being at odds with Trump.Norman acknowledged Trump’s role in the race’s outcome, telling his supporters Tuesday night that “the president got involved. He has that right.”“I never understood why he got in this race,” Norman said as some members of the crowd booed the president. “But it is what it is, and I’ll accept it.”Graham is now set to face Democratic nominee Annie Andrews, a pediatrician, in November. Andrews on Tuesday challenged Graham to at least three televised debates, saying in a statement that “no appointment, endorsement, or family connection entitles anyone to six years” in the Senate. Still, Graham is heavily favored to win the deep-red state in the general election.A senator of Trump’s makingTrump has endorsed a slew of candidates this year, but rarely has he put his own political capital on the line like he did in South Carolina.When Trump initially talked up Darline Graham to fill the seat of her late brother, and Gov. Henry McMaster complied, it seemed like a short-term gig. The seat was already on the ballot for a full six-year term in November, so she’d have been a placeholder for a few months, until South Carolina voters nominated and elected one of the state’s myriad experienced Republicans who had been waiting decades for a Senate vacancy.But Trump doubled down three days after she was sworn in, urging her on social media to seek a full term. And, days later, she announced she would do so.The president’s “complete and total endorsement” wasn’t enough to clear the field. After all, Darline Graham had no political experience, and her brother wasn’t exactly beloved among conservative voters in South Carolina: He’d earned just 57% of the vote in his primary two months earlier against a handful of relative unknowns.The results of the August 11 primary suggested she could be defeated in the runoff. She finished first, but with just shy of 33% of the vote.There were reasons to believe Trump’s influence might be limited. After all, his choice in South Carolina’s GOP primary for governor, Lt. Gov. Pam Evette, lost to state Attorney General Alan Wilson — who Trump also endorsed at the last minute when it was clear his preference was on course for defeat.The president did not have the luxury of the same face-saving tack here: Norman had endorsed and campaigned with former Gov. Nikki Haley as she ran against Trump for the 2024 GOP presidential nomination.Graham’s inexperience was on display during a debate with Norman earlier this month, when she declined to answer a question about Taiwan and the South China Sea, saying that national security was “not my thing.”But Trump carried Graham over the finish line. He visited South Carolina on Friday, telling Republicans that he’d personally lobbied her to run for a full term. “Pretend, please, that I’m on the ballot,” he urged GOP voters.Another endorsement test in OklahomaAnother Trump-endorsed candidate, Mazzei, was locked in a tight race Tuesday night against Drummond in the hard-fought runoff for the Republican nomination for governor.The two are vying to take on Oklahoma House Minority Leader Cyndi Munson, the Democratic nominee, in the race to replace term-limited Republican Gov. Kevin Stitt in November.The race was another test of Trump’s influence — and there were significant questions over whether his endorsement would be enough for Mazzei, after Trump’s picks in Republican gubernatorial primaries in Georgia, Iowa and Minnesota all lost earlier this year.A key divide in the primary was a proposed $4 billion aluminum smelter at the Tulsa Port of Inola, estimated to bring about 1,000 jobs to the area. Trump touted the plant, claiming on Truth Social that it “will be one of the best projects ever conceived or built, not only in the Great State of Oklahoma, but in the United States, itself.” But, amid local concerns about pollution and damage to the livestock economy, Drummond has sued, asking a federal court to block the plant’s construction.Georgia Dems fill a House seatCNN projects that Democrat Everton Blair, a former Gwinnett County School Board chair, will win the special election for Georgia’s 13th District House seat vacated by the late Rep. David Scott’s death in April.But he won’t hold that seat for long.Blair, who will be the first out gay member of Congress from Georgia, defeated the longtime lawmaker’s daughter Marcye Scott in the special election runoff on Tuesday. He campaigned on a pledge to be a stronger opponent to Trump and advocate for a more progressive affordability agenda than both the late congressman and his daughter.However, Blair finished a distant third in the regular House primary earlier this year, so he won’t be on the ballot in November.State lawmaker Jasmine Clark is the Democratic nominee for a full two-year term in the deep-blue district in November. She did not run in the special election because under state law, she would have had to resign her seat in the Georgia House — costing Democrats a seat just as Republican Gov. Brian Kemp was launching an unsuccessful push for mid-decade redistricting.In the meantime, Blair’s win, and the special election of state Sen. Aisha Wahab in California last week, will help Democrats further narrow the already razor-thin GOP majority in the House.CNN’s Katie Doran and Adam Cancryn contributed to this report.The-CNN-Wire™ & © 2026 Cable News Network, Inc., a Warner Bros.
