Michigan health officials are investigating a growing outbreak of cyclosporiasis that has sickened 2,640 people, with early evidence pointing to lettuce or salad greens as a possible source.

The Michigan Department of Health and Human Services said Monday (July 13) that while the investigation is ongoing, no specific type of lettuce, grower, or supplier has been identified.

Other food items also have not been ruled out.

“Although we do not have a definite product identified as the source of the outbreak, we want to let Michiganders know what we have learned so far so they can take steps to protect their families,” said Dr. Natasha Bagdasarian, the department’s chief medical executive. “Early information has shown lettuce as a common product that regularly comes up during the investigation.”

What is Cyclospora?

Cyclospora is a parasite that infects the intestines and can cause watery diarrhea, nausea, and stomach cramps.

The illness is typically spread by consuming food or water contaminated with the parasite.

Michigan usually reports only 40 to 50 cases of cyclosporiasis each year, making the current outbreak unusually large.

What investigators know

State health officials said they have completed more than 1,000 interviews with infected individuals while working with local, state, and federal partners to trace the source of the outbreak.

“We really need that kind of coordination to happen at the national level,” Bagdasarian said. “As soon as other states get their numbers to the CDC, we hope they can take a broader look to see whether these outbreaks are related.”

Because symptoms can take up to two weeks to develop after exposure and food distribution networks are complex, officials said the investigation could take time.

Officials emphasized there is no evidence linking the outbreak to swimming or other recreational water activities. Instead, investigators continue to focus on contaminated produce as the likely source.

Previous cyclospora outbreaks in the United States and Canada have been linked to bagged salad mixes, fresh cilantro, basil, raspberries, snow peas, and green onions.

Health officials said the investigation has been complicated by cyclospora’s long incubation period, with symptoms often taking up to two weeks to develop after exposure.

“That means investigators have to ask people about foods they ate, restaurants they visited, and grocery purchases from two to six weeks earlier,” Bagdasarian said.

How to protect yourself

As a precaution, the department is urging residents, restaurants and commercial kitchens in affected counties to take extra care when handling lettuce and salad greens.

Health officials recommend purchasing whole heads of lettuce instead of bagged, pre-washed lettuce or salad kits, discarding the outer two to three leaves before preparation and thoroughly washing the remaining leaves under clean running water.

When possible, greens should be cooked to at least 158 degrees Fahrenheit (70 degrees Celsius), which kills the parasite.

The department also recommends washing all fresh produce under running water and peeling fruits and vegetables when possible.

People at higher risk of severe illness or dehydration, including older adults, young children, organ transplant recipients and people undergoing chemotherapy, are encouraged to take extra precautions.

“Produce may have been grown on the other side of the country, possibly even in other countries, then processed somewhere else before coming into Michigan,” Bagdasarian said. “Many suppliers also distribute produce to multiple grocery stores and restaurant chains, making it harder to pinpoint the source.”

When to seek medical care

Anyone experiencing frequent watery diarrhea should contact a health care provider and specifically request testing for cyclospora, as routine stool tests may not detect the parasite.

The illness is typically treated with antibiotics, along with rest and fluids to prevent dehydration.

The Michigan Department of Health and Human Services said it will continue providing updates as the investigation progresses.

GRAND RAPIDS, Mich. — Outgoing Michigan Sen. Gary Peters is endorsing U.S. Rep. Haley Stevens as his successor, adding to a growing effort by the Democratic establishment to help her defeat progressive favorite Abdul El-Sayed in next month’s primary.

Peters, who is retiring after 12 years in the Senate, said Stevens “will be ready on day one to fight for Michigan.” The endorsement, which was announced Monday, marks a reversal for Peters, who told The Associated Press in late May that he intended to stay neutral in the race.

But since then, Democratic leaders have increasingly rallied behind Stevens as the Aug. 4 primary approaches and concerns grow that El-Sayed is too far left to succeed in November. Holding the Michigan seat is viewed as critical to Democrats’ hopes of reclaiming the Senate majority.

Stevens, a four-term House member, has campaigned as a more moderate Democrat focused on manufacturing issues in the critical battleground state. El-Sayed, who has never held elected office, is running on a more progressive platform that includes Medicare for All and campaign finance reform. He’s also been outspoken about the war in Gaza, which has been a fault line within the party.

Concerns about Michigan have only intensified after Democrats’ attempt to flip a Senate seat in Maine was thrown into turmoil when nominee Graham Platner withdrew from the race following a sexual assault allegation last week. Democrats there must now choose a new nominee to face Republican Sen. Susan Collins.

Peters’ endorsement also comes after state Sen. Mallory McMorrow dropped out of Michigan’s Democratic primary earlier this month, transforming the race into a head-to-head contest between Stevens and El-Sayed.

“Senator Peters knows what it takes to win in Michigan, and he knows what Michigan needs from our next U.S. Senator: grit, effectiveness, hard work, and Michigan common sense,” Stevens said in a statement. “I am honored to have his support.”

Peters won two Senate races in Michigan and led Senate Democrats’ campaign arm during the 2022 and 2024 election cycles.

His endorsement adds to Stevens’ growing support from the Democratic establishment, with the race being viewed nationally as a broader fight over the party’s direction.

Senate Democratic leader Chuck Schumer of New York has also backed Stevens, along with Sen. Ruben Gallego of Arizona and Sen. Catherine Cortez Masto of Nevada. El-Sayed has support from Sen. Bernie Sanders of Vermont and, more recently, Sen. Chris Van Hollen of Maryland.

The campaign has grown increasingly contentious in recent weeks.

El-Sayed has attacked Stevens over tens of millions of dollars in outside spending supporting her campaign, including by the American Israel Public Affairs Committee. Stevens has criticized El-Sayed for not disclosing his personal financial records.

During a July 7 debate, each accused the other of running a negative campaign.

“Abdul has spent this entire campaign attacking me,” Stevens said.

The Democratic winner will likely face Republican Mike Rogers, a former member of the U.S. House running uncontested for his party’s nomination, in what is expected to be one of the country’s most expensive and closely watched Senate races.

SOUTHFIELD, Mich. – Whether it’s a church, mosque, synagogue, houses of worship have long been viewed as sanctuaries and safe havens.

But with violent incidents such as the attack on the LDS Church in Grand Blanc last fall and the attack on the Temple Israel in West Bloomfield back in March, they are facing a new and scary reality balancing safety with worship

“People in congregations like to feel when they come to church, that they’re safe,” Rev. Chris Yaw, the pastor at St. David’s Episcopal Church in Southfield, said on Sunday morning. “They wanna feel like this a place I can come to where I can be myself, not have to worry about gun violence…”

He brought members of the Southfield Police Department after 10:00 a.m. service to talk about emergency planning and situational awareness, all to help parishioners stay vigilant in the off-hand chance something bad happens.

“Because (violence) is such a new and disheartening unfolding of events, we wanna make sure to bring the experts in to tell us what we should be looking at,” he said.

While crime overall in houses of worship remains low, according to the non-partisan Violence Prevention Project, there were 399 violent incidents in houses of worship here in the United States between 2000 and 2025 – resulting in 512 deaths and 213 injuries.

“The thing that people need to understand is that you cannot stop living,” Southfield Police Lt. Teresa Young said. “You do need to be more aware of your surroundings. If something doesn’t feel right in your heart, your soul, your belly, then follow those instincts.”

Young helped lead the event this morning. It’s similar to programs that the Detroit Police and Michigan State Police have run over the last year

“I feel safe coming here,” parishioner Elizabeth Greene said. She was flanked by her little sisters and is relatively new to this church. While she feels safe worshipping here, it is a new experience that won’t change things for her.

“I’ve never experienced a church giving education about their safety protocols,” she said. “Just being aware of it is enough.”
