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 is threatening new Canadian auto tariffs. That will hurt US automakers and workers

(CNN) — President Donald Trump’s threat of 50% auto tariffs on all imports from Canada is just the latest action to rattle an industry that’s endured shifting trade rules since he returned to office.Trump issued the auto tariff plans early Monday, just as trade tensions between the two neighbors ratcheted up. On Saturday, the US slapped 50% tariffs on a much more limited group of Canadian exports after efforts to strike a deal collapsed.But the steep auto tariffs, if enacted, could disrupt long-established business practices and have far-reaching consequences across the auto industry, experts say.“Sweaters, honey and hockey sticks are not a trade war. What the president just threatened this morning is a trade war,” said Patrick Anderson, CEO of Anderson Economic Group, a Michigan-based consulting firm. “It would be a body blow to the auto industry. We would see plants closing on both sides of the border.”Canada does have a large trade surplus with the United States. But when it comes to the auto industry, it’s the opposite — the US has a nearly $1 billion a month trade surplus with Canada.America imported $24.5 billion worth of Canadian vehicles and auto parts in the first six months of this year, according to Commerce Department trade data, compared to the $30.4 billion Canada imported.Since the North American Free Trade Agreement was first introduced in the 90s, and then the US-Mexico-Canada Agreement during Trump’s first term, the auto industry has been able to operate as if North America is a single market. Companies move parts and vehicles freely across borders, often multiple times before the car is assembled and sent to dealer showrooms.Even with last year’s auto tariffs, that process continued. That’s because carve outs allowed Canadian-made parts and vehicles to remain more or less tariff free.Disrupting that flow will cost US jobs, both for the auto parts industry and at assembly plants.“The impact of unworkable tariffs would be felt well beyond Canadian assembly plants,” said Erin Keating, executive analyst with Cox Automotive.Cars built at Canadian plants depend heavily on parts from US suppliers, which employs more than half a million Americans.And Canadians bought about 663,000 cars built at US assembly plants last year, according to research firm Mobility Global. Canadian buyers also spent more than three times as much on larger, more expensive vehicles — heavy trucks, buses and special purpose vehicles — than American buyers.Most major automakers contacted by CNN either had no comment on the tariffs or did not respond to a request for comment.Unifor, the union that represents Canadian auto workers, blasted the planned tariffs, calling them an “intimidation tactic.”“The US administration fails to recognize that our highly integrated auto industry means ongoing instability hurts workers on both sides of the border and makes it increasingly difficult to build cars in North America,” the Canadian union said. “We need to resolve this, together.”The-CNN-Wire™ & © 2026 Cable News Network, Inc., a Warner Bros.
