Cyclospora Outbreak Spreads Across US with 145 Cases Reported

States Affected and Case Distribution

The outbreak spans 17 states, with New York at the center, reporting 31 to 80 cases. Other affected states include Illinois, Texas, New Jersey, Pennsylvania, and Michigan, where over 150 cases were reported in southeastern counties as of June 30, 2026. Monroe County, Michigan, alone documented 67 cases, with 14 hospitalizations, according to the Detroit Free Press. The CDC emphasized that no international travel was reported among patients, pointing to U.S.-grown produce as a likely source.

“Local, state, and federal (CDC, FDA) public health authorities are investigating several clusters of cases in more than one state,” the CDC stated, highlighting ongoing efforts to trace the contamination. <a href="https://www.yahoo.com/news/us/articles/parasite-causes-explosive-diarrhea-spreading-201629751.

Symptoms and Transmission Methods

Cyclosporiasis typically presents two to 14 days after exposure, with symptoms including watery diarrhea, loss of appetite, abdominal cramps, and low-grade fever. The illness can persist for weeks without treatment, and some patients experience relapsing episodes. FOX 2 Detroit reported that the parasite is commonly linked to contaminated fresh produce, such as leafy greens, cilantro, and berries, which are often imported from tropical regions.

“The parasite is not known to spread from person to person,” noted the 13abc article, stressing that transmission occurs through food or water contaminated with feces. The CDC advises thorough washing of fruits and vegetables, particularly during summer months when outbreaks peak.

Investigations and Public Health Response

Michigan’s Department of Health and Human Services (MDHHS) is coordinating with local health departments to identify a common exposure, as reported by the Detroit Free Press. In Monroe County, health officials are interviewing patients and analyzing food sources, though no specific product has been pinpointed. “We are currently investigating the source,” said Lindsay Patrick of the Monroe County Health Department.

The CDC has also issued warnings to healthcare providers, urging them to test for Cyclospora in patients with prolonged gastrointestinal symptoms. “The true number of cases is likely higher than reported, as some individuals recover without medical care,” the agency noted. <a href="https://www.dailyvoice.

Historical Context and Prevention

Cyclosporiasis outbreaks in the U.S. have historically been tied to imported produce, such as the 2019 basil outbreak and 2018 McDonald’s salad incident. New York Post highlighted these precedents, noting that the current investigation has yet to identify a specific food source. The CDC recommends avoiding raw or undercooked produce and ensuring proper refrigeration to reduce risk.

“Washing all fruits and vegetables thoroughly under running water is critical,” advised the FOX 2 Detroit article. Health officials also urged individuals experiencing symptoms to seek medical care promptly, as untreated infections can lead to severe dehydration.

“I felt like I was dying,” said Lisa Vanhoose, a Monroe County resident who was hospitalized after contracting the parasite. WXYZ reported her account, emphasizing the severity of the illness even in non-fatal cases.

What’s Next? Ongoing Challenges

Despite efforts by federal and state agencies, the source of the outbreak remains unidentified. The CDC and FDA continue to collaborate with local health departments, but tracing the contamination to a specific food product or supplier has proven difficult. “This is a complex investigation,” said a spokesperson for the Michigan Department of Agriculture and Rural Development. <a href="https://www.freep.
