Two People in Michigan Die from Cyclospora
This is the largest cyclosporiasis outbreak in U.S. history, linked to Mexican lettuce served at Taco Bell, and the number of infected continues to rise.
This is the largest cyclosporiasis outbreak in U.S. history, linked to Mexican lettuce served at Taco Bell, and the number of infected continues to rise.
Michigan's Department of Health confirmed on Monday, August 3, 2026, the first deaths associated with the cyclosporiasis outbreak in the United States. Two individuals from Michigan have died from complications of the severe intestinal illness caused by the microscopic parasite Cyclospora, authorities reported.
The deceased individuals had significant underlying health conditions that, combined with severe dehydration and intestinal illness, led to fatal outcomes. These are the first known victims of an outbreak that has reached record proportions, with Michigan being the epicenter.
As of Monday, Michigan had recorded 11,234 cases, an increase of 461 since Friday, with 193 hospitalizations. Wayne County, which includes Detroit, has the highest number of cases (1,379), while Washtenaw County has reported 875.
The U.S. Food and Drug Administration (FDA) has linked the outbreak, confirmed in nine states, to iceberg lettuce from a Mexican facility operated by the private company Taylor Farms. The lettuce was served at the fast-food chain Taco Bell, owned by Yum Brands. The facility in Doctor Mora, in the state of Guanajuato, was temporarily closed on July 24.
However, epidemiologists suspect multiple sources of infection. "We have one clearly implicated food, but it doesn't explain everything," said Susan Ringler Cerniglia, spokesperson for the Washtenaw County Health Department. It has not yet been confirmed whether the deceased individuals were infected from that lettuce or from another, as yet unidentified source.
The response to the outbreak is further complicated by contradictory messages from the top. Spokesperson Cerniglia sharply criticized statements by U.S. Secretary of Health and Human Services, Robert F. Kennedy Jr. "Leadership is saying things that don't quite align with what the data tells us, and that's very, very problematic. The Secretary is saying everything is under control and everything is fine while the number of cases is exploding," she said.
The Centers for Disease Control and Prevention (CDC) had recorded 6,707 laboratory-confirmed cases of cyclosporiasis nationwide as of July 28, along with more than 11,500 suspected cases awaiting confirmation. State-level numbers are even higher because the CDC excludes probable cases.
Experts warn that cuts to federal health agencies are hampering the response. "It certainly doesn't help to have underfunded or understaffed public health departments," said Dr. Paul Bollyky, professor of infectious diseases at Stanford Medicine. He added that the scale of the outbreak raises broader questions about food safety: "Whenever you have more than 10,000 people infected with a foodborne pathogen, you have to ask yourself if this is a canary in the coal mine."
Cyclosporiasis is an intestinal illness caused by the parasite Cyclospora. It manifests as severe watery diarrhea with frequent and sometimes explosive bowel movements, nausea, and other serious gastrointestinal issues. "This development underscores the importance of identifying the source of the outbreak and preventing additional illnesses," said Wade Syers, a food safety specialist at Michigan State University Extension.
The outbreak has already impacted consumer confidence, reducing lettuce sales and visits to restaurant chains like Sweetgreen and Chipotle.
