Cyclospora is a parasite causing severe gastrointestinal illness currently linked to contaminated lettuce at Taco Bell locations in five states, according to the CDC. The outbreak has affected more than 30 states, with Michigan reporting the highest volume of cases, exceeding 5,000 reports as of Thursday.
Michigan Reports Highest Case Volume in Multi-State Outbreak
Michigan is the hardest-hit state in the current cyclosporiasis outbreak. According to the state’s Health and Human Services department, more than 5,000 cases have been reported, with over 100 individuals requiring hospitalization.
The parasite is concentrated in the Detroit area. Wayne County reported nearly 600 cases as of Thursday, while Oakland County reported just under 400. Ingham County, home to Lansing and Michigan State University, also reported approximately 400 cases.
Did you know? Cyclospora is often referred to as the “explosive diarrhea” parasite due to the severity of the gastrointestinal symptoms it triggers.
Contamination Linked to Taco Bell Locations in Five States
The CDC has identified contaminated lettuce served at Taco Bell locations as a source of the parasite. This link specifically affects five states: Indiana, Kentucky, Michigan, Ohio, and West Virginia.
In Kentucky, the Department for Public Health reported 108 confirmed cases and seven hospitalizations, according to Louisville Public Media. The majority of these cases are concentrated in Jefferson County, where Louisville is located.
Underreporting Trends in Illinois and Indiana
Health officials suggest that official case counts may not reflect the full scale of the outbreak. In Illinois, where 216 cases and 18 hospitalizations were reported, Dr. Alfredo Mane Lora of St. Anthony Hospital told WGN that these numbers are “the tip of the iceberg.” Lora noted that many infected individuals experience mild symptoms or see the illness self-resolve without seeking medical care.
Indiana has reported 366 cases as of Friday. The Indiana Department of Health identified the Indianapolis and Fort Wayne areas as the primary hotspots, with 40 cases each.
Ohio Health Warnings and Hospitalization Data
As of July 2, Ohio reported 171 cases and 28 hospitalizations. The highest concentration of cases was found in Lucas County (including Toledo), which recorded 30 cases by that date.
Ohio Department of Health Director Bruce Vanderhoff stated in a July 2 news release that while there have been no deaths in Ohio, the illness is serious. Vanderhoff warned that the parasite can cause severe dehydration requiring emergency medical care and urged residents to wash all fruits and vegetables thoroughly.
Pro Tip: Always scrub produce and consider using a produce brush for firm vegetables.
