July 21, 2026 ~ Mark Miller, owner of Little Camille’s by the Green, discusses whether concerns surrounding the Cyclospora outbreak are influencing what consumers are purchasing and eating.
MICHIGAN ~ A parasitic outbreak in Michigan ballooned to 6,571 cases Monday, with the source of the month-long outbreak still unknown after a test of lettuce sold at some Taco Bell restaurants done by the Food and Drug Administration gave a false positive for Cyclosporiasis.
Taylor Farms, a produce supplier that sells lettuce to Taco Bell locations, was seen as the likely culprit for the outbreak, but the false positive found Sunday leaves the case with no clear source. Taco Bell is continuing to recall its lettuce, however.
Most of the Michigan cases are concentrated in the southeast, with a total of 34 states a part of the outbreak.
Cyclosporiasis is commonly spread by food or water contaminated with feces. In recent years, outbreaks have occurred in the U.S. as a result of eating contaminated fresh produce, especially during the summer months. Cyclosporiasis is not known to spread from person to person. Symptoms occur two to 14 days after exposure and may include watery diarrhea, loss of appetite, abdominal cramps, bloating, nausea, and mild fevers.
Individuals experiencing sudden gastrointestinal illness are encouraged to be evaluated by a health care provider. Symptoms of cyclosporiasis can be significantly improved with antibiotic treatment. If untreated, the illness may last for a few days to a month or longer. Providers are urged to consider cyclosporiasis among patients presenting with acute gastrointestinal illness in southeast Michigan.
To help avoid any illness from Cyclospora or other harmful bacteria or organisms, public health officials recommend the following:
- Wash all fruits and vegetables thoroughly under running water before eating, cutting or cooking.
- Scrub firm fruits and vegetables, such as melons and cucumbers, with a clean produce brush.
- Cut away any damaged or bruised areas on fruits and vegetables before preparing and eating.
- Refrigerate cut, peeled or cooked fruits and vegetables as soon as possible.
- Cook when you can, since heating food to 158°F or higher kills Cyclospora.
