The United States is currently facing its most severe outbreak of the Cyclospora parasite in history, with infection numbers in 2026 exceeding those in 2019, which held the previous record. Lettuce and salad greens are suspected as sources of the contamination.
Recent data shows infections have been detected in over 30 states nationwide, with Michigan being the hardest-hit area, reporting more than 3,300 cases. Public health officials have yet to definitively identify the outbreak's source but preliminary findings suggest lettuce and salad greens as potential carriers.
Taco Bell, a well-known restaurant chain, issued a statement saying it has voluntarily removed certain ingredients from stores in affected areas temporarily as a precaution. The company confirmed it will closely monitor the situation and comply with public health authority guidance.
However, U.S. federal public health officials have not confirmed that the investigation targets any specific restaurant, retail chain, or supplier, nor have they verified any connection to Taco Bell.
The U.S. Centers for Disease Control and Prevention (CDC) explains that Cyclospora is a tiny parasite living in the intestines that causes Cyclospora infection. Patients usually experience severe watery diarrhea and frequent bowel movements; some may suffer explosive diarrhea, abdominal pain, nausea, fatigue, and weight loss. The disease is generally not life-threatening and can be treated with antibiotics.
Experts note that outbreaks typically occur in late spring and summer because this parasite thrives in warm conditions. It spreads through fecal contamination and has historically been linked to consuming fruits or vegetables exposed to contaminated irrigation water.
Although Cyclospora infections are less common than bacterial food poisoning from Salmonella or E. coli, public health officials are urgently investigating the outbreak source to prevent further case increases during this summer.
