Taco Bell restaurants are temporarily removing several fresh ingredients from their menus due to a nationwide surge in cyclosporiasis, an intestinal illness caused by the Cyclospora parasite. The outbreak has led to nearly 2,000 reported cases across the United States, with symptoms including "watery diarrhea" and "frequent and sometimes explosive bowel movements."
Locations, including some in the Metro Detroit area, have posted signs indicating that lettuce, cilantro onion, pico de gallo, and guacamole are unavailable. The notices state that items normally containing these ingredients will be served without them. These components are integral to popular Taco Bell menu items such as tacos, the Crunchwrap Supreme, and Cantina Chicken offerings.
It remains unclear if any Taco Bell customers have fallen ill from the parasite. The menu adjustments come as health officials investigate the widespread increase in cyclosporiasis cases.
Michigan has reported 992 cases linked to the outbreak, a significant rise from its typical annual count of around 50. New York City has confirmed 273 cases since May 1 and 301 cases in total for 2026, according to the city's Health Department.
The Centers for Disease Control and Prevention notes that symptoms can persist for a month or longer. Other common symptoms include stomach cramps, nausea, bloating, fatigue, appetite loss, and weight loss. While most individuals recover without specific treatment, health officials are examining potential links to outbreaks in Ohio, North Carolina, Illinois, Colorado, Texas, Florida, and Connecticut, though the definitive source has not yet been identified.
Authorities are advising consumers to thoroughly wash all fresh produce, maintain cleanliness of kitchen utensils and surfaces, and to cook raw produce when feasible to mitigate risks.
