Some Taco Bell locations, including in Metro Detroit, are temporarily withholding fresh ingredients such as lettuce, pico de gallo, guacamole and cilantro onion amid a widening cyclosporiasis outbreak. Michigan has reported 992 cases and Ohio more than 500, while officials say the source has not yet been identified.

Some Taco Bell locations are temporarily pulling fresh ingredients from service as public health officials continue investigating a widening cyclosporiasis outbreak that has sickened nearly 2,000 people across the U.S.

The menu changes have been reported at affected restaurants, including locations in Metro Detroit, where notices said items such as lettuce, pico de gallo, guacamole and cilantro onion were unavailable. The ingredient changes mean some menu items cannot be served as usual.

Officials have not publicly identified the outbreak source, and there is no confirmed public link between Taco Bell customers and illnesses tied to the parasite. The restaurant changes appear to be precautionary while investigators work through the traceback.

Outbreak grows

The Associated Press reported Tuesday that Michigan had 992 cases, including about 40 hospitalizations, in what state officials described as the largest cyclosporiasis outbreak recorded there. Ohio has reported more than 500 cases, including 306 in Lucas County alone.

Public health investigations are also continuing in 28 other states, underscoring how broadly the outbreak has spread. Michigan officials have said the state typically sees about 50 cyclosporiasis cases in a year, making the current total highly unusual.

Cyclospora is a parasite that spreads through food or water contaminated with feces. The illness commonly causes prolonged watery diarrhea and is often associated with fresh produce.

What Taco Bell locations are doing

People and the New York Post reported that some Taco Bell locations posted notices saying they were temporarily unable to serve lettuce, pico de gallo, guacamole and cilantro onion because of a nationwide recall. The notices said affected menu items would not include the unavailable ingredients.

The reporting did not indicate that the change was chainwide. Instead, it pointed to a limited response at some locations in the affected area, particularly in Metro Detroit.

That distinction matters because the public-health investigation has not yet identified a specific ingredient or distributor as the source. The menu changes may therefore evolve as more is learned.

What investigators are watching

State health officials and the CDC are still trying to narrow the source of the outbreak. A confirmed traceback could lead to a recall, additional menu restrictions or broader supply-chain changes if a particular produce item is identified.

People reported that other heavily affected jurisdictions include New York, North Carolina, Illinois, Colorado, Texas, Florida and Connecticut. That geographic spread suggests the issue is not confined to one local market.

For now, the most important point is that the outbreak response is still developing. The restaurant notices are a consumer-facing sign that operators are already adjusting menus while health authorities continue the investigation.

What comes next

Investigators are still trying to determine the source of the outbreak, and health officials may yet name a specific produce item or distributor. If that happens, restaurants and suppliers could face additional menu restrictions or a recall notice.

Consumers in affected areas should watch for local notices from restaurants and updates from state health departments and the CDC as the traceback continues.

For now, the outbreak remains active, the source remains unknown, and some Taco Bell locations are removing fresh ingredients as a precaution.
