Some Taco Bell locations in Metro Detroit have stopped serving lettuce, cilantro onion, pico de gallo and guacamole while health officials investigate a large cyclosporiasis outbreak in Michigan, Ohio and other states.

Some Taco Bell locations in Metro Detroit have stopped serving several fresh ingredients, including lettuce, cilantro onion, pico de gallo and guacamole, while health officials investigate a growing cyclosporiasis outbreak.

Posted notices at the affected restaurants said items normally ordered with those ingredients would not include them. The reporting reviewed so far does not show a confirmed link between Taco Bell customers and the illness outbreak.

The change appears to be part of a broader response to a fast-moving public health investigation rather than a confirmed restaurant-specific source.

What health officials are investigating

Cyclosporiasis is a foodborne illness caused by the Cyclospora parasite. Investigators are still trying to identify the source of the outbreak, and the reporting reviewed so far does not tie it to a specific ingredient or supplier.

Associated Press reported that Michigan has nearly 1,000 cases and about 40 hospitalizations. Ohio has more than 500 cases, including 306 in Lucas County, and investigations are ongoing in 28 states.

The outbreak has been described as one of the largest recent U.S. cyclosporiasis investigations, but the source has not yet been identified.

How the reporting unfolded

People first reported on July 8 that some Taco Bell locations had stopped serving certain fresh ingredients amid the outbreak. The New York Post followed on July 9 with similar reporting about ingredient removals at Metro Detroit locations.

A later check on July 9 confirmed the wider outbreak context, including the multi-state scope and the case totals cited by AP.

Those reports are consistent on the basic point that some locations have changed what they can serve while public health officials continue their investigation.

What is known and what is not

The notices reported by journalists said items ordered with the affected ingredients would not contain them. The notices also referred to a nationwide produce recall, but AP coverage of the outbreak did not identify the source.

It is not clear from the reporting whether the ingredient removals are limited to Metro Detroit or broader than that.

There is also no confirmed public reporting yet that Taco Bell customers have become sick from the outbreak.

Why it matters

Cyclosporiasis is typically associated with contaminated food or water, often fresh produce. That makes restaurant ingredient changes and supply-chain questions central to the investigation.

The situation affects consumers who may see menu substitutions, as well as investigators trying to determine whether a particular produce item or distributor is involved.

For now, the immediate public-health concern is preventing additional exposure before the source is identified.

What happens next

The next developments to watch are whether CDC or state health officials identify the source, whether Taco Bell or its suppliers issue a fuller statement, and whether more states report cases or hospitalizations.

Health officials will also be watched for any confirmation that the outbreak is tied to a specific produce item or supplier.

Until then, the outbreak remains an active multi-state investigation with temporary menu changes at some restaurant locations and no confirmed source.
