Taco Bell trims menu as Chipotle shares dip amid rising cyclosporiasis cases

Michigan health officials said the cyclosporiasis outbreak has reached 4,312 reported cases and 121 hospitalizations since late June. The fast-moving gastrointestinal infection, caused by a parasite, has affected residents in 34 states.

In response, Taco Bell announced it voluntarily and temporarily removed lettuce and cilantro from select Michigan locations as a precaution, noting that public health authorities have not confirmed any connection to the chain or a specific ingredient.

Chipotle Mexican Grill saw its shares decline nearly 5% on July 15, although the company has not been linked to the outbreak. A company spokesperson said, ">We are aware of the Cyclospora investigation and at this time, we don’t believe the ingredients we source are associated," and added that the firm is monitoring the situation and prioritizing guest and employee safety.

State health officials continue to investigate fresh produce, particularly salad greens, as a possible source, but have not identified a definitive product. Experts said food safety remains a major concern for consumers and investors.
