Michigan health authorities contacted Yum Brands about a Cyclospora outbreak associated with Taco Bell locations in early July 2026. Documents reported by Bloomberg indicated that officials held a call with the company on July 2 and urged intervention after identifying a strong epidemiological signal. Taco Bell later removed potentially affected ingredients as a precaution, while federal authorities linked the outbreak to Taylor Farms iceberg lettuce. The outbreak reportedly affected more than 6,700 people across 45 states, and subsequent law-firm investigations alleged that Yum Brands may have issued misleading disclosures to investors.
