Taco Bell's lettuce sickened 212 people across 21 states — and cost Yum $20M

In July 2026, the CDC and FDA confirmed that shredded iceberg lettuce served at Taco Bell was the source of a Cyclospora outbreak that sickened at least 212 people across 21 states, including Iowa, Illinois, Indiana, Kansas, Kentucky, Michigan, New York, Ohio, Texas and Virginia. At least 94 people were hospitalised. The contaminated lettuce was supplied by Taylor Farms de Mexico.

Taco Bell parent Yum! Brands reported the outbreak cost the chain $15 million to $20 million in lost sales and the expense of removing and replacing lettuce across affected stores. Taco Bell cooperated with the CDC and FDA investigation, pulled the suspect lettuce, and issued public statements emphasising food safety measures. The outbreak was the largest Cyclospora event linked to a single restaurant chain in recent years and exposed the vulnerability of centralised produce supply chains.

A single-source lettuce supply chain meant one contaminated farm shut down salads nationwide, costing $15-20M in lost sales and recall expenses.

A single-source lettuce supply chain meant contamination at one Mexican farm could shut down salads at every Taco Bell in the country

The supply chain was cost-efficient but not resilient — a lesson that applied to every fast-food chain relying on a single produce supplier

A centralised supply chain that saves money every day is an existential risk the day the contamination hits — and that day is a question of when, not if
