Taco Bell Recovers Sales After Foodborne Illness Outbreak

Taco Bell's U.S. sales are showing a significant recovery following a summer outbreak of cyclosporiasis linked to lettuce, which had impacted customer traffic. The chain's parent company, Yum! Brands, reported a 4% decline in same-store sales during the third quarter (July-September), marking the first quarterly drop in approximately six years.

This downturn was partly due to a 20% decrease in weekly foot traffic during the outbreak's peak. However, Taco Bell has since seen its U.S. same-store sales increase by about 1% in the fourth quarter, outperforming the broader quick-service restaurant industry. Executives attribute this resurgence to effective value offerings, loyalty program promotions, and successful partnerships with entertainers.

The cyclosporiasis outbreak, investigated by federal and state health officials, was traced to shredded iceberg lettuce from a single supplier in Mexico. Cyclospora cayetanensis, a parasite causing gastrointestinal illness, was identified as the cause. Taco Bell voluntarily removed select ingredients as a precaution during the investigation, which concluded in September.

Looking ahead, Yum! Brands anticipates Taco Bell will maintain its positive momentum through the end of 2026 and into 2027, continuing its focus on affordable menu items and new products to attract a broad customer base.
