Lettuce prices surge, outbreak sours restaurant sales

Lettuce has become a costly ingredient for some restaurants this year, with prices soaring in early 2026 due to hot weather in Arizona, a key growing region. This sharp increase in costs has been compounded by a widespread cyclospora outbreak, which has sickened thousands of Americans and been linked to shredded lettuce.

Taco Bell, a major chain, has felt the impact directly. Yum Brands, its parent company, reported a 2% dip in U.S. same-store sales for the July-September quarter, a stark contrast to the previous quarter's 7% increase. Federal health officials traced the outbreak to shredded iceberg lettuce served at Taco Bell locations in several states. The company removed the affected lettuce on July 17, and the supplier, Taylor Farms, recalled its product grown in central Mexico the following day.

Despite initial sales declines, Taco Bell has seen improvement. Yum Brands executives noted that the company's swift action and clear communication, along with promotions like $1 Mexican pizzas, helped restore consumer confidence. "With respect to the consumer sentiment, we've seen real improvement as consumers have understood better the nature of the issue," said Yum Brands CFO Ranjith Roy. "They understand that it is not a Taco Bell specific issue."

Other restaurant chains are also experiencing fallout. Chipotle Mexican Grill revised its same-store sales forecast downward, anticipating only a 1% rise instead of the previously expected 3%. Salad-focused chains like Chopt and Sweetgreen have also reported decreased foot traffic and spending, underscoring the broad impact of the outbreak on the dining industry.
