It’s been a difficult year for restaurants that rely heavily on lettuce. Lettuce prices rose sharply in the first half of 2026 due to hot weather in Arizona, where about one-third of America’s lettuce is grown. Now, restaurants are dealing with the fallout from a cyclospora outbreak linked to shredded lettuce that has sickened thousands of Americans.

Impact on Restaurants

Yum Brands, the parent company of Taco Bell, said Thursday that Taco Bell’s U.S. same-store sales are down 2% so far in the July-September period due to customers’ concerns over the outbreak. That compares to a 7% same-store sales increase in the April-June period.

Federal health officials first tied the diarrhea-causing outbreak to shredded iceberg lettuce served at Taco Bell restaurants in several states. Later, the U.S. Food and Drug Administration said customers in additional states were also affected.

Taco Bell removed shredded iceberg lettuce supplied by Taylor Farms from its U.S. restaurants on July 17. The following day, Taylor Farms recalled iceberg lettuce grown in central Mexico.

Industry Challenges

The outbreak came on top of an already difficult year for the lettuce industry. The retail price of a pound of iceberg lettuce jumped nearly 20% between January and June of this year, according to government data. Consumers paid an average of 33% more last month for all fresh lettuce compared to a year earlier.

Elizabeth Canales, an associate professor of agricultural economics at Mississippi State University, said unusually hot weather in Arizona early in the year caused crops to mature too early. That caused big supply gaps until California production began in late April.
