It’s been a choppy year for restaurants that lean into 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.
Taco Bell will likely see the biggest sales impact from the outbreak, which began in late June. Federal health officials first tied the outbreak to shredded iceberg lettuce served at Taco Bell restaurants in Indiana, Kentucky, Michigan, Ohio and West Virginia. Later, the U.S. Food and Drug Administration said customers in Illinois, Kansas, Oklahoma and Pennsylvania were also affected.
Taco Bell said on July 17 that it had voluntarily removed shredded iceberg lettuce supplied by Taylor Farms from its U.S. restaurants. But its customer volume has suffered. As of July 23, Taco Bell visits were 21% lower than average across the U.S., according to Placer.ai, a market research company.
