Between prices and a diarrhea-causing parasite, lettuce is causing hard times at some restaurants

Lettuce prices and a cyclospora outbreak linked to shredded iceberg lettuce are impacting restaurants, with Yum Brands reporting a 2% decline in Taco Bell's same-store sales. The outbreak, traced to Taylor Farms' lettuce, led to recalls and temporary sales drops, though sales have partially recovered. Other chains like Chipotle and Sweetgreen also report reduced traffic or spending amid the crisis.
