This Planet Money episode explores the Cyclospora outbreak linked to Taco Bell and Taylor Farms lettuce, tracing the dual revolutions of the industrial lettuce industry and food safety regulation. It highlights how bagged salad transformed lettuce into a multi-billion dollar commodity, while the FDA's struggle to regulate farms and lack of resources perpetuate recurring outbreaks.
