"It’s the peak of the leafy greens growing season in Yuma, Ariz., where irrigated valleys are lush and verdant amid cactus-covered mountains. This is America’s Salad Paradise, which produces most of the fall and winter lettuce consumed in the United States.
Locals credit excellent soil, preposterously abundant sunshine and a steady supply of labor, thanks to Mexicans with work visas who cross the border checkpoint and ride buses to the fields.
But these are anxious times for the leafy greens industry, and the partial federal government shutdown and furloughing of many Food and Drug Administration officials has deepened the distress."
