An excerpt from Barry Easterbrook's Tomatoland captures the bizarre alternate world of tomato growers in Florida:

In this world, slavery is tolerated, or at best ignored. Labor protections for workers predate the Great Depression. Child labor and minimum wage laws are flouted. Basic antitrust measures do not apply. The most minimal housing standards are not enforced. Spanish is the lingua franca. It has its own banking system made up of storefront paycheck-cashing outfits that charge outrageous commissions to migrants who never stay in one place long enough to open bank accounts. Pesticides, so toxic to humans and so bad for the environment that they are banned outright for most crops, are routinely sprayed on virtually every Florida tomato field, and in
too many cases, sprayed directly on workers, despite federally mandated periods when fields are supposed to remain empty after chemical application.  

The article is a greatest hits from the food movement canon--terrible labor practices team up with heavy use of pesticides and fertilizers to produce a nutritionless, tasteless final product. While the broad strokes of the story sound familiar, the details of the tomato industry in Florida seem particularly alarming.

While agricultural working conditions are widely known to be horrible, some tomato pickers in Florida are subjected to forced labor--slavery. Conventional agriculture is known for its use of pesticides and fertilizers, but Florida tomato growers use particularly awful chemicals in especially large quantities to compensate for growing a desert plant in the swamp. Grocery store produce is bland and flavorless compared to anything from a garden, but because tomatoes are picked green and bred to survive trips on a truck, they have the lowest customer satisfaction of any produce item.

If you want to avoid participating in this system, Easterbrook has one solution that I would strongly endorse: "The best way to experience true tomato taste is to grow your own."
