Still smarting from this fall's E. coli outbreaks, the produce industry is trying to coax Americans into eating their greens again with high-tech solutions. Companies like Dole and Western Growers are using radio-frequency tags and GPS surveillance to track veggies as they move from farm to grocery store.
But being able to identify the source of contamination may not prove as valuable to consumers as preventing it in the first place. But skeptics say tracking on that end isn't coordinated. "It's almost like 9/11, and all the different responders have different frequencies so they can't talk to each other," says a lawyer who represents food poisoning victims.
