Rental Cars in Hilo, Hawaii soaked with chlorpyriphos

On the afternoon of July 31, 1993, Joey Walker applied a granular fire-ant killer called Green Light to his yard in Liberty Hill, Texas. Dressed in a T-shirt, jeans, and boots, Walker was using a hand-held spreader–just as the label instructed–and inhaled the compound, absorbed it through his sweaty skin, or both. That evening, he collapsed on the sofa, complaining of flulike nausea, fatigue, and headache. In April 1994, he  suffered a grand mal seizure while watching his oldest son play Little League baseball. "He turned blue," his wife, Margaret, recalls. "All his muscles drew right up, like the Incredible Hulk." Walker was in and out of hospitals for 15 months. In August 1995, he was admitted to a nursing home, where he remains in a vegetative state. Walker had used Green Light without incident the year before he got sick. Does this mean, as Relford says, that "hypersensitivity just doesn't hold up"? Or does it mean, as Abou-Donia theorizes, that the effects were cumulative? Walker, now 43, is oblivious.  "He can look around," his wife says, "but we're not sure what he sees."
