From AP story of this morning: E. coli Find Shows Difficult Mix Of Cattle, Spinach
Bill Marler, a Seattle lawyer representing 93 people who got sick eating spinach and the families of two who died, said processors and packagers of greens are also responsible for ensuring their safety.
"From a victim’s perspective, Dole, Natural Selection and this farm are on the hook," Marler said. "It’s their collective responsibility to step up and deal with these claims."
This story also has a great video.
