    Lettuce Liability

    Little more than a year ago, supermarkets from coast to coast stripped fresh spinach from produce aisles as a food-poisoning outbreak swept the nation. From mid-August through September 2006, virulent bacterial infections sickened at least 204 spinach consumers. Five died and 30 others suffered acute kidney failure.
