5、On Jan. 13th, 2009, the Peanut Corporation of America issued a recall (召回) for products it had made over the past six months, after five people had died and more than 400 had fallen ill with salmonella（沙门氏菌）poisoning as a result of contamination. Two weeks later, the recall was extended to more than 400 consumer products made since Jan. 1, 2007, including Jenny Craig nutritional bars and Keebler Peanut Butter Sandwich Crackers, while the toll from the contamination had reached eight dead and more than 500 sickened in 43 states, half of them children.
   The company's factory in Blakely, Ga., which was the source of the contamination, supplied some of the largest food makers in the nation. The outbreak showed the complexities of the industrial food chain, and left consumers to figure out if some food in their cabinets had a danger. The recall of peanut products is the latest in a series of increasingly severe food contamination scares involving tomatoes, spinach, cantaloupes and other foods.
   The Georgia plant, which is closed, packed peanut butter in bulk ranging from 5 to 1,700 pounds, much of which was shipped to institutions. Many school districts have pulled peanut butter from menus, with some substituting more commonly recognized supermarket brands. New York City school officials said they had not bought any peanut butter or products with ingredients that originated at the Georgia plant.
   An F.D.A. inspection team that visited the plant on Jan. 9 discovered that on 12 occasions in 2007 and 2008 tests conducted by the company found salmonella contamination in its products but that it shipped the contaminated products to customers after a retest found no contamination and did nothing to clean the plant.
