A Pennsylvania food manufacturer is recalling 8,757 pounds of ready-to-eat salad products following an E.coli outbreak that has spread to several states and sickened dozens of people. The Food and Drug Administration said Friday that the outbreak, which began in mid-March, may have been caused by bagged and pre-chopped romaine lettuce grown in Yuma, Arizona,region, near the border to Southern California. The agency had not identified specific farms or companies that grew, supplied, and distributed the contaminated vegetables. Thirty-five people from 11 states have become sick; 22, including three people suffering from kidney failure, have been hospitalized. The majority of them reported that they ate romaine lettuce within a week before they became sick. The highest number of illness was reported in Idaho and Pennsylvania, with eight and nine cases and seven were reported ill in New Jersey. The others were in Washington state, Missouri, Illinois, Michigan, Ohio, New York, Virginia and Connecticut.
