Reports of people sickened in the outbreak have occurred between Sept. 3 and Dec. 31, 2008, with most illnesses starting after Oct. 1. About 18 percent of those who fell ill were hospitalized.
The strain of salmonella has been identified as Salmonella Typhimurium, the most common of the more than 2,500 types of salmonella bacteria in the United States. It's often found in uncooked eggs and meats, said CDC officials.
The recall and the potential link to the multi-state outbreak come two years after ConAgra recalled its Peter Pan brand peanut butter, which had been linked to at least 625 salmonella cases in 47 states.
