Dole Food company has issued a recall of bagged salad that may have been sold in parts of Mississippi.
The recall comes after a sample tested positive for E. coli, but the company says it has received no reports of illness.
The voluntary recall affects all packages of Dole's Hearts Delight salad mix sold in the United States and Canada.
The packages in question have a "best if used by" date of Sept. 19, 2007, and a production code of "A24924A" or "A24924B."
The product was also sold in parts of Canada, and the states of Illinois, Indiana, Maine, Michigan, Virginia, New York, Ohio, Pennsylvania, Tennessee and neighboring U.S. states.
A company spokesman says the romaine, green leaf and butter lettuce hearts in the blend were grown in California, Colorado and Ohio. They were processed at a Dole's plant in Ohio.
