San Francisco (AP) Dole Food Company has issued a recall of bagged salad.
It 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 September 19, 2007, and a production code of "A24924A" or "A24924B."
The product was sold in Ontario, Quebec and the Maritime Provinces in Canada. It was also sold in Illinois, Indiana, Maine, Michigan, Mississippi, 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 Dole's plant in Springfield, Ohio earlier this month.
