SAN FRANCISCO (AP) — A package of Dole salad mix that tested positive for E. coli has triggered a recall in at least nine states, prompting new produce fears almost exactly a year after a nationwide spinach scare.The tainted bag of Dole's Hearts Delight salad mix was sold at a store in Canada, officials said. Neither Canadian health officials nor Dole Food Co. have received reports of anyone getting sick from the product.The voluntary recall, issued Monday, affects all packages of Hearts Delight sold in the United States and Canada with a "best if used by" date of September 19, 2007, and a production code of "A24924A" or "A24924B," the company said.Last year, an E. coli outbreak traced to bagged baby spinach sold under the Dole brand was blamed for the deaths of three people and for sickening hundreds more across the U.S. Authorities eventually identified a central California cattle ranch next to spinach fields belonging to one of Dole's suppliers as being the source of the bacteria.A recent Associated Press investigation found that government regulators never acted on calls for stepped-up inspections of leafy greens after that outbreak, and regulations governing farms in the fertile central California region known as the nation's "Salad Bowl" remain much as they were.
