A recall of Mauri brand Gorgonzola cheese sold by Costco Wholesale Stores in Colorado because of potentially deadly E. coli bacteria, has been expanded to include additional packages, according to the products distributor.

A statement Friday by DPI Specialty Foods of Tualatin, Ore., says the recalled cheese covers clear plastic packages of 1-pound wedges with sell-by dates of Jan. 2 through Jan 27.

The recall announced on Nov. 10, limited the questionable packages to those with sell-by dates of Jan. 13-14. The packages carry a white sticker that reads: “Distributed by DPI Specialty Foods Tualatin, Ore., ITALY 34449.”

The distributor says that the federal Centers for Disease Control and Prevention has not received any reports of illnesses and that testing will indicate whether this bacterial strain is linked to illnesses.
