The recall of dairy products announced last week has been expanded.

Some snack foods containing dairy products made by Rizo Lopez Foods have been added to the list of foods that may be linked to a deadly listeria outbreak. Among the items added to the list include chicken enchiladas, taco kits, cilantro salad dressing and seven-layer dip. The products were sold at stores including Costco, Albertsons/Vons, and Trader Joe's. Dairy products made by Rizo Lopez Foods in Modesto have been linked to an outbreak of listeria that has sickened people and been the cause of two deaths.
