Three days earlier, Mars Petcare US (Franklin, TN) recalled two dry dog food products because of potential contamination from Salmonella Schwarzengrund. Products affected include five-pound bags of Krasdale Gravy dog food sold in Connecticut, Massachusetts, New Jersey, New York and Pennsylvania, and 50-pound bags of Red Flannel Large Breed Adult Formula dry food sold in Pennsylvania.
