Nature's Variety has expanded its recall of chicken-flavored pet food because of concerns over salmonella.
The Lincoln, Neb.-based company said Monday that the raw, frozen food is being recalled because it could be contaminated with salmonella.
The recall includes three-pound packages of chicken medallions, six-pound packages of chicken patties and two-pound packages of chicken chubs.
Initially, the company recalled only packages with a best-by date of Nov. 10, 2010. Now packages with best-by dates of Oct. 29
and Nov. 9, 2010, are also being recalled.
