Nebraska-based Nature’s Variety has expanded a recall of their pet food due to concerns of salmonella contamination.

The company had initially recalled packages of chicken-based foods 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.

The products included in the Nature’s Variety recall include three-pound packages of chicken medallions, six-pound packages of chicken patties and two-pound packages of chicken chubs.
