Manufacturer expands pet food recall March 9, 2010 at 12:31 PM CST - Updated June 19 at 7:10 PM LINCOLN, Neb. (AP) - 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. Salmonella can cause serious and sometimes fatal infections, especially in young children, the elderly and those with weakened immune systems. Pets can also become ill if they consume the bacteria. ___ On the Net: Nature's Variety: http://www.naturesvariety.com Copyright 2010 The Associated Press. All rights reserved.
