Diamond Pet Foods issued a voluntary recall of its Diamond Naturals Lamb Meal & Rice formula as a precautionary measure because the product has the potential to be contaminated with Salmonella.

The petfood manufacturer says the dog food recall is a voluntary measure and that no illnesses have been reported and none of the company's other petfood products are affected.

The recall applies to Diamond Naturals Lamb & Rice formulas sold in 6-lb., 20-lb. and 40-lb. bags. The 6-lb. bags are marked with a "Best Before" date of January 4, 2013, and production code of DLR0101D3XALW; the 20-lb. bags are marked with a "Best Before" date of January 3, 2013, and production code of DLR0101C31XAG; and the 40-lb. bags are marked with "Best Before" dates of January 3, 2013, and January 4, 2013, and production codes of DLR0101C31XMF, DLR0101C31XAG and DLR0101D32XMS.

The recalled products were distributed in the United States in Alabama, Florida, Georgia, Kentucky, Maryland, Michigan, New York, North Carolina, Ohio, Pennsylvania, South Carolina and Virginia, USA, but may have been distributed through other petfood channels in other states.
