FDA stated in their report "In its recent press release announcing a limited product recall, Evanger’s Dog & Cat Food Company, Inc. stated that the beef for its Hunk of Beef product came from a “USDA approved” supplier. However, the FDA reviewed a bill of lading from Evanger’s supplier of “Inedible Hand Deboned Beef - For Pet Food Use Only. Not Fit For Human Consumption" and determined that the supplier’s facility does not have a grant of inspection from the United States Department of Agriculture’s Food Safety and Inspection Service. The meat products from this supplier do not bear the USDA inspection mark and would not be considered human grade. USDA-FSIS regulates slaughter of animals for human consumption only. Testing by USDA-FSIS of Evanger’s Hunk of Beef confirmed that the meat used in the product was bovine (beef)."
FDA issued 483 (inspectional observations) reports for both facilities [included below], Both reports point out numerous sanitary issues within both facilities. Nothing noted in the reports relates to the issue at hand, but does point out poor execution of sanitary operations. The company tag line - People Food for Pets - not exactly.
In a letter posted on their internet site (posted below), the company blames their supplier.
In a quick internet search, I came by this gem with support.
