One Great Burger of Elizabeth, NJ, is expanding its Jan. 10, 2011 recall to include an undetermined amount of additional ground beef products that may have become spoiled, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced Friday.

The frozen hamburger patties subject to the recall are considered adulterated because the establishment’s food safety plan was inadequate to produce safe product, the FSIS said in a news release.

The products were produced between April 2010 and May 2010 and were distributed to grocery stores in Alabama, Florida, Georgia, Louisiana, and Mississippi. While the products listed above have been unavailable for purchase since May 2010, consumers who may have purchased them are urged to remove them from their freezers and discard them
