A meat supplier has greatly expanded a ground beef recall, which now includes about 5.7 million pounds of fresh and frozen meat that may be contaminated with E. coli. The beef, sold in 11 Western states, was distributed by California-based United Food Group LLC.

David Goldman, acting administrator of the USDA Food Safety and Inspection Service, announced on Saturday that the recall would be expanded to include products with sell-by dates from April 6-April 20.
