Following a voluntary recall last week, JBS Swift Beef Company of Greeley, Colorado announced over the weekend a significant expansion. The initial recall, announced on June 24, covered of 41,280 pounds of whole-muscle cut beef products that may have been contaminated with E. coli O157:H7 bacteria. On Sunday, the company voluntarily expanded the recall to cover an additional 380,000 pounds of specific products produced on April 21, 2009.

A JBS release notes that while the product was distributed as whole muscle cuts, some of this product was likely further processed through trimming and grinding into ground beef by customers.

According to USDA, some of this ground product might have been associated with illness.

The list of whole muscle cut beef products subject to the recall is available on the USDA’s Food Safety and Inspection Service website.
