Got “EST 31913” ?

Well there is a major beef recall (825,769lbs) on bearing that code number. And, hmm...can't say the exact brand name of the beef because "these products were repackaged and sold under different retail brand names."

A Fresno-based beef company is recalling hundreds of thousands of ground beef products that may be linked to a salmonella outbreak, the U.S. Department of Agriculture’s Food Safety and Inspection Service announced today.

The 825,769 pounds of ground beef products, produced by Beef Packers Inc. from June 5 through June 23, bear the code “EST 31913” and were distributed to Arizona, California, Colorado and Utah, USDA officials said in their recall statement. - Latte Times

It's up to the consumer to find out whether they have that beef or not.
