United Food Group, LLC, of Vernon, California, is voluntarily expanding its prior recalls to include a total of approximately 5.7 million pounds of both fresh and frozen ground beef products produced between April 6 and April 20 because they may be contaminated with E. coli O157:H7.

The recall is being expanded out of an abundance of caution following a positive test of fresh ground beef subject to this recall provided by a patient in Arizona.

The fresh and frozen ground beef products subject to recall were shipped to retail stores in Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming.
