An Oahu company is voluntarily recalling some 68,670 pounds of ground beef products because they may be contaminated with E. coli.

The announcement of the recall by Palama Holdings of Kapolei comes from the U.S. Department of Agriculture's Food Safety and Inspection Service.

The recall covers a variety of May's beef products produced from April 9 through April 21. They were distributed to retail, food service establishments and commissaries in Hawaii.

The problem was discovered through company testing. Federal officials say no reports of illness have been received in connection with the recalled products.

E. coli is a potentially deadly bacterium that can cause bloody diarrhea and dehydration.
