The National Beef Packing Co. products, which were shipped nationwide, may be contaminated with E. coli O157:H7, the U.S. Department of Agriculture said Wednesday.
There have been no reported cases of illness.
In an online statement Wednesday, National Beef Packing Co. reported "a voluntary recall for NatureSource Natural Beef, Naturewell Natural Beef and National Beef commodity ground beef." It said the meat was produced on July 18 and has a use by/freeze by date of August 7.
"We are working closely with authorities to investigate this matter and are contacting our customers who have purchased this product," the company said.
