Nationwide Beef Recall 
U.S. Food Safety and Inspection Service has announced a recall on 16,000 pounds of beef products that were sold at Walmart stores nationwide over a possible E. coli contamination.
Six ground beef products produced by Cargill Meat Solutions of Pennsylvania are being recalled after a “segregated product” was inadvertently used to make ground beef patties.
All of the recalled products have “EST. 86P” printed on the back of the label.
You’re advised to throw any of the beef away. Also, clean and sanitize any areas the beef may have touched.
