A recall is in effect for nearly 50-tons of ground beef products from HEB supplier Tyson Foods. The recall was announced Wednesday. It involves five and ten-pound chubs of Hill Country Fare 73% lean ground beef, and five-pound chubs of HEB 80% lean ground chuck. About 94,000 pounds of meat may be contaminated with foreign matter, described as a mirror-like material. The products were sold at HEB and other stores with a freeze-by date of November 25th. The recalled items have been removed from store shelves. HEB customers who bought them can return them for a full refund.
