The U.S. Centers for Disease Control and Prevention says ground beef contaminated with salmonella has sickened at least 16 people in four Northeastern states.

H-E-B supplier Tyson Foods Inc. has issued a recall for nearly 94,000 pounds of Hill Country Fare and H-E-B ground beef products produced at its Amarillo facility that may be contaminated with foreign matter, a mirror-like material, according to the company.
