Check your cheese: Shredded and grated varieties are recalled nationwide

Several varieties of shredded mozzarella and other cheese blends, sold at retailers including Aldi, Target and Walmart, are being recalled over concerns they were contaminated with bits of metal.

The FDA is urging customers to toss certain brands of grated Pecorino Romano; at the same time, it escalated an existing recall of numerous shredded cheeses.
