Do you have any Velveeta Shells and Cheese single-serve microwaveable cups in your fridge? Shame on you. Now here's another reason not to eat these gross things: they may have thin wire bristle pieces inside.

No injuries have been reported yet, but Kraft has voluntarily recalled 137,000 units of three product varieties. The original Shells & Cheese cups (single 2.39 oz cups and four cup packs), Shells & Cheese with 2% milk (2.19 oz. cups and four packs) and Rotini & Broccoli (2.44 oz. cups).
