Something in the meat?

So, I noticed that something was amiss in the Oddly Enough section on Reuters. All around the mid-west, calves have been popping out of their mothers with deformities. In two recent cases, it involved one calf with six legs and another with two noses.

Case #1: Calf Born With 6 Legs
Case #2: New Calf Has 2 Noses

Can someone please explain why this is happening? It's extremely disturbing.
