Sotah 29 - Can you ask him?
"If sacrificial meat comes into touch with something impure, then it cannot be eaten; otherwise, a ritually clean person may eat it."
The beginning of the phrase says that impure meat is not eaten. So we understand that doubtfully impure meat can be eaten. But the end talks about pure meat that may be eaten. And we can derive that doubtfully pure meat cannot be eaten. So now we have two contradictory indications, whether one can eat doubtfully pure meat. You can only explain it if you say that the doubt is prohibited when it refers to a human, who can be asked, and allowed if it refers to the meat itself, which obviously cannot be questioned.
