Hullin 48: The Local Rabbi Is Far Away

The unusual kashrut halakhic question that was brought from Asia Minor to the land of Israel for an answer. And they repeated the question: whether an animal that had worms in its liver would be kosher or not. Finally, they were told that it was kosher. What about if a needle was found in a lung? Doesn't that render the animal not-kosher/a treyfa? A case of this is brought to explain why it's not a simple answer.
