Avodah Zarah 40: Permitted Foods, from Fish to Apple Wine

A new mishnah! (from the previous daf) Permitted foods, for a change, including milk that was milked by a non-Jew, who was watched by a Jew, and certain fishes, and more. Plus, a deep dive into fish and roe (fish eggs), vs. other seafood, which birth their young (and are not kosher). But some non-kosher fish also lay eggs. Also, the need for experts who were able to determine whether a given fish and its roe were kosher or not. Plus, a story about Rabbi Yehudah HaNasi, his stomach ache, and its cure in non-Jewishly-made 70-year-old non-Jewish apple wine.
