Rabbi Juravel begins with discussing the sugya in the gemara Avoda Zarah prohibiting milk that was not watched by a Jew. He discusses what constitutes "watched" according to halacha, which brings him to discuss the heter of the Pri Chadash and the chiddush of Rav Moshe Feinstein  (Chazon Ish).  Also mentioned is Rav Elyashiv`s psak to the OU if Rav Moshe`s hetter applies European milk factories as well.  Also discussed is the duration of time that is needed for a yisroel to be there during the process.
