sam: surprising because Rav Shachter told me himself that his research found 96% treifos in milk cows and his son says he stopped eating dairy products 5 years ago. Also, Reb Yudel Shain claims HaRav Elyashiv told him all milk is assur.
First of all why is milk an Aseh, the Gemorra in Bechoros learns it out from “gamal” which is a lav? Also, can you quote any source or example in Issur vHeter where we are more lenient on an Aseh dOraisa than a Lav?
