HolyMoe: If you are going to go that route then you need to hold like R’ Schachter. Because even in the Chalav Yisrael farms it doesn’t change the fact that more than 1.6% of cows are naturally Triefos. So you’d be violating an Issur (an Issur Asei actually, if I recall what R’ Schachter said correctly, but close enough) D’Oraisa whenever you have Chalav Yisrael products as well.
(And doesn’t R’ Belsky have a piece explaining why those aren’t an issue and why the OU can certify Chalav Stam without worrying about that?)
