Let me preface this with: My understanding is less than nothing about this or any Halachic topic.This is not the forum for final Halacha, our Rabbis are the ones to ask, I just want help to understand this until I ask my Rabbi. Please don’t infer anything from what I post either way. (or from anyone else here who is not your Rabbi)
That said, Isn’t The very reason for the Heter of Cholov Stam in America because the goy would be scared to loose his business if caught switching cows milk with non kosher milk ?
If yes then it would seem the reason for the Heter ( This incentive ) is no longer applicable with DD, as they where caught switching and there was no consequence, In addition now that they saw they can switch (in their mind) “the more kosher milk” with “the less kosher milk” they may feel no problem with switching an ingredient if need be ( like pig fat or lard for kosher oil etc )
IMHO today where you can buy CY milk almost anywhere in America why take a chance with one who has been caught not being truthful ? If you say you ( like me ) know nothing , perhaps its better not to post kulos that you don’t know so much about ( like me ) unless you do and have semicha on a public forum……So as not to run into the problem of Lifney Iver
In short always ask you Local Orthodox Rabbi for the Halacha in this or any case.
