Published in 1903 (could have been written a number of years before, it’s not dated)
What’s Rabbi Yosef Fried referring to, and on what grounds to you think Rav Moshe wouldn’t consider that sufficient?
A. Thank you for the M"M. The original poster was alleging that Rav Moshe was the first one to write down a 'widely accepted psak for dorei doros" that had never been written down... To which I stated that thats an unreasonable premise...
B. I don't know who Rabbi Yosef Fried is, or where lived... (or which sefer your quoting
) but yes, we need to research what he was refering to,and if he possibly could have been mistaken on what the koach of the Govt supervision was. Remember, "The Jungle" which was an expose of, among other things, the compleate failure of govt food regulations at the time was published in 190
5.
This is a short history of US dairies...
https://dairymarkets.org/PubPod/Reference/Library/Weimar&Blayney.1994.pdfWhen would YOU say "Company" milk (as opposed to private, farmer) starts? wheen does regulation/inspections start?
C. I'm not taking any position on anything in the sugya at all. There are way bigger TC on this forum who can do that. I'm just commenting on flaws I see in the way the OP sees the historical record.
Of all people you choose to showcase Rav Henkin? He clearly writes that many are meikal because of government supervision.
Actualy, My GGF. Rav Henkin told him that his chidushim were a bridge too far.
https://hebrewbooks.org/pdfpager.aspx?req=1554&st=&pgnum=5Rav Moshe writes clearly that תלמידי חכמים and יראי שמים were not machmir btw
And yes, they were being meikal already before he came:

Not debating that point. Just that its (R moshes heter to rely on govt regs) not something that can be called a previous unwrittien mesorah for dorei doros. We know that there were very chashuv erlicher yidden in the US in the late 1800- early 1900 but 50 years is not something that can be called a minhag for dorei doros... As is the lack of history of "company milk" and "regulations" for a significant amount of time.
Rabbinic leaders were incensed and, until the situation would be rectified ruled that, under such circumstances, one would be permitted to adopt the lenient view of the Pri Chodosh (Yore Deah 115:15) who permitted the consumption of chalav akum when the non-kosher milk is less expensive than the kosher variety.
I don't think the Pri Chodosh says what Rav Moshe says...Maybe in result but def not in reason...
