The issue is the fact that people pick and choose which Gaon-among-Geonim to follow when and because it is comfortable for them to do so.
This is a problem in both direction (machmir and maikel). However, I follow my Rabbi – so if he says Chalav Stam is OK, I follow that. He is my posek and I am consistent.
I wonder if the health risks associated with non-organic dairy (lower nutrient content, antibiotic issues etc) change the status since the long term effects of non-organic milk is unknown but considered to be causing some issues today.
and i once heard that after the iron curtain fell yoshon became an issue here in america. beforehand the supply was backed up so everything was yoshon, but after the cold war american started supplying russia with flour so that ended.
One year, my Rav told me that there is still a 2-3 year backup in wheat in America, and there is little chance of actual problems with yoshon. I don’t know if that still applies though.
