when I lived in East Texas I purchased raw goat's milk from a colleague at work.
A guy I met at a Texas group campout told me that the legal way to sell raw goat milk and cheese in Texas was for someone like me to buy a part of or a whole goat.......
My wife and kids drink organic cow's milk which I don't digest well, partly due to the ultra pasteurization but also the fats in it.
As a kid for several years we had about 30 head of dairy cattle that I helped with, but we only did the minimal amount of pasteurization and drank most of it within about 24 hours.
Edit: Latte Da Dairy sells their goat's cheese through some local markets in the DFW
Texasrealmilk dot org and the goat associations may have more info I should probably try to contact them more directly.
This link explains how the goat/cow shares typically works:
