This is neat. I wonder about animal to human transmission? I'm more or less a recluse so my human interaction is maybe one... once every three weeks. I drink raw milk from cows I own. This seems to help with my gut problems. So that's the lineage of thinking I'm coming from. Not making any claims, just thinking my human to human interaction is pretty limited unlike my animal interactions.
There is a lot on youtube, instructional wise. Some of the challenges were more just the learning process. For raw milk itself, the mainstream society has a very different view on it. The reason why I went with it is a bit of a long story. My gastro wanted to switch my meds to a drug that would put me at higher risk of complications to even just the basic of colds. If that failed I was going to need to have my colon removed. Figured I'd take the gamble with raw milk. At first purchased it from a few farmers. After a few weeks on it my condition began to improve, a few months later I was in remission. A few of the farmers went under so I decided to get my own cows cause I have the land. I don't sell. I use everything I produce. I personally prefer a mix of breeds over just holsteins (edit; https://www.pelliclemag.com/home/2020/1/28/men-who-stare-at-...). I try to do everything so its biodynamic and add back to the land. Still a learning process.
