I commented about it above, also, we (me and my brother) used to do the same thing when we were kids, in rural Romania (a village near the Carpathians). Immediately after our grandma or our our grandpa had finished milking the cows we (meaning me and my brother) would eat out with a spoon the foam-y thing that was forming on top of the bucket full of milk that had just come out of the cows. We did that my entire childhood (so from when when I was about 5 to my early 20s, so into my early adulthood), never had any health-related issues with it. In fact that is one of my fondest memories when it comes to my grandparents.
