"We always kept a pitcher of milk everyday to drink. In the spring, it always tasted like onions."
The cows probably ate dandilions. Just a guess.
"As long as you take good care of your cows, and have them tested, its okay to drink the milk, but I am hesitant unless I know the people really well to drink it unpasturized."
VERY true. I had complete control of the milking production (while making a whopping $2/hr), so I knew exactly what I was ingesting. I knew a few dairy farmers who had the same level of quality. But, there were some who didn't know how to run a Grade A process.
So I totally believe milk output needs to be tested every time. But, government doesn't need to mandate ALL milk must be pasteurized - let the distributors test bacteria like they did with EVERY shipment from every dairy farm I worked on back in the day. Raw is SO much more healthy - if it's safe.
I agree totally with your philosophy on milk. I think the spring pasture had quite a few wild onions. They abound in Missouri for some reason.
We have a bunches of them all over our yard right now. They are edible, but pretty strong in flavor.
