Ewww lol, but I defend your right to drink it if you like.
It would be interesting to see what kind of labels would have to go on this type of milk. Perhaps a list of different bacterias (E.coli, salmonella,listeria) found in each batch? Would that make people too nervous to buy it? I just don't know but I know the government would not want to be held responsible if a few people started getting sick.
I would think just like the human bladder, urine is suppose to be sterile. Milk should be sterile also but just like when someone gets a bladder infection, bacteria does get into the milk, plus whatever outside contamination.
Perhaps Ron Paul will have a chance to show us what a great health advocate his is. :)
