@rugbygirl - My understanding is that the EU banned it not because the milk is harmful to humans, but because the use of BGH is hard on the cows. Like the article mentions, it shortens their lifespans (pretty dramatically, I think), etc. It's an animal welfare thing.
A lot of people do think that organic milk must be "healthier." So far, there's no proof that it is. But we buy it in my house anyway because my husband likes the taste much better and because of the animal welfare aspect.
