I always wonder what's the differenece between Organic/Regular Milk apart from the price

The difference will be the potential to have residues of the fertilisers, feed - including additives which often contain synthetic hormones and antibiotics, and any pesticides applied either to the animal directly or indirectly via the pasture she grazes on and the supplementary feed she eats. The regulatory authorities will specify these must be below accepted safe limits.
Under an organic system there are limitations on what can be used as a farm input. The basis of "organics" is that there minimal inputs of things which are not in a naturally occurring form. Anything not meeting that criteria is usually under strict limitations. No synthetic fertilisers, herbicides, pesticides, hormones, antibiotics etc.
If these things show up in human breast milk in certain situations - no one can convince me they aren't in cows milk. Usually these sort of tests aren't carried out until there is a percieved problem - which doesn't mean they aren't there!
I grew up on milk from a "house cow" on the farm and her milk took on a different taste depending on what the dominant grass in the pasture was at the time. No one will ever convince me the other things applied to that pasture, supplementary feed etc don't come through in the milk.
You just need to make a concious choice on these things I think.
"Organic" grown foods just have less potential to contain chemical residues that may one day turn out to be undesirable or sometimes downright harmful!!
