Does a dairy product that labels itself organic mean it's rBST free?

what about milk that is labeled "cows not treated with rbST or rbst-free", but not labeled Organic. Are these suppliers avoiding the expense of becoming organic to keep lower prices? Or is there something else I'm not informed of?
thanks,

In order to qualify for the organic label, organic farmers are prohibited from using synthetic growth hormones such as recombinant Bovine Growth Hormone (rbST or rgBH) on their livestock. Thus, all milk that is marketed as organic cannot have been produced using synthetic hormones.

I went running to my fridge after reading this to double-check that our organic milk was ok. Luckily, it was. Whew!

That is correct. Some products have rBST while others are labeled as not having it. If you are interested in organic foods that do not have rBST, most are labeled as such.

Hope this helps.
