Remember our post on Starbucks getting rid of milk from cows treated with rBGH in half its stores?

Apparently, rBGH does not show up in milk--the fluid itself is rBGH free. However, cows given rBGH are at a much higher risk of mastitis, an udder infection usually treated with antibiotics, which do come through the milk.

See the NRN Food Service Blog for a fleshing out of the semantics.
