This looks like a clip from "the
corporation." It is a movie I watched a couple years ago -- and I've been drinking organic dairy (I like Horizon) products ever since! I figure the chance of nipple puss being in organic milk products is lower. I might be wrong... but I like milk too much to give it up completely and that's the best I can figure to do.
Honestly, the entire movie is worth seeing... this milk products issue (and cover up through the media) was used as one example of many to persuade movie watchers that the corporate structure is set up to value profit only and that without government regulation on the corporate structure (because who else will look out for the public interests... like health issues) we are pretty much effed. That's at least what I got out of it.
