Parents for Better D.C. School food advocate milk with no added sugars or flavors and no bovine growth hormone.
Most of the nation's commercial dairy cows are treated with a genetically-engineered growth hormone that encourages them to produce more milk. They also die sooner. Monsanto, the creator of this particular hormone, for years waged a campaign to prevent milk producers who don't use it from saying so on their milk labels. Then, Monsanto abruptly sold rights to the product to another company, Posilac.
There have been concerns for years about how cows might pass the growth hormone along to humans through the milk and what harm that might cause. Of particular concern is the hormone's potential for causing breast cancer even in young women.
