Fighting on a Battlefield the Size of a Milk Label

It may be the last stand of Posilac. A new advocacy group closely tied to Monsanto has started a counteroffensive to stop the proliferation of milk that comes from cows that aren't treated with synthetic bovine growth hormone.

The group, called American Farmers for the Advancement and Conservation of Technology, or Afact, says it is a grass-roots organization that came together to defend members' right to use recombinant bovine somatotropin, also known as rBST or rBGH, an artificial hormone that stimulates milk production. It is sold by Monsanto under the brand name Posilac.

Dairy farmers are indeed part of the organization. But Afact was organized in part by Monsanto and a Colorado consultant who lists Monsanto as a client.

Afact has also received help from Osborn & Barr, a marketing firm whose founders include a former Monsanto executive. The firm received a contract in 2006 to help with the Posilac campaign.
