“The Justice Department’s top antitrust enforcer at a September 20 Senate Judiciary Committee hearing in St. Albans, Vt., told a packed hall of dairy farmers that increased concentration in the dairy industry merited a closer look by the department. Assistant Attorney General Christine Varney said the department is reviewing market concentration, the relationship between dairy co-ops and milk processors, “and how we’ve evolved to the point where the co-ops are basically captive of one distributor. I want to understand how we got there and what kind of competition exists.”””
