As of Jan. 2013, the sale of raw milk in stores is legal in 12 states. 17 states only permit raw milk sales on farms; 4 states only allow raw milk acquisition through "cow-share" agreements; and in 17 other states all sales of raw milk are prohibited.
In a 1939 strike by the Dairy Farmers Union, milk farmers engaged in militant tactics such as blocking roads, confiscating and spilling out milk, physically fighting strike breakers, and setting fire to trucks that tried to cross road blockades.
In 1996, the California Milk Processors Board and Mattel came out with a limited edition "got milk?" Barbie doll to advertise milk.
Since 1937, the wholesale price of milk has been set by the federal government under federal milk marketing orders (FMMO's). In 2006, about 60% of all milk sold in the United States was regulated under these FMMO's.
