Milkshed, Milk shed, or Milk-shed, is a region producing milk that may be supplied to the area of demand without spoiling. [1] It is an area geographically demarcated for the collection of milk or milk products. Due to increases in technology the milk shed has grown from 30 mile radius to over 300 miles. [2] Thus, nearly every farm in the Northeastern United States and Northwest Europe are in at least one milkshed.
The term milkshed originated in America around 1925-1930 on the model of "watershed". [3]
