United States Department of Agriculture (USDA) Secretary Tom Vilsack characterizes regulation by USDA's Grain Inspection, Packers & Stockyards Administration (GIPSA) to be released on Tuesday, June 22, 2010, as "aggressive" and noted that if the rules are implemented, they would constitute the most dramatic change to the regulation of the livestock marketplace since the Packers & Stockyards Act (PSA) was enacted in 1921.
