This Act is P.L. 85-36 (May 23, 1957) which prohibits the movement of plant pests from a foreign country into or through the United States unless authorized by USDA. The law gives USDA’s Animal and Plant Health Inspection Service broad authority to inspect, seize, quarantine, treat, destroy or dispose of imported plant and animal materials that are potentially harmful to U.S. agriculture, horticulture, forestry, and, to a certain degree, natural resources.
