The Poisonous Plant Research Laboratory, a federal agency under the United States Department of Agriculture (USDA), is dedicated to investigating poisonous plants and their toxins, developing diagnostic and prognostic procedures, identifying conditions leading to poisoning, and devising management strategies and treatments to reduce livestock losses. Through comprehensive research efforts, this agency plays a vital role in safeguarding the nation’s agricultural sector and livestock industry. By advancing knowledge about plant-induced poisoning and providing ranchers with effective tools and practices, the Poisonous Plant Research Laboratory actively contributes to the overall health and sustainability of livestock, thereby supporting the well-being of both animals and the livelihood of farmers.
