Business and Technology  Dairyland Rat Poison container, made for Wisconsin Pharmacal Co., Milwaukee, Wisconsin, circa 1955-1965. This was a warfarin-based poison. Warfarin, which is still the most widely used rodenticide worldwide, was developed by Karl Paul Link at the University of Wisconsin
and patented by the Wisconsin Alumni Research Foundation (WARF) in 1947. It inhibits blood clotting and causes death by massive internal bleeding. UW researchers later developed an improved formula, called prolin, by adding a bactericide that inhibits the body's production of vitamin K. (1999.143.34) Curator : David Driscoll
