Universal Laboratories Building

Universal Laboratories Building is a building in Dassel, Minnesota, United States, listed on the National Register of Historic Places. It was listed on the National Register for its role in the production of ergot from the mid-1930s through the late 1960s.The business was established in 1935 as Rice Laboratories, as a manufacturer of yeast for livestock feed. Yeast was used as a feed supplement because the enzymes fermenting in the digestive tracts of hogs and poultry would break down food and help in nutrient absorption. In 1937, the company built a new building on the north edge of town. In that same year, the manager of the company, Lester R. Peel, started production of ergot. Local farmers were discarding rye that was infected with sclerotia growths, because the ergot could cause deadly poisoning. Peel, a former school teacher, understood that the ergot also had medical applications, such as controlling postpartum bleeding and treating vasoconstriction, hypertension, vascular headaches, and migraines.Peel gave the ergot business the name Universal Laboratories. Production initially began with ergotic rye bought from local farmers. Universal Laboratories staff would then bring the rye through small mills that would break up the rye kernels. They would then pick the grain from the conveyor belt and let the ergot fall into a receptacle for bagging. The company also hired people to work from their homes in Dassel picking and bagging ergot. Later, the process was improved by new machines that automated the process of separating the ergot from the rye. The grain was passed through mills that would flow into gravity separators, which had spiraling chutes that would separate the light ergot kernels from the heavier rye kernels.
