• Resumen

  • The article discusses the origin of mad cow disease also called bovine spongiform encephalopathy (BSE). Topics include an overview of the process called rendering which separates the ground-up components of animals to produce feed and kills prions that cause disease, the cost-cutting measures taken by renderers such as use of a centrifuge instead of heat and solvents to separate nonedible parts including hooves, spinal cords, and brains, and the global spread of the disease as a result.
