Abstract

The United States has built a triple firewall system to prevent the introduction or emergence of bovine spongiform encephalopathy. The firewalls are preventing bovine spongiform encephalopathy's introduction through bans on imports of animals and animal products, actively looking for bovine spongiform encephalopathy in the US cattle herd, and banning ruminant animal feed supplements found to carry the infectious agent and spread the disease in England.
