    • The increasing number of BSE diseases in cattle in recent years is associated with feeding animals meat meal, animal blood meal and animal bone meal. Slaughterhouse wastes from sheep (scrapie pathogens), goats (scrapie pathogens) and from cattle (BSE pathogens) are processed into meat meal, animal blood meal and into animal bone meal and are then fed to cattle. All methods used in Europe for producing meat meal, animal blood meal and animal bone meal have been proven unreliable in destroying the pathogens and thus in providing protection against the transmission of the disease (BSE). In these methods, the raw material (animal cadavers and wastes) are comminuted, heated and dried. After pressing out the fat, the material is ground into bone meal. The temperatures used for sterilizing are, however, incapable of destroying the pathogen. As a result, infectious meat-and-bone meal as well as infectious animal fat enter the feed cycle. Meat meal, animal blood meal and animal bone meal are fed to cattle, pigs, sheep, poultry and cultivated fish. The inventive method and the procedure provide a novel approach to destroying and eradicating the proteins contained in the meat meal, animal blood meal and animal bone meal and, with them, the pathogens of prion diseases. The principle is based on the chemical breakdown of the proteins into their individual parts: amino acids. Thanks to this procedure, information can no longer be transferred thereby preventing the triggering of disease. In addition, the protein involved in the disease BSE is broken down into its constituents and can no longer unleash its harmful effect. After decomposition is complete, the solution is neutralized with amino acids (rendered pH neutral by adding alkaline or acid neutralizing agents), and the amino acids are recovered as solid matter by drying. This solid matter can be used in agriculture (e.g. as an animal feed supplement) in place of present day meat meal, animal blood meal and animal bone meal.
