A theory has been establlished that BSE is spread through feedstuffs, more precisely, meat-bone flour which contains infective proteins of ruminants, and legislature has been passed throughout the world with the objective of preventing the entry of meat-bone flour into the food chain. The complete ban of the use of meat-bone flour for all farm animals (with exception of fish flour for non-ruminants) and an adequate thermal treatment in the production of meat-bone flour (133 degC, 3 bar, 20 min) are the elements on which the European Union (EU) legislature is based. The regulations in Serbia include a ban on the use of meat-bone flour in cattle feedstuffs and a ban on imports of beef proteins. The implementation of this legislature throughout the world requires the corresponding analytical means. At the present time, there are several available possibilities: optic microscopy, PCR, immunoprobes, spectroscopic methods, and several other which are still being examined for use for this purpose.
