Reviewing the research of a number of authors and law regulations of Europen Union on inedible by-products obtained from slaughtered animals (1990-1999), this paper suggests the possibility of utilization of these inedible by-products for animal feed without hazard of spreading bovine spongiform encephalopathy (BSE). It has been proved that the cause of this disease is pathological prion (PrP(SK)) which is more resistant than bacteria found in animal raw materials and that BSE epidemia has been induced by human factor, first of all by using meat&bone meal produced from dead sheep and inedible by-products of slaughtered sheep processed by inadequate technological process. The production of sanitary safe and biologically valuable meat&bone meal requires the special attention that should be paid when collecting and sorting these inedible products according to hazard. The authors have proposed the safe technological process for meat&bone production from the adequate raw materials. This process includes high temperature, wet sterilization of chopped material (40 mm) at 136 deg C in the period of 20 minutes and pressure of 3.2 bars with constant of critical points in this technological process.
