Assessment of Human BSE Risks Through the Use of Cattle-Derived MBM *1 in Chicken, Pig, and Others Feed (Prions).

Abstract

Food Safety Commission of Japan (FSCJ) conducted a risk assessment regarding the use of so-called "cattle-derived MBM" as raw material in feed intended for chickens, pigs, and others in response to a request of the Ministry of Agriculture, Forestry and Fisheries (MAFF). As far as the current risk mitigation measures against BSE are implemented, BSE prions are highly unlikely to be accumulated in the cattle, sheep, and goat parts which would be used as raw materials of feed for chickens, pigs, and others . There are negligible occurrence of cattle-derived MBM to be fed to cattle and other ruminants, as long as the Japanese current risk mitigation measures against feeding cattle-derived MBM to ruminants continue to be abided. Furthermore, oral transmission of BSE prions to chickens, pigs, and others is unlikely to occur, based on accumulated scientific findings. The risk of human infection with BSE is considered to be highly unlikely. FSCJ thus concluded negligible adverse human health-effects of foods from chickens, pigs, and others, in Japan's circumstances where cattle-derived MBM is used as raw materials for feed these specified animals.
