24. 7. 96 Official Journal of the European Communities No L 184/43 COMMISSION DECISION of 18 July 1996 on the approval of alternative heat treatment systems for processing animal waste with a view to the inactivation of spongiform encephalopathy agents (Text with EEA relevance) (96/449/EC) THE COMMISSION OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Community, Having regard to Council Directive 90/667/EEC of 27 November 1990 laying down the veterinary rules for the disposal and processing of animal waste, for its placing on the market and for the prevention of pathogens in feed- stuffs of animal or fish origin and amending Directive 90/425/EEC ('), as last amended by the Act of Accession of Austria, Finland and Sweden, and in particular Annex II, Chapter II, paragraph 6 (c) thereof, Whereas Commission Decision 92/562/EEC (), as amended by the Act of Accession of Austria, Finland and Sweden, was adopted to define alternative systems of heat treatment provided for in paragraph 6 (c) of Annex II, Chapter II to Directive 90/667/EEC; Whereas in 1994 phase 1 of a scientific study into the physical parameters which must be applied in order to inactivate the agents of BSE and scrapie ‘identified the minimum parameters necessary for inactivation of the BSE agent; it also identified certain processes which were not effective; Whereas Commission Decision 94/382/EC of 27 June 1994 on the approval of alternative heat treatment systems for processing animal waste of ruminant origin, with a view to the inactivation of spongiform encephalo- pathy agents (}), as amended by Decision 95/29/EC (%), has been adopted to establish the minimum standards for use in the alternative systems provided for in Decision 92/562/EEC, and to prohibit the use of the systems which are not effective; () OJ No L 363, 27. 12. 1990, p. S1. () O] No L 359, 9. 12. 1992, p. 23. () O] No L 172, 7. 7. 1994, p. 25. () OJ No L 38, 18. 2. 1995, p. 17. Whereas the minimum standards laid down in Decision 94/382/EC were considered to be provisional, pending the results of future studies; Whereas the results of phase 2 of this study showed that only one system tested was capable of fully inactivating the scrapie agent in meat-and-bone meal; Whereas, therefore, it is necessary to ensure that systems which have been shown to be ineffective are not used for the processing of mammalian animal waste in order to protect animal health from the hazard of spongiform encephalopathy agents in animal feed, unless an effective sterilization phase is added to the process; Whereas, at its meeting on 1 to 3 April 1996, the Council concluded that a Commission Decision in accordance with the Standing Veterinary Committee procedure should be adopted to require that all animal waste of mammalian origin in the Community is to be processed by a method that has been demonstrated as being de facto effective for the inactivation of the agents of scrapie and BSE; whereas the only such method at present is the application of heat in a batch-rendering system which achieves minimum 133°C at 3 bar for a minimum period of 20 minutes; whereas this may be applied as the sole process or as a pre- or post-process sterilization phase; Whereas it is necessary to define the maximum particle size and the minimum time and temperature to be applied in approved systems, in order to ensure that such systems are running in accordance with procedures which have been shown to be effective; Whereas specific rules for the control of plants must be put in place; Whereas on 12 December 1994 the Scientific Veterinary Committee recommended detailed procedures for the validation of rendering processes; whereas these proced- ures should be used to ensure that the parameters laid down in this Decision are achieved on a plant-by-plant basis;
