(3)Regulation (EC) No 183/2005 of the European Parliament and of the Council of 12 January 2005 laying down requirements for feed hygienenote provides for specific requirements for feed businesses using coccidiostats and histomonostats in the production of feed. In particular, the operators concerned have to take all appropriate measures concerning facilities and equipment, production, storage and transport in order to avoid any cross-contamination, and this in accordance with the obligations provided for in Articles 4 and 5 of the above mentioned Regulation. The establishment of maximum levels of unavoidable carry-over of coccidiostats and histomonostats in non-target feed in accordance with Directive 2002/32/EC should not interfere with the primary obligation of operators to apply good manufacturing practices aiming at avoiding this cross-contamination. Continued effort is therefore still needed by the operators concerned in order to avoid the presence of such undesirable substances in animal feed.
